+<p class="lead magick-description">It's possible you don't want to concern yourself with advanced installation under Linux or Linux systems. If so, you also have the option of installing a pre-compiled <a href="../www/download.html#linux">binary release</a> or if you still want to install from source without all the fuss see the simple <a href="install-source.html#linux">Install From Source</a> instructions. However, if you want to customize the configuration and installation of ImageMagick under Linux or Linux systems, lets begin.</p>
+
+<h2><a class="anchor" id="download"></a>Download & Unpack</h2>
+
+<p>ImageMagick builds on a variety of Linux and Linux-like operating systems including Linux, Solaris, FreeBSD, Mac OS X, and others. A compiler is required and fortunately almost all modern Linux systems have one. Download <a href="https://download.imagemagick.org/ImageMagick/download/ImageMagick.tar.gz">ImageMagick.tar.gz</a> from <a href="../download">imagemagick.org</a> or a <a href="../www/download.html">mirror</a> and verify the distribution against its <a href="https://download.imagemagick.org/ImageMagick/download/digest.rdf">message digest</a>.</p>
+
+<p>Unpack the distribution it with this command:</p>
+
+<ul><pre class="bg-light text-dark"><samp>tar xvzf ImageMagick.tar.gz</samp></pre></ul>
+
+<p>Now that you have the ImageMagick Linux/Linux source distribution unpacked, let's configure it.</p>
+
+
+<h2><a class="anchor" id="configure"></a>Configure</h2>
+
+<p>The configure script looks at your environment and decides what it can cobble together to get ImageMagick compiled and installed on your system. This includes finding a compiler, where your compiler header files are located (e.g. stdlib.h), and if any delegate libraries are available for ImageMagick to use (e.g. JPEG, PNG, TIFF, etc.). If you are willing to accept configure's default options, and build from within the source directory, you can simply type:</p>
+
+<ul><pre class="bg-light text-dark"><code><span class="crtprompt">$ </span><span class='crtin'>cd ImageMagick-7.1.0-13</span><span class='crtout'></span><span class="crtprompt">$ </span><span class='crtin'>./configure</span></code></pre></ul>
+<p>Watch the configure script output to verify that it finds everything that
+ you think it should. Pay particular attention to the last lines of the script output. For example, here is a recent report from our system:</p>
+
+<ul><pre class="pre-scrollable bg-light text-dark"><samp>ImageMagick is configured as follows. Please verify that this configuration
+matches your expectations.

<p>The ImageMagick pixel cache is a repository for image pixels with up to 32 channels. The channels are stored contiguously at the depth specified when ImageMagick was built. The channel depths are 8 bits-per-pixel component for the Q8 version of ImageMagick, 16 bits-per-pixel component for the Q16 version, and 32 bits-per-pixel component for the Q32 version. By default pixel components are 32-bit floating-bit <a href="../www/high-dynamic-range.html">high dynamic-range</a> quantities. The channels can hold any value but typically contain red, green, blue, and alpha intensities or cyan, magenta, yellow, black and alpha intensities. A channel might contain the colormap indexes for colormapped images or the black channel for CMYK images. The pixel cache storage may be heap memory, disk-backed memory mapped, or on disk. The pixel cache is reference-counted. Only the cache properties are copied when the cache is cloned. The cache pixels are subsequently copied only when you signal your intention to update any of the pixels.</p>

<p>In our discussion of the pixel cache, we use the <a href="magick-core.html">MagickCore API</a> to illustrate our points, however, the principles are the same for other program interfaces to ImageMagick.</p>
<p>When the pixel cache is initialized, pixels are scaled from whatever bit depth they originated from to that required by the pixel cache. For example, a 1-channel 1-bit monochrome PBM image is scaled to 8-bit gray image, if you are using the Q8 version of ImageMagick, and 16-bit RGBA for the Q16 version. You can determine which version you have with the <a class="text-nowrap" href="../www/command-line-options.html#version">-version</a> option: </p>

<p>As you can see, the convenience of the pixel cache sometimes comes with a trade-off in storage (e.g. storing a 1-bit monochrome image as 16-bit is wasteful) and speed (i.e. storing the entire image in memory is generally slower than accessing one scanline of pixels at a time). In most cases, the benefits of the pixel cache typically outweigh any disadvantages.</p>

For this reason we recommend that you only read or update a scanline or a few scanlines of pixels at a time. However, you can get any rectangular region of pixels you want. GetAuthenticPixels() requires that the region you request is within the bounds of the image area. For a 640 by 480 image, you can get a scanline of 640 pixels at row 479 but if you ask for a scanline at row 480, an exception is returned (rows are numbered starting at 0).

-<h3>Cache Storage and Resource Requirements</h3>
+<h2>Cache Storage and Resource Requirements</h2>
<p>Recall that this simple and elegant design of the ImageMagick pixel cache comes at a cost in terms of storage and processing speed. The pixel cache storage requirements scales with the area of the image and the bit depth of the pixel components. For example, if we have a 640 by 480 image and we are using the non-HDRI Q16 version of ImageMagick, the pixel cache consumes image <var>width * height * bit-depth / 8 * channels</var> bytes or approximately 2.3 mebibytes (i.e. 640 * 480 * 2 * 4). Not too bad, but what if your image is 25000 by 25000 pixels? The pixel cache requires approximately 4.7 gibibytes of storage. Ouch. ImageMagick accounts for possible huge storage requirements by caching large images to disk rather than memory. Typically the pixel cache is stored in memory using heap memory. If heap memory is exhausted, we create the pixel cache on disk and attempt to memory-map it. If memory-map memory is exhausted, we simply use standard disk I/O. Disk storage is cheap but it is also very slow, upwards of 1000 times slower than memory. We can get some speed improvements, up to 5 times, if we use memory mapping to the disk-based cache. These decisions about storage are made <var>automagically</var> by the pixel cache manager negotiating with the operating system. However, you can influence how the pixel cache manager allocates the pixel cache with <var>cache resource limits</var>. The limits include:</p>

<p>Since we process multiple simultaneous sessions, we don't want any one session consuming all the available memory.With this policy, large images are cached to disk. If the image is too large and exceeds the pixel cache disk limit, the program exits. In addition, we place a time limit to prevent any run-away processing tasks. If any one image has a width or height that exceeds 8192 pixels, an exception is thrown and processing stops. As of ImageMagick 7.0.1-8 you can prevent the use of any delegate or all delegates (set the pattern to "*"). Note, prior to this release, use a domain of "coder" to prevent delegate usage (e.g. domain="coder" rights="none" pattern="HTTPS"). The policy also prevents indirect reads. If you want to, for example, read text from a file (e.g. caption:@myCaption.txt), you'll need to remove this policy.</p>
<p>Note, the cache limits are global to each invocation of ImageMagick, meaning if you create several images, the combined resource requirements are compared to the limit to determine the pixel cache storage disposition.</p>

-<h3>Distributed Pixel Cache</h3>
+<h2>Distributed Pixel Cache</h2>
<p>A distributed pixel cache is an extension of the traditional pixel cache available on a single host. The distributed pixel cache may span multiple servers so that it can grow in size and transactional capacity to support very large images. Start up the pixel cache server on one or more machines. When you read or operate on an image and the local pixel cache resources are exhausted, ImageMagick contacts one or more of these remote pixel servers to store or retrieve pixels. The distributed pixel cache relies on network bandwidth to marshal pixels to and from the remote server. As such, it will likely be significantly slower than a pixel cache utilizing local storage (e.g. memory, disk, etc.).</p>

-<h3>Cache Views</h3>
+<h2>Cache Views</h2>
<p>GetVirtualPixels(), GetAuthenticPixels(), QueueAuthenticPixels(), and SyncAuthenticPixels(), from the MagickCore API, can only deal with one pixel cache area per image at a time. Suppose you want to access the first and last scanline from the same image at the same time? The solution is to use a <var>cache view</var>. A cache view permits you to access as many areas simultaneously in the pixel cache as you require. The cache view <a href="api/cache-view.html">methods</a> are analogous to the previous methods except you must first open a view and close it when you are finished with it. Here is a snippet of MagickCore code that permits us to access the first and last pixel row of the image simultaneously:</p>

-<h3>Magick Persistent Cache Format</h3>
+<h2>Magick Pixel Cache Format</h2>
-<p>Recall that each image format is decoded by ImageMagick and the pixels are deposited in the pixel cache. If you write an image, the pixels are read from the pixel cache and encoded as required by the format you are writing (e.g. GIF, PNG, etc.). The Magick Persistent Cache (MPC) format is designed to eliminate the overhead of decoding and encoding pixels to and from an image format. MPC writes two files. One, with the extension <code>.mpc</code>, retains all the properties associated with the image or image sequence (e.g. width, height, colorspace, etc.) and the second, with the extension <code>.cache</code>, is the pixel cache in the native raw format. When reading an MPC image file, ImageMagick reads the image properties and memory maps the pixel cache on disk eliminating the need for decoding the image pixels. The tradeoff is in disk space. MPC is generally larger in file size than most other image formats.</p>
+<p>Recall that each image format is decoded by ImageMagick and the pixels are deposited in the pixel cache. If you write an image, the pixels are read from the pixel cache and encoded as required by the format you are writing (e.g. GIF, PNG, etc.). The Magick Pixel Cache (MPC) format is designed to eliminate the overhead of decoding and encoding pixels to and from an image format. MPC writes two files. One, with the extension <samp>.mpc</samp>, retains all the properties associated with the image or image sequence (e.g. width, height, colorspace, etc.) and the second, with the extension <samp>.cache</samp>, is the pixel cache in the native raw format. When reading an MPC image file, ImageMagick reads the image properties and memory maps the pixel cache on disk eliminating the need for decoding the image pixels. The trade-off is in disk space. MPC is generally larger in file size than most other image formats.</p>
<p>The most efficient use of MPC image files is a write-once, read-many-times pattern. For example, your workflow requires extracting random blocks of pixels from the source image. Rather than re-reading and possibly decompressing the source image each time, we use MPC and map the image directly to memory.</p>
-<h3>Best Practices</h3>
+<h2>Best Practices</h2>
<p>Although you can request any pixel from the pixel cache, any block of pixels, any scanline, multiple scanlines, any row, or multiple rows with the GetVirtualPixels(), GetAuthenticPixels(), QueueAuthenticPixels, GetCacheViewVirtualPixels(), GetCacheViewAuthenticPixels(), and QueueCacheViewAuthenticPixels() methods, ImageMagick is optimized to return a few pixels or a few pixels rows at time. There are additional optimizations if you request a single scanline or a few scanlines at a time. These methods also permit random access to the pixel cache, however, ImageMagick is optimized for sequential access. Although you can access scanlines of pixels sequentially from the last row of the image to the first, you may get a performance boost if you access scanlines from the first row of the image to the last, in sequential order.</p>

<p class="lead magick-description">Use contrast limited adaptive histogram equalization (AHE) to improve contrast in images. Ordinary histogram equalization computes a global equalization whereas an adaptive method computes several histograms, each corresponding to a distinct section of the image, and uses them to redistribute the lightness values of the image. It is suitable for improving the local contrast and enhancing the definitions of edges in each region of an image. A variant of adaptive histogram equalization, contrast limited adaptive histogram equalization (CLAHE) limits AHE's tendency to overamplify noise in relatively homogeneous regions of an image.</p>
<p>CLAHE is supported as of ImageMagick 7.0.8-24 with the <a href="../www/command-line-options.html#clahe">-clahe</a> option:</p>

</ul>
-<p> The image is divided into tiles of <var>width</var> and <var>height</var> pixels. Append <code>%</code> to define the width and height as percentages of the image's dimensions. The tile size should be larger than the size of features to be preserved and respects the aspect ratio of the image. Add <code>!</code> to force an exact tile width and height. <var>number-bins</var> is the number of histogram bins per tile (min 2, max 65536). The number of histogram bins should be smaller than the number of pixels in a single tile. <var>clip-limit</var> is the contrast limit for localized changes in contrast. A clip-limit of 2 to 3 is a good starting place (e.g. -clahe 50x50%+128+3). Very large values will let the histogram equalization do whatever it wants to do, that is result in maximal local contrast. The value 1 will result in the original image. Note, if the number of bins and the clip-limit are omitted, they default to 128 and no clipping respectively.</p>

<p>ImageMagick supports color profiles, however, for images without a profile or a declaration of colorspace, ImageMagick assumes non-linear sRGB. Most image processing algorithms assume a linear colorspace, therefore it might be prudent to convert to linear color or remove the gamma function before certain image processing algorithms are applied. For example,</p>

<p>Note that LinearGray is new as of Imagemagick 6.9.9-29 and 7.0.7-17.</p>
<p>The same concept is needed when separating channels. Normally, the conversion to separate each channel of an sRGB color image produces separate non-linear grayscale images. However the same concept can be applied, if it is desired to keep the separate channels as linear grayscale. For example, the following produces linear grayscale channels.</p>

<p>When separating and recombining channels, with potential intermediate processing, it is important to identify the colorspace used, especially during the recombination. For example,</p>

+<p>In the above example, the separated channels are non-linear and the default for <samp>-combine</samp> is to assume non-linear channels. So the result is the same as the input.</p>
If one desires to separate to linear grayscale channels, recombine them later back to non-linear color, perhaps after some processing, then use the same concept as above for maintaining linear grayscale:</p>

<p>When converting to another colorspace and back, such as between sRGB and HSL, the following two commands handle the first case of non-linear channels and the second case of linear channels:</p>
-<pre class="highlight"><code>magick myimage.png -colorspace HSL -separate myimage_channels_%d.png

<p>A majority of the image formats assume an sRGB colorspace (e.g. JPEG, PNG, etc.). A few support only linear RGB (e.g. EXR, DPX, CIN, HDR) or only linear GRAY. A few formats support CMYK. For example JPG does, but PNG does not. Then there is the occasional format that also supports LAB (that is CieLAB) (e.g. TIFF, PSD, JPG, JP2).

For colorspace Gray, be sure to use a start value lower than the stop value. Note that Hue is cyclical -- 0 and 360 are the same.

-<p>The format of an sRGB value in hexadecimal notation is a '#' immediately followed by either three, six, or twelve hexadecimal characters. The three-digit sRGB notation (#rgb) is converted into six-digit form (#rrggbb) by replicating digits, not by adding zeros. For example, #fb0 expands to #ffbb00. This ensures that white (#ffffff) can be specified with the short notation (#fff) and removes any dependencies on the color depth of the image. Use the hexadecimal notation whenever performance is an issue. ImageMagick does not need to load the expansive color table to interpret a hexadecimal color, e.g., <code>#000000</code>, but it does if <code>black</code> is used instead.</p>

<p>One advantage of HSB or HSL over RGB is that it can be more intuitive: you can guess at the colors you want, and then tweak. It is also easier to create sets of matching colors (by keeping the hue the same and varying the brightness or lightness and saturation, for example).</p>

-<h5>Filename Globbing</h5>
-<p>In Unix shells, certain characters such as the asterisk (<code>*</code>) and question mark (<code>?</code>) automagically cause lists of filenames to be generated based on pattern matches. This feature is known as globbing. ImageMagick supports filename globbing for systems, such as Windows, that does not natively support it. For example, suppose you want to convert <code>1.jpg</code>, <code>2.jpg</code>, <code>3.jpg</code>, <code>4.jpg</code>, and <code>5.jpg</code> in your current directory to a GIF animation. You can conveniently refer to all of the JPEG files with this command:

-<h5>Explicit Image Format</h5>
+<h4>Explicit Image Format</h4>
<p>Images are stored in a myriad of image formats including
the better known JPEG, PNG, TIFF and others. ImageMagick must know the format
of the image before it can be read and processed. Most formats have a
signature within the image that uniquely identifies the format. Failing
that, ImageMagick leverages the filename extension to determine the format.
-For example, <code>image.jpg</code> or <code>image.JPG</code> tells ImageMagick
+For example, <samp>image.jpg</samp> or <samp>image.JPG</samp> tells ImageMagick
it is reading an image in the JPEG format. </p>
<p>In some cases the image may not contain a signature
and/or the filename does not identify the image format. In these cases an
explicit image format must be specified. For example, suppose our image
-is named <code>image</code> and contains raw red, green, and blue intensity
+is named <samp>image</samp> and contains raw red, green, and blue intensity
values. ImageMagick has no way to automagically determine the image format
so we explicitly set one:
</p>
-<pre class="highlight"><code>magick -size 640x480 -depth 8 rgb:image image.png</code></pre>
+<ul><pre class="bg-light text-dark"><samp>magick -size 640x480 -depth 8 rgb:image image.png</samp></pre></ul>
-<h5>Built-in Images and Patterns</h5>
+<h4>Built-in Images and Patterns</h4>
<p>ImageMagick has a number of built-in <a href="formats.html#builtin-images">images</a> and <a href="formats.html#builtin-patterns">patterns</a>. To utilize the checkerboard pattern, for example, use:
</p>
-<pre class="highlight"><code>magick -size 640x480 pattern:checkerboard checkerboard.png</code></pre>
+<ul><pre class="bg-light text-dark"><samp>magick -size 640x480 pattern:checkerboard checkerboard.png</samp></pre></ul>
-<h5>STDIN, STDOUT, and file descriptors</h5>
-<p>Unix and Windows permit the output of one command to be piped to the input of another. ImageMagick permits image data to be read and written from the <a href="http://en.wikipedia.org/wiki/Standard_streams">standard streams</a> STDIN (<var>standard in</var>) and STDOUT (<var>standard out</var>), respectively, using a pseudo-filename of <code>-</code>. In this example we pipe the output of
+<h4>STDIN, STDOUT, and file descriptors</h4>
+<p>Linux and Windows permit the output of one command to be piped to the input of another. ImageMagick permits image data to be read and written from the <a href="http://en.wikipedia.org/wiki/Standard_streams">standard streams</a> STDIN (<var>standard in</var>) and STDOUT (<var>standard out</var>), respectively, using a pseudo-filename of <samp>-</samp>. In this example we pipe the output of
<a href="magick.html">magick</a> to the <a href="display.html">display</a> program:
</p>
-<pre class="highlight"><code>magick logo: gif:- | display gif:-</code></pre>
+<ul><pre class="bg-light text-dark"><samp>magick logo: gif:- | magick display gif:-</samp></pre></ul>
-<p>The second explicit format "<code>gif:</code>" is optional in the preceding example. The GIF image format has a unique signature within the image so ImageMagick's <a href="display.html">display</a> command can readily recognize the format as GIF. The <a href="magick.html">magick</a> program also accepts STDIN as input in this way:
+<p>The second explicit format "<samp>gif:</samp>" is optional in the preceding example.

(The pseudonyms <code>fd:0</code> and <code>fd:1</code> can be used for STDIN and STDOUT.) The next example shows how to append image data piped from files with descriptors 3 and 4 and direct the result to the file with descriptor number 5.

+<ul><pre class="bg-light text-dark"><samp>magick gif:fd:3 jpg:fd:4 -append tif:fd:5</samp></pre></ul>
-<h5>Selecting Frames</h5>
+<h4>Selecting Frames</h4>
<p>Some images formats contain more than one image frame. Perhaps you only want the first image, or the last, or some number of images in-between. You can specify which image frames to read by appending the image filename with the frame range enclosed in brackets. Here our image (an animated GIF) contains more than one frame but we only want the first:
</p>
-<pre class="highlight"><code>magick 'images.gif[0]' image.png</code></pre>
+<ul><pre class="bg-light text-dark"><samp>magick 'images.gif[0]' image.png</samp></pre></ul>
-<p class="text-info">Unix shells generally interpret brackets so we enclosed the filename in quotes above.
-In a Windows command shell the brackets are not interpreted but using quotes doesn't hurt. However, in most cases the roles of single-quotes and double-quotes are reversed with respect to Unix and Windows, so Windows users should usually try double-quotes where we display single-quotes, and vice versa.
+<p class="text-info">Linux shells generally interpret brackets so we enclosed the filename in quotes above.

However, in most cases the roles of single-quotes and double-quotes are reversed with respect to Linux and Windows, so Windows users should usually try double-quotes where we display single-quotes, and vice versa.
</p>
<p>You can read more than one image from a sequence with a frame range. For example, you can extract the first four frames of an image sequence:
</p>
-<pre class="highlight"><code>magick 'images.gif[0-3]' images.mng</code></pre>
+<ul><pre class="bg-light text-dark"><samp>magick 'images.gif[0-3]' images.mng</samp></pre></ul>
-<p>The default is to step one frame at a time so frames 0, 1, 2, and 3 are returned. Set the step to 2 with <code>-define frames:step=2</code> and we instead get frames 0 and 2.</p>
+<p>The default is to step one frame at a time so frames 0, 1, 2, and 3 are returned. Set the step to 2 with <samp>-define frames:step=2</samp> and we instead get frames 0 and 2.</p>
<p>Finally, you can read more than one image from a sequence, out-of-order. The next command gets the third image in the sequence, followed by the second, and then the fourth:
</p>
-<pre class="highlight"><code>magick 'images.gif[3,2,4]' images.mng</code></pre>
+<ul><pre class="bg-light text-dark"><samp>magick 'images.gif[3,2,4]' images.mng</samp></pre></ul>
<p>Notice that in the last two commands, a single image is written. The output in this case, where the image type is MNG, is a multi-frame file because the MNG format supports multiple frames. Had the output format been JPG, which only supports single frames, the output would have consisted of separate frames. More about that below, in the section about the <a href="command-line-processing.html#output">Output Filename</a>.
</p>
-<h5>Selecting an Image Region</h5>
+<h4>Selecting an Image Region</h4>
<p>Raw images are a sequence of color intensities without additional meta information such as width, height, or image signature. With raw image formats, you must specify the image width and height but you can also specify a region of the image to read. In our example, the image is in the raw 8-bit RGB format and is 6000 pixels wide and 4000 pixels high. However, we only want a region of 600 by 400 near the center of the image:
</p>
-<pre class="highlight"><code>magick -size 6000x4000 -depth 8 'rgb:image[600x400+1900+2900]' image.jpg</code></pre>
+<ul><pre class="bg-light text-dark"><samp>magick -size 6000x4000 -depth 8 'rgb:image[600x400+1900+2900]' image.jpg</samp></pre></ul>
<p>
You can get the same results with the <a class="text-nowrap" href="command-line-options.html#extract">-extract</a> option:
</p>
-<pre class="highlight"><code>magick -size 6000x4000 -depth 8 -extract 600x400+1900+2900 rgb:image image.jpg</code></pre>
+<ul><pre class="bg-light text-dark"><samp>magick -size 6000x4000 -depth 8 -extract 600x400+1900+2900 rgb:image image.jpg</samp></pre></ul>
-<h5>Inline Image Resize</h5>
+<h4>Inline Image Resize</h4>
<p>It is sometimes convenient to resize an image as they are read. Suppose you have hundreds of large JPEG images you want to convert to a sequence of PNG thumbails:
</p>
-<pre class="highlight"><code>magick '*.jpg' -resize 120x120 thumbnail%03d.png</code></pre>
+<ul><pre class="bg-light text-dark"><samp>magick '*.jpg' -resize 120x120 thumbnail%03d.png</samp></pre></ul>
<p>Here <var>all</var> the images are read and subsequently
resized. It is faster and less resource intensive to resize each image as it
is read:
</p>
-<pre class="highlight"><code>magick '*.jpg[120x120]' thumbnail%03d.png</code></pre>
+<ul><pre class="bg-light text-dark"><samp>magick '*.jpg[120x120]' thumbnail%03d.png</samp></pre></ul>
-<h5>Inline Image Crop</h5>
+<h4>Inline Image Crop</h4>
<p>It is sometimes convenient to crop an image as they are read. Suppose you have hundreds of large JPEG images you want to convert to a sequence of PNG thumbails:
</p>
-<pre class="highlight"><code>magick '*.jpg' -crop 120x120+10+5 thumbnail%03d.png</code></pre>
+<ul><pre class="bg-light text-dark"><samp>magick '*.jpg' -crop 120x120+10+5 thumbnail%03d.png</samp></pre></ul>

<h1 class="text-center">Distributed Pixel Cache</h1>
<p class="lead magick-description">A distributed pixel cache is an extension of the traditional pixel cache available on a single host. The distributed pixel cache may span multiple servers so that it can grow in size and transactional capacity to support very large images or large image sequences. Start up the pixel cache server on one or more hosts. When you read or operate on an image and the local pixel cache resources are exhausted, ImageMagick contacts one or more of these remote pixel servers to store or retrieve pixels.</p>
-<p>For really large images or large image sequences, or if there is limited resources on your host, you can utilize a distributed pixel cache on one or more remote hosts. To get started, first set your shared secret in the <code>policy.xml</code> security policy configuration file:</p>
-<pre class="highlight">
-<policy domain="cache" name="shared-secret" value="<em>passhrase</em>" stealth="true"/>

+<p>For really large images or large image sequences, or if there is limited resources on your host, you can utilize a distributed pixel cache on one or more remote hosts. To get started, first set your shared secret in the <samp>policy.xml</samp> security policy configuration file:</p>
+<ul><pre class="bg-light text-dark"><samp>
+<policy domain="cache" name="shared-secret" value="<em>passhrase</em>" stealth="true"/> </samp></pre></ul>
<p>Here we create two distributed pixel caches and utilize them from our desktop:</p>
-<pre class="highlight"><code>magick -distribute-cache 6668 & # start on 192.168.100.50
+<ul><pre class="bg-light text-dark"><samp>magick -distribute-cache 6668 & # start on 192.168.100.50
magick -distribute-cache 6668 & # start on 192.168.100.51
magick -limit memory 1GiB -limit map 2GiB -limit disk 4GiB \
-define registry:cache:hosts=192.168.100.50:6668,192.168.100.51:6668 \
- myhugeimage.jpg -sharpen 5x2 myhugeimage.png
-</code></pre>
+ myhugeimage.jpg -sharpen 5x2 myhugeimage.png </samp></pre></ul>
<p>For large image sequences, the servers are contacted in a round-robin fashion to distribute the load over multiple distributed pixel caches (assuming you have a host list rather than a single host). In our example, some modest resources are available on the desktop as defined by the -limit option. For smaller images, they are allocated on the desktop up to the specified limits.</p>
<p>Your image processing tasks are likely to perform slower when utilizing a distributed pixel cache due to pixels shuffling between the client and the server over a network. Algorithms that access virtual pixels (e.g. -sharpen) are noticeably slower, up to 3 times slower, than algorithms that only access authentic pixels (e.g. -negate) due to increased network traffic.</p>
<p>A client can only contact a compatible distributed pixel cache server. Compatibility requires the same ImageMagick library interface, quantum depth, HDRI status, OS word size, and endianness. The distributed pixel cache checks these attributes and exits if these requirements are not met.</p>

<p>In 1990 there were few freely available image processing tools so I expected an enthusiastic reception. Before a release was possible, Dr. Pensak had to convince upper management at DuPont to give away what they might perceive as valuable intellectual property. I suspect they agreed simply because ImageMagick was not chemically or biologically based, so they did not understand its value to the company. Either way, ImageMagick would not be available today without DuPont transferring the copyright to ImageMagick Studio LLC. ImageMagick was posted to Usenet's comp.archives group on August 1st, 1990.</p>

<p>Note, under Windows (and possibly the Mac) it may be necessary to initialize the ImageMagick library prior to using the Magick++ library. This initialization is performed by passing the path to the ImageMagick DLLs (assumed to be in the same directory as your program) to the InitializeMagick() function call. This is commonly performed by providing the path to your program (argv[0]) as shown in the following example: </p>

+<h1 class="text-center">MagickCache: an Efficient Image Cache</h1>
+<p class="text-info">The Magick cache is a work in progress. Do not use the cache in production services until version is at least 1.0.0. It is currently 0.9.2. The MagickCache requires ImageMagick version 7.1.0-0 or above.</p>
+<p class="lead magick-description">The MagickCache provides secure methods and tools to cache images, image sequences, video, audio or metadata in a local folder. Any content is memory-mapped for efficient retrieval. Additional efficiencies are possible by retrieving a portion of an image. Content can persist or you can assign a time-to-live (TTL) to automatically expire content when the TTL is exceeded. MagickCache supports virtually unlimited content upwards of billions of images making it suitable as a web image service.</p>
+<p>The MagickCache works in concert with <a href="https://imagemagick.org">ImageMagick</a>. Download the <a href="https://github.com/ImageMagick/MagickCache">MagickCache</a> and install. You will now want to create the cache and populate it with images, video, and associated metadata.</p>
+<h4>Create a MagickCache</h4>
+<p>You will require a place to store and retrieve your content. Let's create a cache on our local filesystem:</p>
+<ul><pre class="bg-light text-dark"><samp>$ magick-cache -passkey passkey.txt create /opt/magick-cache</samp></pre></ul>
+<p>Where `passkey.txt` contains your cache passkey. Don't lose your passkey. Without it, you will be unable to identify, expire, or delete content in your cache.</p>
+<p>You only need to create a MagickCache once. You can, however, create more than one MagickCache with different paths.</p>
+<p>Once the MagickCache is created, you will want to populate the cache with content that includes images, video, audio, or metadata.
+<h4>Put content in the MagickCache</h4>
+<p>Let's add a movie cast image to our newly created cache:</p>
+<ul><pre class="bg-light text-dark"><samp>$ magick-cache put /opt/magick-cache movies/images/mission-impossible/cast/rebecca-ferguson 20210508-rebecca-ferguson.jpg</samp></pre></ul>
+<p>Note, the image identifier is an IRI composed of <em>project</em>/<em>type</em>/<em>resource-path</em>. In this example, the project is <samp>movies</samp>, type is <samp>image</samp>, and the resource path is <samp>mission-impossible/cast/rebecca-ferguson</samp>. The path uniquely identifies a cache resource. Two different images cannot be stored with the same resource path. Instead use something like <samp>mission-impossible/cast/20210508-rebecca-ferguson-1</samp> and <samp>mission-impossible/cast/20210508-rebecca-ferguson-2</samp>.</p>
+<p>Now, let's set a resource passkey and the time to live to 2 days. Anytime after the second day, the image is automatically deleted with the <samp>expire</samp> function. To get, expire, or delete the image, you will need to use the same resource passkey:</p>
+<ul><pre class="bg-light text-dark"><samp>$ magick-cache -passkey passkey.txt -ttl "2 days" put /opt/magick-cache movies/images/mission-impossible/cast/rebecca-ferguson 20210508-rebecca-ferguson.jpg</samp></pre></ul>
+<p>Where <samp>passkey.txt</samp> contains your resource passkey. Don't lose your passkey. Without it, you will be unable to get, identify, expire or delete resources you own.</p>
+<p>The resource passkey ensures only you and the cache owner can access your image. To prevent the cache owner from viewing its content, scramble it with:</p>
+<ul><pre class="bg-light text-dark"><samp>$ magick-cache -passkey passkey.txt -passphrase passphrase.txt -ttl "2 days" put /opt/magick-cache movies/images/mission-impossible/cast/rebecca-ferguson 20210508-rebecca-ferguson.jpg</samp></pre></ul>
+<p>Note, blobs and metadata are stored in the cache in plaintext. To prevent snooping, scramble the content before you store it in the cache.</p>
+<h4>Get content from the MagickCache</h4>
+<p>Eventually you will want retrieve your content, let's get our original cast image from the cache:</p>
+<ul><pre class="bg-light text-dark"><samp>$ magick-cache -passkey passkey.txt get /opt/magick-cache movies/images/mission-impossible/cast/rebecca-ferguson rebecca-ferguson.png</samp></pre></ul>
+<p>Notice the original image was put in the cache in the JPEG format. Here we conveniently convert it to the PNG format as we extract the image.</p>
+<p>The <samp>-extract</samp> option is useful when retrieving an image. To extract a portion of the image, specify tile width, height, and offset:</p>
+
+<ul><pre class="bg-light text-dark"><samp>$ magick-cache -passkey passkey.txt -extract 100x100+0+0 get /opt/magick-cache movies/images/mission-impossible/cast/rebecca-ferguson rebecca-ferguson.png</samp></pre></ul>
+<p>To resize instead, do not specify the offset:</p>
+
+<ul><pre class="bg-light text-dark"><samp>$ magick-cache -passkey passkey.txt -extract 100x100 get /opt/magick-cache movies/images/mission-impossible/cast/rebecca-ferguson rebecca-ferguson.png</samp></pre></ul>
+
+<p>If your image is scrambled, provide the passphrase to descramble it:</p>
+
+<ul><pre class="bg-light text-dark"><samp>$ magick-cache -passkey passkey.txt -passphrase passphrase.txt get /opt/magick-cache movies/images/mission-impossible/cast/rebecca-ferguson rebecca-ferguson.png</samp></pre></ul>
+
+<h4>Delete content from the MagickCache</h4>
+<p>We can explicitly delete content:</p>
+<ul><pre class="bg-light text-dark"><samp>$ magick-cache -passkey passkey.txt delete /opt/magick-cache movies/images/mission-impossible/cast/rebecca-ferguson</samp></pre></ul>
+<p>or we can delete all cast images that have expired (exceeded their respective time to live), try this comand:</p>
+<ul><pre class="bg-light text-dark"><samp>$ magick-cache -passkey passkey.txt expire /opt/magick-cache movies/images/mission-impossible/cast</samp></pre></ul>
+<h4>Identify the MagickCache content</h4>
+<p>Perhaps you want to identify all the content you own:</p>
+<ul><pre class="bg-light text-dark"><samp>$ magick-cache -passkey passkey.txt identify /opt/magick-cache movies/images/mission-impossible/cast
+movies/images/mission-impossible/cast/rebecca-ferguson[1368x912] 406B 1:0:0:0 2021-05-30T17:41:42Z
+identified 1 resources</samp></pre></ul>
+<p>Each entry includes the IRI, image dimensions for images, the content extent in bytes, time to live, whether the resource is expired (denoted with a `*`), and the creation date.</p>
+<p>Others can store content in the cache along side your content. However, their content is unavailable to you. You cannot get, identify, expire or delete content that you do not own as determined by your secret passkey.</p>
+<p>The MagickCache owner can get, identify, expire, or delete all the content, including content you own, with this command, for example:</p>
+<ul><pre class="bg-light text-dark"><samp>$ magick-cache -passkey passkey.txt identify /opt/magick-cache /</samp></pre></ul>
+<p>Note, expired reesources are annotated with an asterisks.</p>
+<h4>MagickCache is not just for Images</h4>
+<p>In addition to a type of <samp>image</samp>, you can store the image content in its original form, video, or audio as content type of <samp>blob</samp> or metadata with a content type of <samp>meta</samp>:</p>
+<ul><pre class="bg-light text-dark"><samp>$ magick-cache -passkey passkey.txt put /opt/magick-cache movies/blob/mission-impossible/cast/rebecca-ferguson 20210508-rebecca-ferguson.mp4</samp></pre></ul>
+<p> or</p>
+<ul><pre class="bg-light text-dark"><samp>$ magick-cache -passkey passkey.txt put /opt/magick-cache movies/meta/mission-impossible/cast/rebecca-ferguson 20210508-rebecca-ferguson.txt</samp></pre></ul>
+<p>Images must be in a format that ImageMagick understands. Metadata must be text. Blobs can be any content including images, video, audio, or binary files.</p>
+<h4>Delete a MagickCache</h4>
+<p>The MagickCache owner can completely delete all the content within a cache:</p>
+<ul><pre class="bg-light text-dark"><samp>$ magick-cache -passkey passkey.txt delete /opt/magick-cache /</samp></pre></ul>
+<p>Be careful, after this command, your cached content is irrevocably lost.</p>
+<h4>Security</h4>
+<p>MagickCache security is not crytographically strong. Instead it generates a unique hash for each resource ensuring the resource ID cannot be discovered. A resource is accessible to both the user of the cache and the cache owner provided they can present their respective passkeys. They are also accessible to anyone with sufficient privileges to access the MagickCache disk path.</p>

-<h5>Ashlar Pseudo-image Format</h5>
+<h4>Ashlar Pseudo-image Format</h4>
<p>Use the Ashlar pseudo-image format to lay out an image sequence in continuous irregular courses. By default, a reasonable canvas size and border width is determined relative to the image collection you provide. You can explicitedly set the canvas size and border width by appending to the filename, e.g. ashlar:canvas.png[1024x768+4+4]. By default, alignment is along the left edge. Use -define ashlar:best-fit=true to align on both the left and right edges. You can label the image tiles with, for example, -label %f. Here is an example command:
-<pre class="highlight"><code>magick '*.png' -resize 320x320 -label %f ashlar:ashlar.png</code></pre>
-<p>This is designed to quickly view a collection of images. To have more control over the layout of your image tiles, use the <code>montage</code> command instead.</p>

<h1 class="text-center">Threads of Execution</h1>
<p class="lead magick-description">Many of ImageMagick's internal algorithms are threaded to take advantage of speed-ups offered by the multicore processor chips and <a href="http://www.openmp.org">OpenMP</a>. OpenMP, is an API specification for parallel programming. If your compiler supports OpenMP (e.g. gcc, Visual Studio 2005) directives, ImageMagick automatically includes support. To verify, look for the OpenMP feature of ImageMagick with this command:</p>
-<pre class="highlight"><code>-> magick identify -version
+<ul><pre class="bg-light text-dark"><samp>$ magick identify -version

-Features: OpenMP(4.5)</code></pre>
+Features: OpenMP(4.5)</samp></pre></ul>
<p>With OpenMP enabled, most ImageMagick algorithms execute on all the cores on your system in parallel. ImageMagick typically divides the work so that each thread processes 64 rows of pixels. As rows are completed, OpenMP assigns more chunks of pixel rows to each thread until the algorithm completes. For example, if you have a quad-core system, and attempt to resize an image, the resizing takes place on 4 cores (8 if hyperthreading is enabled).</p>
-<p>You can further increase performance by reducing lock contention with the <a href="http://goog-perftools.sourceforge.net/doc/tcmalloc.html">tcmalloc</a> memory allocation library. To enable, add <code>--with-tcmalloc</code> to the <code>configure</code> command-line when you build ImageMagick.</p>

+<h4>The Perils of Parallel Execution</h4>
<p>It can be difficult to predict behavior in a parallel environment. Performance might depend on a number of factors including the compiler, the version of the OpenMP library, the processor type, the number of cores, the amount of memory, whether hyperthreading is enabled, the mix of applications that are executing concurrently with ImageMagick, or the particular image-processing algorithm you utilize. The only way to be certain of the optimal performance, in terms of the number of threads, is to benchmark. ImageMagick includes progressive threading when benchmarking a command and returns the elapsed time and efficiency for one or more threads. This can help you identify how many threads are the most efficient in your environment. Here is an example benchmark for threads 1-8:</p>

<h2><a class="anchor" id="channels"></a>Pixel Channels</h2>
<p>A pixel is comprised of one or more color values, or <var>channels</var> (e.g. red pixel channel).</p>
<p>Prior versions of ImageMagick (4-6), support 4 to 5 pixel channels (RGBA or CMYKA). The first 4 channels are accessed with the PixelPacket data structure. The structure includes 4 members of type Quantum (typically 16-bits) of red, green, blue, and opacity. The black channel or colormap indexes are supported by a separate method and structure, IndexPacket. As an example, here is a code snippet from ImageMagick version 6 that negates the color components (but not the alpha component) of the image pixels:</p>

+<h4>Pixel User Channels</h4>
<p>In version 7, we introduce pixel user channels. Traditionally we utilize 4 channels, red, green, blue, and alpha. For CMYK we also have a black channel. User channels are designed to contain whatever additional channel information that makes sense for your application. Some examples include extra channels in TIFF or PSD images or perhaps you require a channel with infrared information for the pixel. You can associate traits with the user channels so that when they are acted upon by an image processing algorithm (e.g. blur) the pixels are copied, acted upon by the algorithm, or even blended with the alpha channel if that makes sense.</p>
-<h5>Pixel Metacontent</h5>
+<h4>Pixel Metacontent</h4>
<p>In version 7, we introduce pixel metacontent. Metacontent is content about content. So rather than being the content itself, it's something that describes or is associated with the content. Here the content is a pixel. The pixel metacontent is for your exclusive use (internally the data is just copied, it is not modified) and is accessed with these MagickCore API methods:</p>

A value of <code>QuantumRange</code> means that the pixel is opaque because the geometry completely overlapped the pixel. As a consequence, in version 7, the PixelInfo structure member alpha has replaced the previous opacity member. Another consequence is the alpha part of an sRGB value in hexadecimal notation is now reversed (e.g. #0000 is fully transparent).</p>

<h2><a class="anchor" id="mask"></a>Masks</h2>
-<p>Version 7 supports masks for most image operators. White pixels in a read mask ignores corresponding pixel in an image whereas white pixels in a write mask protects the corresponding pixel in the image. From the command-line, you can associate a mask with an image with the <code>-read-mask</code> and <code>-write-mask</code> options. This polarity matches the masks in version 6 of ImageMagick for ease of porting your workflow. For convenience, we continue to support the <code>-mask</code> option in version 7 to match the behavior of version 6.</p>

The policy is open by default. This affords maximum utility for ImageMagick installations that run in a sandboxed environment, perhaps in a Docker instance, or behind a firewall where security risks are greatly diminished as opposed to a public website.</p>
<p>Security is a trade-off between a secure environment and convenience. If you want ImageMagick to be optimally secure, you could, for example, limit ImageMagick to only read or write web safe images (e.g. GIF, JPEG, PNG). However, ImageMagick provides for a more secure option by adjusting the security policy per the requirements of your local environment or organizational policies. The security policy covers areas such as memory, which paths to read or write, how many images are permitted in an image sequence, how long a workflow can run, how much disk the image pixels can consume, a secret passphrase for remote connections, which coders are permitted or denied, and others. These policies should provide robust coverage to not only secure your environment per your requirements but also ensure ImageMagick remains a good citizen (e.g. prevent thrashing with large images) in your local environment.</p>
-<p>As an example, suppose you download an image from the internet and unbeknownst to you its been crafted to generate a 20000 by 20000 pixel image. ImageMagick attempts to allocate enough resources (memory, disk) and your system will likely deny the resource request and exit. However, its also possible that your computer might be temporarily sluggish or unavailable or ImageMagick may abort. To prevent such a scenario, you can set limits in the <a href="https://imagemagick.org/source/policy.xml">policy.xml</a> configuration file. You might wonder why ImageMagick does not already include reasonable limits? Simply because what is reasonable in your environment, might not be reasonable to someone else. For example, you may have ImageMagick sandboxed where security is not a concern, whereas another user may use ImageMagick to process images on their publically accessible website. Or ImageMagick runs on a host with 1TB of memory whereas another ImageMagick instance runs on an mobile phone. By policy, permitting giga-pixel image processing on the large memory host makes sense, not so much for the resource constrained mobile phone. If you utilize ImageMagick from a public website, you may want to increase security by preventing usage of the MVG or HTTPS coders. Only you can decide what are reasonable limits taking in consideration your environment. We provide this policy with reasonable limits and encourage you to modify it to suit your local environment:</p>

<p>As of ImageMagick 7.0.7-0, you can allocate the pixel cache and some internal buffers with anonymous memory mapping rather than from heap. As a consequence, the pixels are initialized to zero resulting in a minor performance penalty. You can also securely delete any temporary files for increased security. The value is the number of times to shred (replace its content with random data) before deleting a temporary file. For example,</p>
-<pre class="highlight"><code><policy domain="system" name="memory-map" value="anonymous"/>

<p>Some image processing algorithms (e.g. wavelet transform) might consume a substantial amount of memory to complete. ImageMagick maintains a separate memory pool for these large resource requests and as of 7.0.6-1 permits you to set a maximum request limit. If the limit is exceeded, the allocation is instead memory-mapped on disk. Here we limit the maximum memory request by policy:</p>
-<pre class="highlight"><code><policy domain="system" name="max-memory-request" value="256MiB"/> </code></pre>
+<ul><pre class="bg-light text-dark"><samp><policy domain="system" name="max-memory-request" value="256MiB"/> </samp></pre></ul>
<p>As of ImageMagick version 7.0.4-23, you can limit the maximum number of images in a sequence. For example, to limit an image sequence to at most 64 frames, use:</p>
-<pre class="highlight"><code><policy domain="resource" name="list-length" value="64"/></code></pre>
+<ul><pre class="bg-light text-dark"><samp><policy domain="resource" name="list-length" value="64"/></samp></pre></ul>
<p>For additional details about resource limits and the policy configuration file, read <a href="../www/resources.html">Resources</a> and <a href="../www/architecture.html">Architecture</a>.</p>
<p>As of ImageMagick 7.0.6-0, you can programmatically set the ImageMagick security policy with SetMagickSecurityPolicy() (MagickCore) or MagickSetSecurityPolicy() (MagickWand).</p>
<p>As of ImageMagick version 7.0.8-11, you can set a module security policy. For example, to prevent Postscript or PDF interpretation, use:</p>
-<pre class="highlight"><code><policy domain="module" rights="none" pattern="{ps,pdf,xps}/></code></pre>
+<ul><pre class="bg-light text-dark"><samp><policy domain="module" rights="none" pattern="{ps,pdf,xps}/></samp></pre></ul>
<p>As of ImageMagick version 7.0-10-52, you can set a font policy. Specify a path to a Unicode font that ImageMagick defaults to whenever the user does not specify a font preference:</p>
-<pre class="highlight"><code><policy domain="system" name="font" value="/usr/share/fonts/arial-unicode.ttf"/></code></pre>

<h2><a class="anchor" id="synchronize"></a>Pixel Cache Synchronize Policy</h2>
<p>When writing image pixels to disk, ImageMagick firsts preallocates the disk file, which is much faster than fully populating the file with zeros. To further increase performance, we memory-map the file on disk. With memory-mapping, we get an increase in performance (up to 5x), however, there remains a possibility that as the disk file is populated, it may run out of free space. The OS then throws a SIGBUS signal which prevents ImageMagick from continuing. To prevent a SIGBUS, use this security policy:
-<pre class="highlight">
+<ul><pre class="bg-light text-dark">
<policy domain="cache" name="synchronize" value="True"/>
-</pre>
+</pre></ul>
<p>Set to True to ensure all image data is fully flushed and synchronized to disk. There is a performance penalty, however, the benefits include ensuring a valid image file in the event of a system crash and early reporting if there is not enough disk space for the image pixel cache.</p>
