<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>
-<pre><span class="crtprompt"> </span><span class='crtin'>cd ImageMagick-7.0.6-0</span><span class='crtout'></span><span class="crtprompt"> </span><span class='crtin'>./configure</span></pre>
+<pre><span class="crtprompt"> </span><span class='crtin'>cd ImageMagick-7.0.6-4</span><span class='crtout'></span><span class="crtprompt"> </span><span class='crtin'>./configure</span></pre>
<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>
<p><a href="download.html">Download</a> the ImageMagick source distribution and verify the distribution against its <a href="https://www.imagemagick.org/download/digest.rdf">message digest</a>.</p>

<p>Chances are the download, configure, build, and install of ImageMagick went flawlessly as it is intended, however, certain systems and environments may cause one or more steps to fail. We discuss a few problems we've run across and how to take corrective action to ensure you have a working release of 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 href="command-line-options.html#version">‑version</a> option: </p>
-<pre><span class="crtprompt"> </span><span class='crtin'>identify -version</span><span class='crtout'><br/></span><span class="crtprompt"> </span><span class='crtin'>Version: ImageMagick 7.0.6-0 2017-06-13 Q16 https://www.imagemagick.org</span></pre>

<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>
<h3><a id="authentic-pixels"></a>Access the Pixel Cache</h3>
<p>Here is a listing of a sample <a href="https://www.imagemagick.org/source/mgk.c">custom coder</a>. It reads and writes images in the MGK image format which is simply an ID followed by the image width and height followed by the RGB pixel values.</p>

<policy domain="cache" 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, an exception is thrown and the processing stops. Here we limit the maximum memory request by policy:</p>
+<pre><code><policy domain="system" name="max-memory-request" value="256MiB"/> </code></pre>
+
<p>You can verify your policy changes are in effect with this command:</p>
<pre class="pre-scrollable"><code>-> identify -list policy
