The fundamental principle of the Hald CLUT algorithm is that application of an identity CLUT causes no change to the input image, but an identity CLUT image which has had its colors transformed in some way (e.g. in Adobe Photoshop) may be used to implement an identical transform on any other image.</p> <p>The minimum CLUT level is 2, and the maximum depends on available memory (largest successfully tested is 24). A CLUT image is required to have equal width and height. A CLUT of level 8 is an image of dimension 512x512, a CLUT of level 16 is an image of dimension 4096x4096. Interpolation is used so extremely large CLUT images are not required.</p> <p>GraphicsMagick provides an 'identity' coder which may be used to generate identity HLUTs. For example, reading from "identity:8" creates an identity CLUT of order 8.</p> <p>The Hald CLUT algorithm has been developed by Eskil Steenberg as described at <a class="reference external" href="http://www.quelsolaar.com/technology/clut.html">http://www.quelsolaar.com/technology/clut.html</a>, and was adapted for GraphicsMagick by Clément Follet with support from Cédric Lejeune of Workflowers.</p> <p>The format of the HaldClutImage method is:</p> <pre class="literal-block"> MagickPassFail MagickHaldClutImage( MagickWand *wand, const MagickWand *clut_wand ); </pre> <p>A description of each parameter follows:</p> <dl class="docutils"> <dt>wand:</dt> <dd>The image wand.</dd> <dt>clut_wand:</dt> <dd>The color lookup table image wand</dd> </dl> </div> </div> <div class="section" id="magickhascolormap"> <h1><a class="toc-backref" href="#id583">MagickHasColormap</a></h1> <div class="section" id="id219"> <h2>Synopsis</h2> <pre class="literal-block"> unsigned int MagickHasColormap( MagickWand *wand, unsigned int *colormap ); </pre> </div> <div class="section" id="id220"> <h2>Description</h2> <p>MagickHasColormap() returns True if the check was successful with the colormap parameter set to a boolean value indicating whether the current wand image uses a color map or not.

The default quality is 75. Use the -sampling-factor option to specify the factors for chroma downsampling. To use the same quality value as that found by the JPEG decoder, use the -define jpeg:preserve-settings flag.</p> <p>For the MIFF image format, and the TIFF format while using ZIP compression, quality/10 is the zlib compres- sion level, which is 0 (worst but fastest compression) to 9 (best but slowest). It has no effect on the image appearance, since the compression is always lossless.</p> <p>For the JPEG-2000 image format, quality is mapped using a non-linear equation to the compression ratio required by the Jasper library. This non-linear equation is intended to loosely approximate the quality provided by the JPEG v1 format. The default quality value 75 results in a request for 16:1 compression. The quality value 100 results in a request for non-lossy compres- sion.</p> <p>For the MNG and PNG image formats, the quality value sets the zlib compression level (quality / 10) and filter-type (quality % 10). Compression levels range from 0 (fastest compression) to 100 (best but slowest). For compression level 0, the Huffman-only strategy is used, which is fastest but not necessarily the worst compression. If filter-type is 4 or less, the specified filter-type is used for all scanlines:</p> <ol class="arabic simple" start="0"> <li>none</li> <li>sub</li> <li>up</li> <li>average</li> <li>Paeth</li> </ol> <p>If filter-type is 5, adaptive filtering is used when quality is greater than 50 and the image does not have a color map, otherwise no filtering is used.</p> <p>If filter-type is 6, adaptive filtering with minimum- sum-of-absolute-values is used.</p> <p>Only if the output is MNG, if filter-type is 7, the LOCO color transformation and adaptive filtering with minimum-sum-of-absolute-values are used.</p> <p>The default is quality is 75, which means nearly the best compression with adaptive filtering. The quality setting has no effect on the appearance of PNG and MNG images, since the compression is always lossless.</p> <p>For further information, see the PNG specification.</p> <p>When writing a JNG image with transparency, two quality values are required, one for the main image and one for the grayscale image that conveys the opacity channel. These are written as a single integer equal to the main image quality plus 1000 times the opacity quality. For example, if you want to use quality 75 for the main image and quality 90 to compress the opacity data, use -quality 90075.</p> <p>For the PNM family of formats (PNM, PGM, and PPM) specify a quality factor of zero in order to obtain the ASCII variant of the format. Note that -compress none used to be used to trigger ASCII output but provided the opposite result of what was expected as compared with other formats.</p> <p>The format of the MagickSetCompressionQuality method is:</p> <pre class="literal-block"> unsigned int MagickSetCompressionQuality( MagickWand *wand, const unsigned long quality ); </pre> <dl class="docutils"> <dt>wand:</dt> <dd>The magick wand.</dd> <dt>delay:</dt> <dd>The image quality.</dd> </dl> </div> </div> <div class="section" id="magicksetdepth"> <h1><a class="toc-backref" href="#id638">MagickSetDepth</a></h1> <div class="section" id="id329"> <h2>Synopsis</h2> <pre class="literal-block"> unsigned int MagickSetDepth( MagickWand *wand, const size_t depth ); </pre> </div> <div class="section" id="id330"> <h2>Description</h2> <p>MagickSetDepth() sets the sample depth to be used when reading from a raw image or a format which requires that the depth be specified in advance by the user.</p> <p>The format of the MagickSetDepth method is:</p> <pre class="literal-block"> unsigned int MagickSetDepth( MagickWand *wand, const size_t depth ); </pre> <p>A description of each parameter follows:</p> <dl class="docutils"> <dt>wand:</dt> <dd>The magick wand.</dd> <dt>depth:</dt> <dd>The sample depth.</dd> </dl> </div> </div> <div class="section" id="magicksetfilename"> <h1><a class="toc-backref" href="#id639">MagickSetFilename</a></h1> <div class="section" id="id331"> <h2>Synopsis</h2> <pre class="literal-block"> unsigned int MagickSetFilename( MagickWand *wand, const char *filename ); </pre> </div> <div class="section" id="id332"> <h2>Description</h2> <p>MagickSetFilename() sets the filename before you read or write an image file.</p> <p>The format of the MagickSetFilename method is:</p> <pre class="literal-block"> unsigned int MagickSetFilename( MagickWand *wand, const char *filename ); </pre> <p>A description of each parameter follows:</p> <dl class="docutils"> <dt>wand:</dt> <dd>The magick wand.</dd> <dt>filename:</dt> <dd>The image filename.</dd> </dl> </div> </div> <div class="section" id="magicksetformat"> <h1><a class="toc-backref" href="#id640">MagickSetFormat</a></h1> <div class="section" id="id333"> <h2>Synopsis</h2> <pre class="literal-block"> unsigned int MagickSetFormat( MagickWand *wand, const char *format ); </pre> </div> <div class="section" id="id334"> <h2>Description</h2> <p>MagickSetFormat() sets the file or blob format (e.g. "BMP") to be used when a file or blob is read.
