18 <meta name="Description" content="ImageMagick® is a software suite to create, edit, and compose bitmap images. It can read, convert and write images in a variety of formats (about 100) including GIF, JPEG, JPEG-2000, PNG, PDF, PhotoCD, TIFF, and DPX. Use ImageMagick to translate, flip, mirror, rotate, scale, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves. ImageMagick is free software delivered as a ready-to-run binary distribution or as source code that you can freely use, copy, modify, and distribute. Its license is compatible with the GPL. It runs on all major operating systems. The functionality of ImageMagick is typically utilized from the command line or you can use the features from programs written in your favorite programming language. Choose from these interfaces: MagickCore (C), MagickWand (C), ChMagick (Ch), Magick++ (C++), JMagick (Java), L-Magick (Lisp), PascalMagick (Pascal), PerlMagick (Perl), MagickWand for PHP (PHP), PythonMagick (Python), RMagick (Ruby), or TclMagick (Tcl/TK). With a language interface, use ImageMagick to modify or create images automagically and dynamically."/>

3819 <p>MagickOrderedPosterizeImage() performs an ordered dither based on a number of pre-defined dithering threshold maps, but over multiple intensity levels, which can be different for different channels, according to the input arguments.</p></ol>
3821 <p>The format of the MagickOrderedPosterizeImage method is:</p>
3824 MagickBooleanType MagickOrderedPosterizeImage(MagickWand *wand,
3825 const char *threshold_map)
3826 MagickBooleanType MagickOrderedPosterizeImageChannel(MagickWand *wand,
3827 const ChannelType channel,const char *threshold_map)
3830 <p>A description of each parameter follows:</p></ol>
3833 <ol><p>the image.</p></ol>
3836 <ol><p>the channel or channels to be thresholded.</p></ol>
3838 <h5>threshold_map</h5>
3839 <ol><p>A string containing the name of the threshold dither map to use, followed by zero or more numbers representing the number of color levels tho dither between.</p></ol>
3841 <p>Any level number less than 2 is equivelent to 2, and means only binary dithering will be applied to each color channel.</p></ol>
3843 <p>No numbers also means a 2 level (bitmap) dither will be applied to all channels, while a single number is the number of levels applied to each channel in sequence. More numbers will be applied in turn to each of the color channels.</p></ol>
3845 <p>For example: "o3x3,6" generates a 6 level posterization of the image with a ordered 3x3 diffused pixel dither being applied between each level. While checker,8,8,4 will produce a 332 colormaped image with only a single checkerboard hash pattern (50 grey) between each color level, to basically double the number of color levels with a bare minimim of dithering.</p></ol>
