- <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."/>

+<h1>ImageMagick JPEG-2000 Image Format</h1>
<p class="navigation-index"></p>
<p>ImageMagick's JPEG-2000 image formats, JP2 and JPC, accept a plethora of encoding options as detailed below. As an example, suppose you are interested in these options:</p>
<p>Use this command:</p>
-<p class='crt'><span class="crtprompt"> $magick> </span><span class='crtin'>convert wizard.png -define jp2:cblkwidth=64 -define jp2:cblkheight=32 \ <br/>
+<p class="crt"><span class="crtprompt"> $ </span><span class="crtin">convert wizard.png -define jp2:cblkwidth=64 -define jp2:cblkheight=32 \ <br></br>
-define jp2:nomct -define jp2:numrlvls=4 -define jp2:rate=0.015625 wizard.jpc</span></p>
<p>Here we convert a giga-byte TIFF image to JPEG-2000 with a reduced memory footprint:</p>
-<p class='crt'><span class="crtprompt"> $magick> </span><span class='crtin'>convert frame-00038.tif -define jp2:tilewidth=256 -define jp2:tileheight=256 frame-00038.jp2</span></p>
+<p class="crt"><span class="crtprompt"> $ </span><span class="crtin">convert frame-00038.tif -define jp2:tilewidth=256 -define jp2:tileheight=256 frame-00038.jp2</span></p>
+<p>Here is a lossy example using the full gamut of JP2 options:</p>
+
+<p class="crt"><span class="crtprompt"> $ </span><span class="crtin">convert input.tif -define numrlvls=7 -define jp2:tilewidth=1024
+-define jp2:tileheight=1024 \<br></br>-define jp2:rate=0.02348 -define
+jp2:prg=rpcl -define jp2:mode=int -define jp2:prcwidth=16383 \<br></br>-define
+jp2:prcheight=16383 -define jp2:cblkwidth=64 -define jp2:cblkheight=64
+-define jp2:sop output.jp2</span></p>
+<p>Here is the same example with lossless encoding:</p>
+<p class="crt"><span class="crtprompt"> $ </span><span class="crtin">convert input.tif -define jp2:numrlvls=6 -define jp2:tilewidth=1024
+-define jp2:tileheight=1024 \<br></br>-define jp2:rate=1.0 -define jp2:lazy
+-define jp2:prg=rlcp -define jp2:ilyrrates=\<br></br>'0.015625,0.01858,0.0221,0.025,0.03125,0.03716,0.04419,0.05,0.0625,
+0.075,0.088,0.1,0.125,0.15,0.18,0.21,0.25,0.3,0.35,0.4,0.5,0.6,0.7,0.84'
+\<br></br>-define jp2:mode=int output.jp2</span></p>
<p>Here is a complete list of JPEG-2000 encoding options:</p>
<dl class="doc">
<dt class="doc">numgbits=n</dt>
<dd>Set the number of guard bits to n.</dd>
