17 <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."/>

158 <div class="doc-section">
160 <p>CompositeImageChannel() returns the second image composited onto the first at the specified offset, using the specified composite method.</p></ol>
162 <p>The format of the CompositeImageChannel method is:</p>
165 MagickBooleanType CompositeImage(Image *image,
166 const CompositeOperator compose,Image *composite_image,
167 const long x_offset,const long y_offset)
168 MagickBooleanType CompositeImageChannel(Image *image,
169 const ChannelType channel,const CompositeOperator compose,
170 Image *composite_image,const long x_offset,const long y_offset)
173 <p>A description of each parameter follows:</p></ol>
176 <ol><p>the destination image, modified by he composition</p></ol>
179 <ol><p>the channel.</p></ol>
182 <ol><p>This operator affects how the composite is applied to the image. The operators and how they are utilized are listed here http://www.w3.org/TR/SVG12/#compositing.</p></ol>
184 <h5>composite_image</h5>
185 <ol><p>the composite (source) image.</p></ol>
188 <ol><p>the column offset of the composited image.</p></ol>
191 <ol><p>the row offset of the composited image.</p></ol>
193 <p>Extra Controls from Image meta-data in 'composite_image' (artifacts)</p></ol>
195 <p>o "compose:args" A string containing extra numerical arguments for specific compose methods, generally expressed as a 'geometry' or a comma separated list of numbers.</p></ol>
197 <p>Compose methods needing such arguments include "BlendCompositeOp" and "DisplaceCompositeOp".</p></ol>
199 <p>o "compose:outside-overlay" Modify how the composition is to effect areas not directly covered by the 'composite_image' at the offset given. Normally this is dependant on the 'compose' method, especially Duff-Porter methods.</p></ol>
201 <p>If set to "false" then disable all normal handling of pixels not covered by the composite_image. Typically used for repeated tiling of the composite_image by the calling API.</p></ol>
203 <p>Previous to IM v6.5.3-3 this was called "modify-outside-overlay"</p></ol>
