| <h1>Magick++ C++ API</h1> |
| <p class="navigation-index">[<a href="magick++.html#intro">Introduction to Magick++</a> • <a href="magick++.html#documentation">Documentation</a> • <a href="magick++.html#get">Obtaining Magick++</a> • <a href="magick++.html#install">Installation</a> • <a href="magick++.html#bugs">Reporting Bugs</a>]</p> |
| <div class="doc-section"> |
| <a id="intro"></a> |
| <p>Magick++ is the object-oriented C++ API to the <a href="http://www.imagemagick.org/">ImageMagick</a> image-processing library.</p> |
| <p>Magick++ supports an object model which is inspired by <a href="perl-magick.html">PerlMagick</a>. |
| Images support implicit reference counting so that copy constructors |
| and assignment incur almost no cost. The cost of actually copying an |
| image (if necessary) is done just before modification and this copy |
| is managed automagically by Magick++. De-referenced copies are |
| automagically deleted. The image objects support value (rather than |
| pointer) semantics so it is trivial to support multiple generations |
| of an image in memory at one time. |
| </p> |
| <p>Magick++ provides integrated support for the <a href="http://www.sgi.com/tech/stl/">Standard |
| Template Library</a> (STL) so that the powerful containers available |
| (e.g. <a href="http://www.sgi.com/tech/stl/Deque.html">deque</a>, |
| <a href="http://www.sgi.com/tech/stl/Vector.html">vector</a>, <a href="http://www.sgi.com/tech/stl/List.html">list</a>, |
| and <a href="http://www.sgi.com/tech/stl/Map.html">map</a>) can |
| be used to write programs similar to those possible with PERL & |
| PerlMagick. STL-compatible template versions of ImageMagick's |
| list-style operations are provided so that operations may be |
| performed on multiple images stored in STL containers. |
| </p> |
| </div> |
| <h2>Documentation</h2> |
| <div class="doc-section"> |
| <a id="documentation"></a> |
| <p>Detailed <a href="../www/Magick++/Documentation.html">documentation</a> is |
| provided for all Magick++ classes, class methods, and template |
| functions which comprise the API. See a <a href="http://www.imagemagick.org/Magick++/tutorial/Magick++_tutorial.pdf"> Gentle Introduction to Magick++</a> for an introductory tutorial to Magick++. We include the <a href="http://www.imagemagick.org/Magick++/tutorial/Magick++_tutorial.odt" >source</a> if you want to correct, enhance, or expand the tutorial.</p> |
| </div> |
| <h2>Obtaining Magick++</h2> |
| <a id="get"></a> |
| <div class="doc-section"> |
| <p>Magick++ is included as part of <a href="../index.html">ImageMagick</a> |
| source releases and may be retrieved via <a href="download.html">ftp</a> |
| or <a href="subversion.html">Subversion</a>. |
| </p> |
| </div> |
| <h2>Installation</h2> |
| <div class="doc-section"> |
| <a id="install"></a> |
| <p>Once you have the Magick++ sources available, follow these detailed |
| <a href="../www/Magick++/Install.html">installation instructions</a> for UNIX and |
| Windows. |
| </p> |
| </div> |
| <h2>Usage</h2> |
| <div class="doc-section"> |
| <p>A helper script named <kbd>Magick++-config</kbd> is installed |
| under Unix which assists with recalling compilation options required |
| to compile and link programs which use Magick++. For example, the |
| following command will compile and link the source file <kbd>demo.cpp</kbd> |
| to produce the executable <kbd>demo</kbd> (notice that quotes are |
| backward quotes): |
| </p> |
| <pre class="text"> |
| c++ `Magick++-config --cxxflags --cppflags` -O2 -o demo demo.cpp \ |
| `Magick++-config --ldflags --libs` |
| </pre> |
| <p>Windows users may get started by manually editing a project file |
| for one of the Magick++ demo programs. |
| </p> |
| <p>Note, under Windows (and possibly the Mac) it may be necessary to initialize the ImageMagick library prior to using the Magick++ library. This initialization is performed by passing the path to the ImageMagick DLLs (assumed to be in the same directory as your program) to the InitializeMagick() function call. This is commonly performed by providing the path to your program (argv[0]) as shown in the following example: </p> |
| <pre class="text"> |
| int main( int argc, char ** argv) { |
| InitializeMagick(*argv); |
| ... |
| </pre> |
| <p>This initialization step is not required under Unix, Linux, |
| Cygwin, or any other operating environment that supports the notion |
| of <em>installing</em> ImageMagick in a known location. |
| </p> |
| </div> |
| <h2>Reporting Bugs</h2> |
| <div class="doc-section"> |
| <a id="bugs"></a> |
| <p>Questions regarding usage should be directed to or to report any bugs go to |
| <a href="http://www.imagemagick.org/discourse-server/viewforum.html?f=23">Magick++ bug tracking forum</a>. |
