cristy149d58c2013-08-07 19:44:54 +0000181<p><a href="../api/Magick++/index.html">Magick++ API</a> is the object-oriented C++ API to the <a href="../index.html">ImageMagick</a> image-processing library.</p>
182<p>Magick++ supports an object model which is inspired by <a href="perl-magick.html">PerlMagick</a>.
cristydcca3fa2010-12-29 21:50:07 +0000183Images support implicit reference counting so that copy constructors
184and assignment incur almost no cost. The cost of actually copying an
185image (if necessary) is done just before modification and this copy
186is managed automagically by Magick++. De-referenced copies are
187automagically deleted. The image objects support value (rather than
188pointer) semantics so it is trivial to support multiple generations
189of an image in memory at one time.
190</p>
cristy2bd2a982011-02-15 00:52:58 +0000191<p>Magick++ provides integrated support for the <a href="http://www.sgi.com/tech/stl/">Standard
192Template Library</a> (STL) so that the powerful containers available
193(e.g. <a href="http://www.sgi.com/tech/stl/Deque.html">deque</a>,
194<a href="http://www.sgi.com/tech/stl/Vector.html">vector</a>, <a href="http://www.sgi.com/tech/stl/List.html">list</a>,
cristyac1b4322013-07-28 13:58:06 +0000195and <a href="http://www.sgi.com/tech/stl/Map.html">map</a>) can
cristydcca3fa2010-12-29 21:50:07 +0000196be used to write programs similar to those possible with PERL &amp;
197PerlMagick. STL-compatible template versions of ImageMagick's
198list-style operations are provided so that operations may be
199performed on multiple images stored in STL containers.

cristy8ee7f242013-06-20 16:08:44 +0000227<p>A helper script named <code>Magick++-config</code> is installed
cristydcca3fa2010-12-29 21:50:07 +0000228under Unix which assists with recalling compilation options required
229to compile and link programs which use Magick++. For example, the
cristy8ee7f242013-06-20 16:08:44 +0000230following command will compile and link the source file <code>demo.cpp</code>
231to produce the executable <code>demo</code> (notice that quotes are
cristydcca3fa2010-12-29 21:50:07 +0000232backward quotes):
233</p>
234<pre class="text">
235c++ `Magick++-config --cxxflags --cppflags` -O2 -o demo demo.cpp \
236 `Magick++-config --ldflags --libs`
237</pre>
238<p>Windows users may get started by manually editing a project file
239for one of the Magick++ demo programs.
240</p>
241<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>
242<pre class="text">
243int main( int argc, char ** argv) {
244 InitializeMagick(*argv);
245 ...
246</pre>
247<p>This initialization step is not required under Unix, Linux,
248Cygwin, or any other operating environment that supports the notion
249of <em>installing</em> ImageMagick in a known location.
