<!-- This text is in reStucturedText format, so it may look a bit odd. -->
<!-- See http://docutils.sourceforge.net/rst.html for details. -->
<p>The future and success of GraphicsMagick depends on your contributions.
By contributing to GraphicsMagick you will benefit from the
features/fixes you contribute, can take pride in taking part in the
development of a quality product, and you can tell your friends that you
contribute to the GraphicsMagick project.</p>
<p>There are a number of ways you can contribute:</p>
<ul class="simple">
<li>Submit bug reports to the GraphicsMagick bug tracking system at
SourceForge.</li>
<li>Submit patches to the GraphicsMagick patch submission system at
SourceForge.</li>
<li>Perform test builds on unusual systems and report the results.</li>
<li>Submit ideas and proposed designs to the graphicsmagick-core
mailing list.</li>
<li>Create a new language interface, dependent library, or application.</li>
<li>Join the GraphicsMagick Group as a full-fledged developer with CVS
commit access.</li>
</ul>
<p>Regardless of how you choose to contribute, your contributions will be
treated with the respect and value that they deserve.</p>
<p>Becoming a member of the GraphicsMagick Group requires a majority vote
from existing members. Your chances of being admitted to the group are
increased significantly if you have a proven track-record of success on
other open source projects, are a recognized expert in the field, or have
already demonstrated your capabilities and commitment by contributing to
the project in other ways. Please contact Bob Friesenhahn
<<a class="reference" href="mailto:bfriesen@simple.dallas.tx.us">bfriesen@simple.dallas.tx.us</a>> in order to be considered for group
membership.</p>
<div class="section">
<h1><a id="areas-to-contribute" name="areas-to-contribute">Areas To Contribute</a></h1>
<p>The following are areas where significant contributions may be made to
the GraphicsMagick project:</p>
<ul class="simple">
<li>Support building and distributing GraphicsMagick RPMs for Linux.</li>
<li>Support a FreeBSD "port" in the FreeBSD ports collection for
GraphicsMagick.</li>
<li>Set up an FTP mirror site for GraphicsMagick.</li>
<li>Create a language interface using SWIG <<a class="reference" href="http://www.swig.org/">http://www.swig.org/</a>> to
support scripting in Perl, Python, TCL/TK, Guile, MzScheme, Ruby,
Java, PHP, and CHICKEN, based on a common implementation.</li>
<li>Create a new utility command parser based on a separate LALR or
XML-based syntax definition, and using an approach suitable to
replace the existing error-prone command parsers in magick/command.c</li>
<li>Create a vector encoder for EPS, Postscript, PDF, SVG
<<a class="reference" href="http://www.w3.org/Graphics/SVG/">http://www.w3.org/Graphics/SVG/</a>>, Macromedia Flash
(SWF), WebCGM <<a class="reference" href="http://www.w3.org/Graphics/WebCGM/">http://www.w3.org/Graphics/WebCGM/</a>>, or WMF.</li>
<li>Create an OpenEXR coder based on the OpenEXR
<<a class="reference" href="http://www.openexr.org/">http://www.openexr.org/</a>> library from Industrial Light & Magic.</li>
<li>Create a <em>pstoedit</em> module to import Postscript, EPS, and PDF
files as vector data using pstoedit <<a class="reference" href="http://www.pstoedit.net/">http://www.pstoedit.net/</a>> which
already includes a high-quality driver to render Postscript vectors via
GraphicsMagick. This module could also export vector data in many
formats using pstoedit's output drivers.</li>
<li>Create a coder to support the CALS
<<a class="reference" href="http://www.fileformat.info/format/cals/">http://www.fileformat.info/format/cals/</a>> raster file format.</li>
<li>Support reading/rendering HP printer PCL formats.</li>
<li>Add integrated Adobe XMP
<<a class="reference" href="http://www.adobe.com/products/xmp/main.html">http://www.adobe.com/products/xmp/main.html</a>> profile support for
TIFF, JPEG, PNG, PDF, EPS, and Postscript.</li>
<li>Add a GeoTIFF <<a class="reference" href="http://www.remotesensing.org/geotiff/geotiff.html">http://www.remotesensing.org/geotiff/geotiff.html</a>>
extension to GraphicsMagick.</li>
<li>Port Erik Reinhard's super-cool Parameter Estimation For
Photographic Tone Reproduction
<<a class="reference" href="http://www.cs.ucf.edu/~reinhard/Reinhard02/">http://www.cs.ucf.edu/~reinhard/Reinhard02/</a>> algorithm to
GraphicsMagick.</li>
<li>Create a replacement (using a portable Widget set such as FLTK) for the
IMDisplay Windows GUI program.</li>
<li>Write a shim-layer to allow The GIMP <<a class="reference" href="http://www.gimp.org/">http://www.gimp.org/</a>> to be
executed as a loadable process module providing GraphicsMagick
users with access to GIMP features.</li>
<li>Port your existing GIMP module to GraphicsMagick as a loadable
process module.</li>
<li>Create an interface between GraphicsMagick and OpenOffice.org.
<<a class="reference" href="http://www.openoffice.org/">http://www.openoffice.org/</a>> so that OpenOffice may load and save
any format supported by GraphicsMagick. OpenOffice.org offers a
separate SDK so there may be a number of other opportunities to
explore.</li>
<li>Resolve the remaining porting bugs in the FlashPIX library.</li>
<li>Complete the port of ralcgm to Windows so that it may be used as a
delegate under Windows.</li>
