# Contributing to GraphicsMagick

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.

There are a number of ways you can contribute:

- Submit bug reports to the GraphicsMagick bug tracking system at SourceForge.
- Submit patches to the GraphicsMagick patch submission system at SourceForge.
- Perform test builds on unusual systems and report the results.
- Submit ideas and proposed designs to the graphicsmagick-core mailing list.
- Create a new language interface, dependent library, or application.
- Join the GraphicsMagick Group as a full-fledged developer with CVS commit access.

Regardless of how you choose to contribute, your contributions will be treated with the respect and value that they deserve.

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 <bfriesen@simple.dallas.tx.us> in order to be considered for group membership.

# Areas To Contribute

The following are areas where significant contributions may be made to the GraphicsMagick project:

- Support building and distributing GraphicsMagick RPMs for Linux.
- Act as formal maintainer for the Gentoo Linux GraphicsMagick ebuild so that it is added back to Portage. This is not difficult since the ebuild has been actively maintained via the Gentoo bug tracking system. At the very least, registering a vote for the Gentoo bug may be helpful. See http://bugs.gentoo.org/show_bug.cgi?id=190372.
- Set up an FTP mirror site for GraphicsMagick.
- Create a language interface using SWIG <http://www.swig.org/> to support scripting in Perl, Python, TCL/TK, Guile, MzScheme, Ruby, Java, PHP, and CHICKEN, based on a common implementation.
- 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
- Create a vector encoder for EPS, Postscript, PDF, SVG <http://www.w3.org/Graphics/SVG/>, Macromedia Flash (SWF), WebCGM <http://www.w3.org/Graphics/WebCGM/>, or WMF.
- Create an OpenEXR coder based on the OpenEXR <http://www.openexr.com/> library from Industrial Light & Magic.
- Create a pstoedit module to import Postscript, EPS, and PDF files as vector data using pstoedit <http://www.pstoedit.net/> 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.
- Work on adding EXIF profile writing support which works for JPEG and TIFF formats.
- Add integrated Adobe XMP <http://www.adobe.com/products/xmp/index.html> profile support for TIFF, JPEG, PNG, PDF, EPS, and Postscript.
- Port Erik Reinhard's super-cool Parameter Estimation For Photographic Tone Reproduction <http://www.cs.ucf.edu/~reinhard/Reinhard02/> algorithm to GraphicsMagick.
- Create a replacement (using a portable Widget set such as FLTK) for the IMDisplay Windows GUI program and possibly the X11 'display' program.
- Create an interface between GraphicsMagick and OpenOffice.org. <http://www.openoffice.org/> 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.
- Complete the port of ralcgm to Windows so that it may be used as a delegate under Windows.
