NAME
libggigcp : GGI extension for color and palette

DESCRIPTION
LibGGIGCP is a generic color and palette management extension. It supports conversion between different color spaces such as RGBA, YUV, HSV and CMYK.

ENVIRONMENT VARIABLES

GCP_DEBUG
    The debugging level for LibGGIGCP:

    0 or unset
        debug output is off; debugging is off

    255 all debug output is on

    You may also bitwise-or any of the following together:

    •   2 : debug core

    •   4 : debug mode setting

    •   8 : debug color handling

    •   16 : debug drawing

    •   32 : misc debugging output

    •   64 : debug dynamic library handling

    •   128 : debug event handling

    The debugging output can be quite verbose and in most cases you should redirect stderr so that it does not interfere with your program's output.

GCP_DEBUGSYNC
    Turn on synchronous debugging output, flushing the output buffers before returning from DPRINT calls.

GGI_CONFDIR
    Override compiled-in path to global config files (Win32 only, but not Cygwin).

Note that the last environment variable really begin with GGI, and not GCP.
