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.
