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.
