XcmsColor() XcmsColor()
Name
XcmsColor – Xcms color structure.
Availability
Release 5 and later.
Description
The XcmsColor structure contains a union of substructures, each sup‐
porting a color space specific encoding.
The XcmsColorFormat type is used to identify the color space associated
with the values in the XcmsColor structure. It is also used as an
argument to some Xcms functions to indicate the desired format of
returned color specifications.
Structures
The XcmsColor structure contains:
typedef unsigned long XcmsColorFormat; /* Color Specification Format */
