NAME
XcmsConvertColors - convert CCC color specifications
SYNTAX
Status XcmsConvertColors(XcmsCCC ccc, XcmsColor colors_in_out[],
unsigned int ncolors, XcmsColorFormat target_format, Bool
compression_flags_return[]);
ARGUMENTS
ccc Specifies the CCC. If Conversion is between device-
independent color spaces only (for example, TekHVC to
CIELuv), the CCC is necessary only to specify the Client
White Point.
colors_in_out
Specifies an array of color specifications. Pixel members
are ignored and remain unchanged upon return.
compression_flags_return
Returns an array of Boolean values indicating compression
status. If a non-NULL pointer is supplied, each element of
the array is set to True if the corresponding color was
compressed and False otherwise. Pass NULL if the compression
status is not useful.
ncolors Specifies the number of XcmsColor structures in the color-
specification array.
target_format
Specifies the target color specification format.
DESCRIPTION
The XcmsConvertColors function converts the color specifications in the
specified array of XcmsColor structures from their current format to a
single target format, using the specified CCC. When the return value
is XcmsFailure, the contents of the color specification array are left
unchanged.
The array may contain a mixture of color specification formats (for
example, 3 CIE XYZ, 2 CIE Luv, and so on). When the array contains
both device-independent and device-dependent color specifications and
the target_format argument specifies a device-dependent format (for
example, XcmsRGBiFormat, XcmsRGBFormat), all specifications are
converted to CIE XYZ format and then to the target device-dependent
format.
