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.
