|
|
.SH ARGUMENTS
|
|
.IP \fIccc\fP 1i
|
|
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.
|
|
.IP \fIcolors_in_out\fP 1i
|
|
Specifies an array of color specifications.
|
|
Pixel members are ignored and remain unchanged upon return.
|
|
.IP \fIcompression_flags_return\fP 1i
|
|
Specifies an array of Boolean values for returning compression status.
|
|
If a non-NULL pointer is supplied,
|
|
each element of the array is set to
|
|
.ZN True
|
|
if the corresponding color was compressed, and
|
|
.ZN False
|
|
otherwise.
|
|
Pass NULL if the compression status is not useful.
|
|
.IP \fIncolors\fP 1i
|
|
Specifies the number of
|
|
.ZN XcmsColor
|
|
structures in the color specification array.
|
|
.IP \fItarget_format\fP 1i
|
|
Specifies the target color specification format.
|
|
.SH DESCRIPTION
|
|
The
|
|
.ZN XcmsConvertColors
|
|
function converts the color specifications in the specified array of
|
|
.ZN XcmsColor
|
|
structures from their current format to a single target format,
|
|
using the specified CCC.
|
|
When the return value is
|
|
.ZN XcmsFailure ,
|
|
the contents of the color specification array are left unchanged.
|
|
.LP
|
|
The array may contain a mixture of color specification formats
|
|
(for example, 3 CIE XYZ, 2 CIE Luv, ...).
|
|
Note that when the array contains both device-independent and
|
|
device-dependent color specifications, and the target_format argument specifies
|
|
a device-dependent format (for example,
|
|
.ZN XcmsRGBiFormat ,
|
|
.ZN XcmsRGBFormat )
|
|
all specifications are converted to CIE XYZ format then to the target
|
|
device-dependent format.
