XcmsConvertColors() XcmsConvertColors()
Name
XcmsConvertColors - convert color specifications in XcmsColor structures to another color space specific encoding.
Synopsis
Status XcmsConvertColors(ccc, colors_in_out, ncolors, target_format,
compression_flags_return)
XcmsCCC ccc;
XcmsColor colors_in_out[];
unsigned int ncolors;
XcmsColorFormat target_format;
Bool compression_flags_return[];
Arguments
ccc Specifies the color conversion context. 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.
ncolors Specifies the number of XcmsColor structures in the color specification array.
target_format
Specifies the target color specification format.
compression_flags_return
Specifies an array of ncolors Boolean values for returning compression status of each color conversion. If a non-NULL pointer
is supplied, each element in the array is set to True if the corresponding color in the color specification array was com-
pressed, and False otherwise. Pass NULL if the compression status is not useful.
Returns
Zero on failure, non-zero on success.
Availability
Release 5 and later.
Description
The XcmsConvertColors() function converts the color specifications in the specified array of XcmsColor structures from their current format
(which may vary from element to element of the array) to a single target format using the specified CCC. If all the conversions succeed
without gamut compression, XcmsConvertColors() returns XcmsSuccess. If one or more of the conversions required gamut compression, the
function returns XcmsSuccessWithCompression, and sets the appropriate flags in compression_flags_return array. If any of the conversions
fail, the function returns XcmsFailure and the contents of the color specification array are left unchanged.
Structures
The XcmsColor and XcmsColorFormat structures are shown on the XcmsColor reference page.
