XcmsConvertColors(3X11) XcmsConvertColors(3X11) NAME
XcmsConvertColors - convert CCC color specifications 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
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. Specifies an array of color specifications. Pixel members are ignored and remain unchanged upon 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. Specifies the num- ber of XcmsColor structures in the color-specification array. 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 exam- ple, XcmsRGBiFormat, XcmsRGBFormat), all specifications are converted to CIE XYZ format and then to the target device-dependent format.

XcmsWhiteAdjustProc() XcmsWhiteAdjustProc() Name XcmsWhiteAdjustProc - interface definition for the white point adjustment procedure. Synopsis typedef Status (*XcmsWhiteAdjustProc)(ccc, initial_white_point, target_white_point, target_format, colors_in_out, ncolors, compression_flags_return) XcmsCCC ccc; XcmsColor *initial_white_point; XcmsColor *target_white_point; XcmsColorFormat target_format; XcmsColor colors_in_out[]; unsigned int ncolors; Bool compression_flags_return[]; Arguments ccc Specifies the color conversion context. initial_white_point Specifies the initial white point. target_white_point Specifies the target white point. target_format Specifies the target color specification format. 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. compression_flags_return Specifies an array of Boolean values (or NULL) for returned information that indicates if the color was compressed. For example, if this routine returns XcmsSuccessWithCompression and compression_flags_ return[3] is True, this indicates that the fourth color specified in the color specification array was compressed. If the call- ing routine is not interested in knowing which color was compressed when the return value is XcmsSuccessWithCompression, it is allowed to pass a NULL for this argument. Returns Zero on failure, non-zero on success. Availability Release 5 and later. Description XcmsWhiteAdjustProc is a function that takes the color specifications, whose associated white point is initial_white_point, and modifies them for the target_white_point; returning the color specifications in the format specified by target_format.
