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.
