CMCreateTransformExtW function (icm.h)

  • Article

Creates a color transform that maps from an input LOGCOLORSPACEW to an optional target space and then to an output device, using a set of flags that define how the transform should be created.

Syntax

HCMTRANSFORM CMCreateTransformExtW(
  LPLOGCOLORSPACEW lpColorSpace,
  LPDEVCHARACTER   lpDevCharacter,
  LPDEVCHARACTER   lpTargetDevCharacter,
  DWORD            dwFlags
);

Parameters

lpColorSpace

Pointer to an input logical color space structure.

lpDevCharacter

Pointer to a memory-mapped device profile.

lpTargetDevCharacter

Pointer to a memory-mapped target profile.

dwFlags

Specifies flags to used control creation of the transform. For details, see CMM transform creation flags.

Return value

If this function succeeds, the return value is a color transform in the range 256 to 65,535. Since only the low WORD of the transform is retained, valid transforms cannot exceed this range.

If this function fails, the return value is an error code having a value less than 256. When the return value is less than 256, signaling an error, the CMM should use SetLastError to set the last error to a valid error value as defined in Winerror.h.

Remarks

Every CMM is required to export this function.
