DESCRIPTION
Given a pair of images in Lab format, these functions calculate CIE76, CMC(1:1) and CIEDE2000 colour difference images. These are the basic colour difference calculators in VIPS --- other colour difference functions, such as im_dE_fromXYZ(3), are provided as a convenience to the programmer.See im_Lab2XYZ(3) for an explanation of the various colour spaces VIPS supports and how to convert between them.
RETURN VALUE
The functions return 0 on success and -1 on error.SEE ALSO
im_col_XYZ2rgb(3), im_XYZ2rgb(3), im_dE_fromXYZ(3).COPYRIGHT
