NAME
mlib_ImageColorXYZ2RGB_Fp - XYZ to RGB color conversion SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageColorXYZ2RGB_Fp(mlib_image *dst, const mlib_image *src); DESCRIPTION
The mlib_ImageColorXYZ2RGB_Fp() function performs a color space conversion from CIE XYZ to ITU-R Rec.708 RGB with D64 white point. The source and destination images must be three-channel images. It uses the following equation: |R| |cmat[0] cmat[1] cmat[2]| |X| |G| = |cmat[3] cmat[4] cmat[5]| * |Y| |B| |cmat[6] cmat[7] cmat[8]| |Z| where cmat[] = { 3.240479, -1.537150, -0.498535, -0.969256, 1.875992, 0.041566, 0.055648, -0.204043, 1.057311 }; src[x][y] = { X, Y, Z }; dst[x][y] = { R, G, B }; PARAMETERS
The function takes the following arguments: dst Pointer to destination image. src Pointer to source image. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES
