mlib_VideoColorJFIFYCC2ABGR444 - JFIF YCbCr to ABGR color conversion SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_VideoColorJFIFYCC2ABGR444(mlib_u8 *abgr, const mlib_u8 *y, const mlib_u8 *cb, const mlib_u8 *cr, mlib_s32 n); DESCRIPTION
The mlib_VideoColorJFIFYCC2ABGR444() function performs color space conversion from YCbCr to ABGR when used in the JPEG File Interchange Format (JFIF). The following equation is used: A = 0xFF R = Y + 1.40200 * (Cr - 128) G = Y - 0.34414 * (Cb - 128) - 0.71414 * (Cr - 128) B = Y + 1.77200 * (Cb - 128) PARAMETERS
The function takes the following arguments: abgr Pointer to destination ABGR multi-component row. abgr must be 8-byte aligned. y Pointer to source Y component row. y must be 8-byte aligned. cb Pointer to source Cb component row. cb must be 8-byte aligned. cr Pointer to source Cr component row. cr must be 8-byte aligned. n Length of Y component row. The length of Cb and Cr component rows must be n. The length of the ABGR multi-component row must be 4*n. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES
