mlib_VideoColorRGB2JFIFYCC422 - RGB to JFIF YCbCr color conversion SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_VideoColorRGB2JFIFYCC422(mlib_u8 *y, mlib_u8 *cb, mlib_u8 *cr, const mlib_u8 *rgb, mlib_s32 n); DESCRIPTION
The mlib_VideoColorRGB2JFIFYCC422() function performs color space conversion from RGB to YCbCr together with sampling rate conversion when used in the JPEG File Interchange Format (JFIF). PARAMETERS
The function takes the following arguments: y Pointer to destination Y component row. y must be 8-byte aligned. cb Pointer to destination Cb component row. cb must be 8-byte aligned. cr Pointer to destination Cr component row. cr must be 8-byte aligned. rgb Pointer to source RGB multi-component row. rgb must be 8-byte aligned. n Length of Y component row. n must be even. The length of Cb and Cr component rows must be n/2. The length of the RGB multi-component row must be 3*n. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES
