mlib_VideoColorARGB2JFIFYCC420 - ARGB to JFIF YCbCr color conversion
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_VideoColorARGB2JFIFYCC420(mlib_u8 *y0, mlib_u8 *y1, mlib_u8 *cb, mlib_u8 *cr, const mlib_u8 *argb0, const mlib_u8 *argb1, mlib_s32 n);
The mlib_VideoColorARGB2JFIFYCC420() function performs color space conversion from ARGB to YCbCr to together with sampling rate conversion when used in the JPEG File Interchange Format (JFIF).
The function takes the following arguments: y0 Pointer to upper destination Y component row. y0 must be 8-byte aligned. y1 Pointer to lower destination Y component row. y1 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. argb0 Pointer to upper source ARGB multi-component row. argb0 must be 8-byte aligned. argb1 Pointer to lower source ARGB multi-component row. argb1 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.
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
