mlib_VideoColorYUV2ABGR420_WX3 - YUV to RGB color conversion SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_VideoColorYUV2ABGR420_WX3(mlib_u8 *abgr, const mlib_u8 *y, const mlib_u8 *u, const mlib_u8 *v, mlib_s32 width, mlib_s32 height, mlib_s32 abgr_stride, mlib_s32 y_stride, mlib_s32 uv_stride, mlib_s32 left, mlib_s32 top, mlib_s32 right, mlib_s32 bottom); DESCRIPTION
The mlib_VideoColorYUV2ABGR420_WX3() function performs YUV to RGB color conversion used in MPEG1 and MPEG2 video compression in the 4:2:0 sequence. It performs color conversion together with window clipping and 3X zooming. The luminance component is stored in Y, the chrominance components are stored in U and V, respectively. The size of the chrominance image depends on the chroma format used by the sequence. In this sequence, the chrominance components are subsampled 2-to-1 in both the horizon- tal and vertical directions in respect to the luminance component. PARAMETERS
The function takes the following arguments: abgr Pointer to the destination packed ABGR image. abgr must be 8-byte aligned. y Pointer to the source Y component. y must be 8-byte aligned. u Pointer to the source U component. u must be 4-byte aligned. v Pointer to the source V component. v must be 4-byte aligned. width Width of the image. width must be a multiple of 8. height Height of the image. height must be a multiple of 2. abgr_stride Stride, in bytes, between adjacent rows in the ABGR image. abgr_stride must be a multiple of 8. y_stride Stride, in bytes, between adjacent rows in the Y component image. y_stride must be a multiple of 8. uv_stride Stride, in bytes, between adjacent rows in the U and V component images. uv_stride must be a multiple of 8. left Left border of clipping window. 0 <= left < right <= width. top Top border of clipping window. 0 <= top < bottom <= height. right Left border of clipping window. 0 <= left < right <= width. bottom Bottom border of clipping window. 0 <= top < bottom <= height. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES
