mlib_VideoColorYUV444int_to_ARGBint(3MLIB)		    mediaLib Library Functions			mlib_VideoColorYUV444int_to_ARGBint(3MLIB)

NAME
mlib_VideoColorYUV444int_to_ARGBint - color convert YUV interleaved to ARGB interleaved SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> void mlib_VideoColorYUV444int_to_ARGBint(mlib_u32 *ARGB, const mlib_u8 *YUV, const mlib_u8 *A_array, mlib_u8 A_const, mlib_s32 w, mlib_s32 h, mlib_s32 dlb, mlib_s32 slb, mlib_s32 alb); DESCRIPTION
The YUV pixel stream is converted into an ARGB pixel stream. All pixel components are 8-bit unsigned integers. All buffers have dimensions w and h. The alpha values for this function work in the following fashion: o If A_array pointer is not NULL, the values are taken from there. It has to have the same dimensions as the Y buffer. o If A_array pointer is NULL, the alpha values for every pixel are set to A_const. The following equation is used: |R| |1.1644 0.0000 1.5966| [|Y| | 16.0000|] |G| = |1.1644 -0.3920 -0.8132| * [|U| - |128.0000|] |B| |1.1644 2.0184 0.0000| [|V| |128.0000|] PARAMETERS
The function takes the following arguments: ARGB Pointer to output buffer. YUV Pointer to Y input buffer. A_array Array of alpha values. A_const Constant alpha value. w Image width in pixels. h Image height in lines. dlb Linebytes for output buffer. slb Linebytes for input buffer. alb Linebytes for alpha buffer. RETURN VALUES
