to ARGB interleaved
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
void mlib_VideoColorUYVY422int_to_ARGBint(mlib_u32 *ARGB,
const mlib_u32 *UYVY, 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 UYVY pixel stream is converted into an ARGB pixel stream. All pixel
components are 8-bit unsigned integers. The UYVY buffer has dimensions
w/2 and h. The ARGB buffer has dimensions w and h. Dimension w is
assumed to be even.
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.
UYVY Pointer to 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
None.
