interleaved
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
void mlib_VideoColorRGBint_to_ABGRint(mlib_u32 *ABGR,
const mlib_u8 *RGB, 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 interleaved RGB stream, and the A values are combined into an A, B,
G, R interleaved byte stream. Within each 24-bit input pixel, the com‐
ponent ordering is R (bits 23-16), G (bits 15-8), and B (bits 7-0).
Within each 32-bit output word, the component ordering is A (bits
31-24), B (bits 23-16), G (bits 15-8), and R (bits 7-0).
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 R, G, and B
buffers.
o If A_array pointer is NULL, the alpha values for every pixel
are set to A_const.
PARAMETERS
The function takes the following arguments:
ABGR Pointer to output buffer.
RGB 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.
