interleaved
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
void mlib_VideoColorRGBXint_to_ABGRint(mlib_u32 *ABGR,
const mlib_u32 *RGBX, 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 RGBX stream and the alpha values are combined into an
interleaved A, B, G, R output stream. Within each 32-bit input pixel,
the component ordering is R (bits 31-24), G (bits 23-16), and B (bits
15-8). Within each 32-bit output pixel, the component bordering 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: if
A_array is not NULL, the values are taken from the corresponding loca‐
tions in the alpha array, otherwise a constant alpha value, specified
by A_const, is store in each output pixel. Each element in the alpha
array is an unsigned byte. w and h define the dimensions of the region
of the buffers to be processed. The linebyte parameters are used to
advance the data pointers for each of the buffers.
PARAMETERS
The function takes the following arguments:
ABGR Pointer to output buffer (word-aligned).
RGBX Pointer to input buffer (word-aligned).
A_array Pointer to array of alpha values (byte-aligned).
A_const Constant alpha value (range = 0..255).
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.
