NAME
mlib_VideoColorRGBseq_to_ABGRint - convert RGB sequential to ABGR interleaved
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
void mlib_VideoColorRGBseq_to_ABGRint(mlib_u32 *ABGR, const mlib_u8 *R,
const mlib_u8 *G, const mlib_u8 *B,
const mlib_u8 *A_array, mlib_u8 A_const,
mlib_s32 w, mlib_s32 h,
mlib_s32 dlb, mlib_s32 slb);
DESCRIPTION
The R, G, and B streams, and the A values are combined into an A, B, G, R interleaved byte stream. 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.
R
-
Pointer to input R buffer.
G
-
Pointer to input G buffer.
B
-
Pointer to input B 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 buffers.
RETURN VALUES
None.
