mlib_VideoColorRGBseq_to_ABGRint(3MLIB)

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:

  • 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.

  • 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.
