DESCRIPTION

21       The interleaved RGBX stream and the alpha values are combined  into  an
22       interleaved  A,  B, G, R output stream. Within each 32-bit input pixel,
23       the component ordering is R (bits 31-24), G (bits 23-16), and  B  (bits
24       15-8).  Within  each  32-bit output pixel, the component bordering is A
25       (bits 31-24), B (bits 23-16), G (bits 15-8),  and  R  (bits  7-0).  The
26       alpha  values  for  this  function  work  in  the following fashion: if
27       A_array is not NULL, the values are taken from the corresponding  loca‐
28       tions  in  the alpha array, otherwise a constant alpha value, specified
29       by A_const, is store in each output pixel. Each element  in  the  alpha
30       array  is an unsigned byte. w and h define the dimensions of the region
31       of the buffers to be processed. The linebyte  parameters  are  used  to
32       advance the data pointers for each of the buffers.
