DESCRIPTION

17       The  mlib_ImageBlendRGBA2BGRA() function blends the source image of the
18       RGBA format into the destination image of the BGRA format.
19
20
21       The image type must be MLIB_BYTE. The  source  and  destination  images
22       must contain four channels.
23
24
25       It uses the following equation:
26
27         Cd = Cs*As + Cd*(1 - As)
28         Ad = Ad
29
30
31
32       where,  Cs and Cd are the RGB color components of the source and desti‐
33       nation images, respectively.  As and Ad are the alpha components of the
34       source and destination images, respectively.
35
