53 This group of functions supports digital image composition. They are
54 low-level, in-place, blending functions.
55 The image type must be MLIB_BYTE. The input and output images must con‐
58 tain three or four channels. For three-channel images, the alpha value
59 is as if the alpha value is 1.
60 BSRC1 is one of the following: ZERO, ONE, SC, OMSC, DA, SA, OMDA, or
63 OMSA. BSRC2 is one of the following: ZERO, ONE, DC, OMDC, DA, SA, OMDA,
64 OMSA, or SAS.
65 The following are predefined blend factor types used in mediaLib image
68 composition functions.

105 [*]: The components of the first source image pixel are (Rd,Gd,Bd,Ad),
109 and the components of the second source pixel are (Rs,Gs,Bs,As). Func‐
110 tion f = min(As,1-Ad). The first source image is also the destination
111 image.
112 The blending formula for in-place processing is:
115 Cd = Cd*D + Cs*S
117 where Cd is the destination pixel (Rd,Gd,Bd,Ad), Cs is the source pixel
121 (Rs,Gs,Bs,As), and D and S are the blend factors for the destination
122 and source, respectively.
123
125 Each of the functions takes the following arguments:
126 src1dst Pointer to the first source and the destination image.
128 src2 Pointer to the second source image.
131 cmask Channel mask to indicate the alpha channel. Each bit of the
134 mask represents a channel in the image. The channel corre‐
135 sponding to the 1 bit is the alpha channel. cmask must be
136 either 0x01 or 0x08.
137
140 Each of the functions returns MLIB_SUCCESS if successful. Otherwise it
141 returns MLIB_FAILURE.
