| * SYNOPSIS |
| * |
| * ARGUMENT |
| * src pointer to source image data |
| * dst pointer to destination image data |
| * slb source image line stride in bytes |
| * dlb destination image line stride in bytes |
| * dsize image data size in pixels |
| * xsize image width in pixels |
| * ysize image height in lines |
| * cmask channel mask |
| * |
| * DESCRIPTION |
| * extract the right or left 3 channels of a 4-channel image to |
| * a 3-channel image -- VIS version low level functions. |
| * |
| * ABGR => BGR (43R), or RGBA => RGB (43L) |
| * |
| * NOTE |
| * These functions are separated from mlib_v_ImageChannelExtract.c |
| * for loop unrolling and structure clarity. |
