| /* |
| * FUNCTIONS |
| * mlib_ImageChannelExtract - Copy the selected channels of the source |
| * image into the destination image |
| * |
| * SYNOPSIS |
| * mlib_status mlib_ImageChannelExtract(mlib_image *dst, |
| * mlib_image *src, |
| * mlib_s32 cmask); |
| * ARGUMENT |
| * dst Pointer to destination image. |
| * src Pointer to source image. |
| * cmask Source channel selection mask. |
| * The least significant bit (LSB) is corresponding to the |
| * last channel in the source image data. |
| * The bits with value 1 stand for the channels selected. |
| * If more than N channels are selected, the leftmost N |
| * channels are extracted, where N is the number of channels |
| * in the destination image. |
| * |
| * RESTRICTION |
| * The src and dst must have the same width, height and data type. |
| * The src and dst can have 1, 2, 3 or 4 channels. |
| * The src and dst can be either MLIB_BYTE, MLIB_SHORT, MLIB_INT, |
| * MLIB_FLOAT or MLIB_DOUBLE. |
| * |
| * DESCRIPTION |
| * Copy the selected channels of the source image into the |
| * destination image |
