The mlib_ImageChannelCopy() function copies the selected channels of the source image into the corresponding channels of the destination image. The data type of the image can be MLIB_BYTE, MLIB_SHORT, MLIB_USHORT, MLIB_INT, MLIB_FLOAT, or MLIB_DOUBLE.
The function takes the following arguments:
Pointer to a destination image.
Pointer to a source image.
Source or destination channel selection mask. Each bit of the mask represents a channel in the image data. The least significant bit (LSB) of the mask corresponds to the last channel in the image data. A bit with a value of 1 indicates that the channel is selected.
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
