DESCRIPTION

17       The  mlib_ImageChannelCopy()  function  copies the selected channels of
18       the source image into the corresponding  channels  of  the  destination
19       image.  The  data  type  of  the  image  can  be MLIB_BYTE, MLIB_SHORT,
20       MLIB_USHORT, MLIB_INT, MLIB_FLOAT, or MLIB_DOUBLE.
21

PARAMETERS

23       The function takes the following arguments:
24

31       cmask    Source or destination channel selection mask. Each bit of  the
32                mask represents a channel in the image data. The least signif‐
33                icant bit (LSB) of the mask corresponds to the last channel in
34                the  image  data.  A  bit with a value of 1 indicates that the
35                channel is selected.
