/*
* 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
