dstOrder[3]   Specifies destination buffer channel order. For example, dstOrder[1] = 0 indicates that source channel 0 is destination channel 1.
dstStep   Destination buffer step size (width of the buffer in bytes).
pDst   Pointer to a location in a destination buffer.
pSrc   Pointer to a location in a source buffer.
pSrcDst   Pointer to a location in a buffer that contains both the source and destination.
roiSize   Specifies the height and width of an ROI.
srcDstStep   Source and destination buffer step size in bytes (width of both buffers in bytes).
srcStep   Source buffer step size (width of the buffer in bytes).


These functions step through an ROI in a source buffer, swap the source buffer channels as specified by the destination order, and write the channel data to the destination buffer.

For example, dstOrder[1] = 0 places channel 0 in the source buffer into channel 1 of the destination buffer.
