Description copied from interface: ByteToBytePixelConverter

Copies a rectangular region of data from the source array to the destination array using the following relationship:

 for each xy : 0 <= x,y < w,h {
     int srcpos = y * srcscanbytes + x * srcbytesperpixel + srcoff;
     int dstpos = y * dstscanbytes + x * dstbytesperpixel + dstoff;
     for each j : 0 <= j < srcbytesperpixel {
         load data from srcarr[srcpos + j];
     }
     convert data to destination pixel format
