Description copied from interface: IntToBytePixelConverter

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 * srcscanints  + x * srcintsperpixel  + srcoff;
     int dstpos = y * dstscanbytes + x * dstbytesperpixel + dstoff;
     for each j : 0 <= j < srcintsperpixel {
         load data from srcarr[srcpos + j];
     }
     convert data to destination pixel format
     for each k : 0 <= k < dstbytesperpixel {
         store data into dstarr[dstpos + k] = pixel data;
     }
