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 * dstscanints  + x * dstintsperpixel  + dstoff;
    for each j : 0 <= j < srcbytesperpixel {
        load data from srcarr[srcpos + j];

    convert data to destination pixel format
    for each k : 0 <= k < dstintsperpixel {
        store data into dstarry[dstpos + k] = pixel data;

Params:
  • srcbuf – the byte array containing the source data
  • srcoff – the index in the array of the first source pixel data

  • dstoff – the index in the array of the first destination pixel data
  • dstscanints – number of array indices between rows of data in the destination
  • w – the number of pixels to process across before moving to the next row
  • h – the number of rows of pixels to process
