There're 2 overloading cutBitmap() methods that are also useful when subsetting a Bitmap
sheet.
//Subsets the source bitmap to frames with the specified size w x h,
//stores the result in a bitmap array.
//Parameters:
// source - the specified bitmap to be subset
// result - a bitmap array that stores the frames
// imgid - the image id of source
// rows - the number of rows
// cols - the number of cols
// w - the width of the frame
// h - the height of the frame
public static void cutBitmap(Bitmap source,Bitmap [] result, int imgid,
int rows, int cols, int w, int h){
for ( int i=0;i<rows;i++){
for ( int j=0;j<cols;j++){
result[imgid+i*cols+j]
= Bitmap. createBitmap (source, j*w, i*h, w, h);

}
