Hi Michael,
I tried your code at first. But it did't work as well.
Although
MinX = 0, MinY = 0, MaxX = 13184, MaxY = 9933.
Iterator is stoped at x = 13184, y = 3
while trying to perform iter.setSample(c);
with following error:
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 52736
at java.awt.image.DataBufferDouble.setElemFloat(Unknown Source)

The Tile is 4 pixels high. That is why I thought using tiles will help.
