For a simple blocking like this, you're better off using a gani and just setshape(1,width,height) instead, much like GK uses.

What you do is you load the image in a gani, and where you want the top-left of the blocking to start, you place at the corner of the green box in graalshop. Open up a tree gani from GK and you'll see what I mean. Then in Graal just setcharani();setshape() and it will adopt the blocking correctly.

If you need help, just post the image and I'll make it up for you really quick.
