I've been using this for a while as a backdrop for graphical programs, so I thought I'd share the code; it's very simple really.

Condensed to one line:


Decompressed still only 19 lines:

To run in DBC just change the && to &.

Neat, but there are faster ways of drawing it.

In use I am copying it into a vertical strip then copying that across the screen, but that was over 20 lines. What is your idea?

Use box instead of dot. Lock the pixels while drawing. Or access the buffer directly: snippet

What! I had no idea you could do that! Thank you.

[edit]


Changing x and y to dwords removes half the bounds checking. I also tidied it up a bit and removed some assignments. Not sure how much "bitmap height()" and "bitmap width()" would slow it down but I don't like the idea of using globals is what is a very generic function.

[sidenote]
Any idea why when I post code on here the tabs are ridiculously huge?
