Forgive me for being dim but I can't seem to make this river thing work any way I try.

I take it map c and h need to be the same size and then you draw the lines onto c using h as a guide, or are you supposed to draw on each?

Gimp simply won't let me alter any of the images to the values necessary, it allows one dimension but puts its own in for the second, so you can't get both maps the same size!

How do you save just the one layer?
