Hi there. I downloaded your generator, and I immediately fell in love. It did icosahedral projections, which makes easy hex grids, and you could zoom for extra precision! it seemed like a dream come true. However, when I zoomed on the top left triangle using -l and -L, the land was warped - coming in at a different angle, which would ruin my hex grids. Mildly disappointed, I decided to go with a really big image instead, but now I've ended up with a 2.4 GB bitmap that even my loyal python modules refuse to open.

So my question: is there a way to zoom in on the icosahedral map without distorting the initial outlook?

There is an error in the icosahedral projection that makes the map not quite line up at the trisngle edges. I have tried to locate the problem, but I have not been able to get a perfect alignment. I may look at it again later.
