The pieces are sharp when I generate them. It is just that they are tiny, and it would probably take 500 of them to make a even a small coastline, and when you do it that way they start to lose their organic look because there are so many patch-worked together, and I might as well have drawn it anyway.

Thanks lostatsea, http://www.cartographersguild.com/ho...al-shapes.html is very helpful.

Seems like I'll just use them as a shape and redraw their edges. Accurately converting them to vectors and resizing rasters well takes too long...
