Great utility and very helpful for doing maps.
I'd like to suggest an enhancement that you might want to consider...
I do maps pixel by pixel... I generally resize maps to a size... say 1000x800 pixels, for example, and set the grid so every 10 square pixels equals one civ map square. I use your utility to make maps, and it does that very well, only I'm running into a little difficulty due to the fact that the civ coordinates run bottom to top, while the pixel coordinates in paint programs run top to bottom. Therefore, in order to create maps that are right-side up, I've got to flip my map upside down so that the pixel coordinates read the same as civ map coordinates... this is cumbersome to say the least, and makes matching the finished map to the original template difficult.
I don't know if other people make maps this way. Anyway, if there were an option to display coordinates top to bottom it would make my life, and possibly other's easier, and certainly simplify mapping.
Thanks again for the great utility.
