Map expansion (Normandy44)

Question: I want to expand a main map. Is there any way to get Normandy44 map without hexes?
How about loading a new map in Vassal module (import new map)? Are there any map size or resolution limitations?

You could seek out the map artist (Mark Simonitch) and see if he would export a version without the hexes, though he’d be entirely within his rights to decline, as it’s his original work. Trying to do any touchup to the raster image would take an impracticably long time even if you are very skilled, I’d guess.

Basically your available continguous block of system RAM. Map pixel dimensions are the biggest factor in how much RAM will be required. A good rule of thumb is to figure width * height * 4 as the number of bytes you’d need for a large map image.
