I've bought a module to add to my campaign, but the maps are large, and at 35 pixel per unit resolution. For various reasons I need them at the default 70 pixel per unit res. So I copy the map to a new page, and change the resolution, but this makes it unwieldy and very slow to load, and it won't load on some player's lower spec machines. The answer is to crop it. This is sort of achievable just by making the page smaller, and dragging the map so that only the right part of it shows (actually doing this on several pages, each with a different part of the map). However, it still seems to take an age to load - I assume because it is still loading the full-size graphic in the background. The map is a bought asset from the Marketplace, and I can't see any way to cut and paste it into an external editor to cut it up into smaller chunks/crop it (for understandable commercial reasons, protecting copyright & revenue streams...). So, is there any way of cropping the map in Roll20?
