Yikes - I thought so....
I tried Roberto's suggestion and set up a huge virtual screen - but all of the icons, text, etc were still small - just on a larger area.
If you could make the gui/text bigger, the virtual screen ought to give you a higher resolution.
How close to the raster does the trace need to be - do all of the numbers need to come out?
