At least Xara Xtreme 4 has a size limitation on what it can export at 300 ppi. I often export 24 x 36 full color to 300 ppi TIF or JPG. However, Xara won't let me export much larger than that. I don't think Xara is the best application for full color vector/photo as it applies to large format applications like vehicle wraps. I create maps in Xara for large format printing. While I'd like to do 300 ppi 36 x 48 or larger, Xara won't let me. If XPD 7 is an exception - forget what I'm saying. But Xara always had a maximize size/resolution - I know, I've tried.
