I've completed an A5 portrait book which includes lots of images. Now I want to make a Coffee Table version of it. Effectively, twice the physical size.

I've read there are some DTP programs, and some 3rd party plugins and standalones, that, using 'AI' and other 'methods', are able to upscale images, especially Jpegs, keeping them sharp and, most importantly, artefact-free - no jagged edges, etc.

Can Xara do that? If not, it would certainly be a feature to suggest?
