Hello fellow web designers. I've just started using Xara LX as a design tool for web site interfaces and there's one aspect I am stuck on.

Aliasing and smoothing are mucking up my 1px borders and lines and so forth. Is there a way to keep lines crisp and sharp (not smoothed or anti-aliased) while exporting to PNG?

Any other tips for web designers using Xara LX?

My background has been about 6 years using Illustrator for my interfaces. Photoshop was used before that. Ubuntu LTS 6.06. Also have some Inkscape experience.
