Hi MrBrian,

Regarding Xara 6 (Designer Pro 6), check out this video by Xhris:

He talks about photos from about 1:00 onwards, and you might be interested in the part about the clone tool at 3:17 on.

Welcome Mr Brian,
Xaras content aware scale is one tool that works far better than the one in Photoshop so I use Xara and Photoshop together on some projects combining the best of both programs.
