I often use the "Autotrace" feature in Xara, which like Serif will create ugly pixelized edging sometimes. If a portion of the outline is extremely "pixelated", I view all the points created in the polyline shape and search for ones that need deleted or moved to an improved shape. Sometimes I use a combination of hand-drawn shapes within the vector application as well as relying on "Autotrace".

Just a suggestion.

Nice maps Ravs!
