<DIV>A method I used to copy from a previous survey was to export the centreline
as a xvi file. Then take a jpg of the old survey and scale it so the pixel count
matches that of the xvi file. </DIV>
<DIV>The next step was to use both images as background images in the th2 file.
A bit of adjustment of the position location to make them match then it was
simple to copy the old survey. </DIV>
<DIV> </DIV>
<DIV>Now I cant align the images as the zoom function now changes the scales of
the two images differently. If I use a jpg to trace over and zoom in to trace a
detailed area the scaling goes off. The resultant lines are to the wrong scale
and/or are misplaced.</DIV>
<DIV> </DIV>
<DIV>Is there a way of fixing the scale of a background image so it scales
properly. It seems to go wrong with the + – and scroll wheel.</DIV>
