Hi Thanks for that. Yes scaling all the numbers in the th2 file worked. Wrote a python script to go through the lines and divide each number found by a scale and rewriting the lines again into a new th2 file. That now matches over top of my scaled image.

Hi all Martin asked if I could put the script up to the wiki. Still have not got access to that so it's attached here. Why this script was needed: I had a Therion survey where the sketches had been scanned at 600 dpi and the scraps had been drawn from these images. When I scale the images to less pixels the images no longer line up under the scraps in the map editor. I needed to have lower size images but still have the th2 scraps aligning with the underlying images. The images with al the Therion data are going into a version control system hence I want to reduce the file size. Python script attached. On 09/08/2014 11:40 PM, Michael Lake wrote:

Try to divide all numbers in th2 file by 2.
