I just hacked my path measurement plug-in to handle this. You need
gimp-python. Once it's installed:
1. Draw a path with the pen tool over what needs to be measured.
2. Filters->Measure->Active Path
- Enter pixels (integer) from the ratio in the first box, and
units (integer) in the second box (eg, meters).
Then look in the Error console for output. Did not test it much - let
me know if it works out...
HTH,
