Thanks for the tip!

I tried downloading it, unpacked to the plugin/analyze folder, but when compiling it always gives me a "plugin or class not found". I've had a bit of a look around the file, but can't see what it's complaining about. Does it require another plugin/macro? there seems to be one called "GHT_", but I can't see any reference to it in the code.

Cheers again!

Try using a linear Hough Transform to detect the lines. There is one in
