Hi, say for example i have a binary image which is just a simple black blob on a white background, i have a random centre and i would like to find the distances from the centre to the edge of the blob at different angles, say at about 30 degrees between them.

Any ideas on how best to go about this? Any help would be much appriciated.

Thanks,
Mark
