Here is an example:



The vertical white line is the profile I wish to draw. The brightness of the image is proportional to the chemical composition of the crystal, except where there are cracks.  I would like to draw round the cracks, and the get ImageJ to ignore the values of any pixels within those areas.

Thanks!
