drawing canvas over microscope image #2
Description
We would like a drawing canvas over the microscope image so that you can doodle onto the image to display the location of an optical trap, or provide guide lines for yourself of how you want to line things up, or to put up grid lines for approximate measurements.
This ideally would be in a color (e.g. red), not black and white.
More simply, we could provide a limited variety of shapes and hack the image so that certain pixels are red in the display (but NOT in the saved raw data!!!!)
Uses sometimes want to save the drawn items with the raw data--- but this should NOT be the default!!!!
