Dear all,

 

I'm trying to make a selection around segmented particles (with a black background). When I make the normal selection, there is no problem and the selection follows the outline of the particle, but when I select it as a polygon, on many particles, I get a rectangle instead of the outline of the particle.

Does any body have an idea why? Is it possible to get this polygon selection properly?

 

Thanks,

 

France

 

 

This is what I'm doing:

 

setThreshold(1, 255);

run("Create Selection");

run("Enlarge...", "enlarge=0");

getSelectionCoordinates(selX, selY);

run("Select None");

makeSelection("polygon", selX, selY);
