Hi everyone,
I'm writing a little plugin for imageJ and I am drawing several regions as an overlay on the image.
I'm using this code:
ImagePlus imp = getImage();
Overlay ov = new Overlay();
for (int r=0; r<regions.length; r++)
{
ov.add(regions[r]);
}
imp.setOverlay(ov);
Where regions
is an array of Roi.
This works as intended and draws the regions in the (hurting to my eyes) standard ImageJ cyan used for overlays. I would like to draw one particular region in another colour, but I cannot seem to find a way to do it. I found that you can change the colour of the whole overlay, but I need two colours in the same overlay.
Any ideas?
Thanks in advance
nico
