Dear all,

I got a binary image of borders of particules (black borders surrounding
white area, white general background). The borders may be connected, but
I want unconnected area. So, I inverted the image to get white borders
and black holes. Every area should be now be well separated. But, the
background is also black. So I am trying to fill the background with
white. Unfortunately the color fill tool or the wand tool fills/selects
the whole image and don't stop at particules borders. Any idea?

Regards,
Samuel
