Ok, i cant get this to work at all. Do you think it would be possible for you to write a quick example program for me?

Thanks,
Mark

Hi again Mark,

OK,

here is a simple example, if ip is a reference to the underlying
imageprocessor with the selection do

      ImageStatistics stats = ImageStatistics.getStatistics(ip,
ImageStatistics.AREAFRACTION, null);

to get a reference to the statistics Object. The second arg is actually a
"bit map" that allows to specify a combination of the statistics you try to
retrieve.

After this,

      stats.areaFraction

has what you are looking for.

Again, for the documentation, look here:

Hope this helps

Sincerely

Joachim Wesner
