Call maximum threshold?

[moxed]

Hello, I'm writing a macro in the ijm language.

I'd like to set the threshold of my image as 10% of the maximum and the maximum.
Something like:
setThreshold(0.1*max, max);

However, I'd like imageJ to automatically detect the highest threshold of my image. I can't figure out how to get this information without setting it manually.  Any ideas?

Thanks in advance!

Hi Sam,

Do you refer to the maximum pixel value in the image? This is what determines the maximum in the histogram of the Threshold panel.
You can get it with getStatistics:

  run("Select None");
  getStatistics(nPixels, mean, min, max);
  setThreshold(0.1*max, max);
