Using circular ROIs with XOR

B.W. Basheer
Hello,

I'm new to ImageJ.  Am trying to use xor on the pixel values within the bounds of a circular ROI.  The Javadoc documentation says XOR operates on all pixels in the image or an ROI.  In my tests, the XOR method is operating without regard for the boundaries of the circular ROI.

By way of example, I'm trying it this way:

image.setRoi(new OvalRoi(0,0,2950,2950));
image.getChannelProcessor().xor(0xffff);

Thanks for any suggestions.  It would be greatly appreciated.

Cammer, Michael-2
I'm not sure what youare trying to do, but maybe something like this in the macro language?


  open("http://microscopynotes.com/cd11c_spleen.jpg");
  makeRectangle(0, 0, 282, 108);
  run("Crop");
  run("Split Channels");
  selectWindow("cd11c_spleen.jpg (red)");
  makeOval(76, 9, 88, 88);
  run("Copy");
  selectWindow("cd11c_spleen.jpg (green)");
  setPasteMode("XOR");
  run("Paste");
  run("Select None");
  run("Merge Channels...", "c1=[cd11c_spleen.jpg (red)] c2=[cd11c_spleen.jpg (green)] c3=[cd11c_spleen.jpg (blue)]");
