Hi Fred,
Please provide a small and runnable script or plugin that reproduces this
problem. The following script works as expected. There is no scaling and the
display range
does not change.
-wayne
imp = IJ.createImage("Untitled", "16-bit ramp", 512, 512, 1);
ip1 = imp.getProcessor();
ip1.multiply(0.5);
ip1.resetMinAndMax();
imp = IJ.createImage("Untitled", "16-bit ramp", 256, 256, 1);
ip2 = imp.getProcessor();
ip2.multiply(0.9);
ip2.resetMinAndMax();
IJ.log("");
IJ.log("ip2 range: "+ip2.getMin()+"-"+ip2.getMax());
IJ.log("ip1 range (before): "+ip1.getMin()+"-"+ip1.getMax());
ip1.insert(ip2, 128, 128);
IJ.log("ip1 range (after): "+ip1.getMin()+"-"+ip1.getMax());
new ImagePlus("ip1 after insert",ip1).show();
