Programmaticly applying an LUT to an ImagePluse

[Robert Lockwood]

I'd like to try to apply an LUT such as "fire" to my very low contrast 16
bit unsigned ImagePlus.  The image displays very well using the below code:

        ContrastEnhancer ce = new ContrastEnhancer();
        ce.equalize(imp);

I've not been able to find an example using Google so have come to drink
from the well of knowledge again, Thanks.

Hi Nate,

'Fire' (like the other LUT names) is a menu command, so you can use the macro recorder in 'java' mode.  You can also use something like
  IJ.run("Fire");
or, if you want to specify an image (which need not be the foreground image)
  IJ.run(imp, "Fire", null);


With Plugins>Utilities>Find Commands, you can also find the class responsible for this command, which is ij.plugin.LutLoader.  Looking at its source, I suspect that something like the following will also work for the current foreground image:
  new LutLoader.run("fire");

I had found LutLoader but didn't see how to use it.

I think I should have mentioned that I am displaying my images on a
JImagePanel.
This works and the Fire LUT is great for my demonstration until I can
construct a custom LUT.

ContrastEnhancer ce = new ContrastEnhancer();
ce.equalize(imp);
IJ.run(imp, "Fire", null);

Thank you kindly,

Nate
