I'm using ImageJ as an API in my own Java software.  It's a GUI-less program for use in batch jobs.  I can read a FITS image in, resize, annotate with text and write it as a PNG.  What I can't do is:

Write as a GIF:

The GIFWriter operates in GUI mode on an open image.  Can I use this from my GUI-less program?  Or another GIF Writer from someone?

Use a Lookup Table:

I can't figure out how to read one of the LUTs distributed with ImageJ and apply it to an image.  

Is a LUT turned into a LookupTable and applied to an ImagePlus?  I see a method to get a LUT from an ImagePlus, but not to set a LUT.

Is a LUT applied when writing a specific file format?  Read the Lookup Table, convert it to a format specific to a particular image file and set it in a Writer?

Thanks for your help.
