Hi Wayne,
Thanks for your help. Since I am using the API only to generate thumbnails,
I wouldn't have access to the plugin. I did however saw your code at
http://rsb.info.nih.gov/ij/plugins/download/Averaging_Reducer.java. Is
there a way I can just call the methods to clear the images? I believe
macros need to be run via the cmd shell, not java source. Is that the right
assumption?
Thanks,
Bilal

Try the Averaging Reducer plugin at "
http://rsb.info.nih.gov/ij/
plugins/reducer.html". If you can't use a plugin, try smoothing the
image, reducing it and then enhancing the contrast. Here is a macro
that does this:
run("Duplicate...", "title=Thumbnail");
run("Gaussian Blur...", "radius=2");
run("Size...", "width=100 height=100 constrain interpolate");
run("Enhance Contrast", "saturated=0.1");
