Hi Avital,
there's nothing wrong with the Javascript to Java array handling, as you
can see running the following script:
importClass(Packages.ij.IJ);
importClass(Packages.ij.plugin.RGBStackMerge);
imp1 = IJ.createImage("Untitled1", "8-bit random", 80, 80, 1);
imp2 = IJ.createImage("Untitled2", "8-bit random", 80, 80, 1);
imp3 = IJ.createImage("Untitled3", "8-bit random", 80, 80, 1);
var imgs = [];
imgs.push(imp1);
imgs.push(imp2);
imgs.push(imp3);
imgMrgd = RGBStackMerge.mergeChannels(imgs, false);
imgMrgd.show();
which displays an RGB image as expected.
When I change the dimensions of a single image, I get:
javax.script.ScriptException:
sun.org.mozilla.javascript.internal.WrappedException: Wrapped
java.lang.IllegalArgumentException: Dimensions do not match
(Script.js.js#12) in Script.js.js at line number 12
but I also cannot merge these images using 'Image > Color > Merge
channels...', the error is:
"The source images or stacks must have the same width and height."
Are you sure that your images impGFP, imRFP and impOutofFoc have the
same dimensions?
