I'm writing a plugin and like to get images from a stack.
The stack is float, but I'm not able to get float images out of it.
Here is some sample code extracted from my application:
IJ.run("LSM Reader", "open="+dirname + System.getProperty("file.separator") + children[i]);
ImagePlus imp = IJ.getImage();
IJ.run(imp, "Split Channels", "");
IJ.selectWindow("C1-"+children[i]);
ImagePlus blueimp = IJ.getImage();
IJ.run("32-bit", "");
IJ.selectWindow("C2-"+children[i]);
ImagePlus yellowimp = IJ.getImage();
IJ.run("32-bit", "");
C1 and C2 are 32 bit !!
ImageStack bluestack = blueimp.getStack();
.....................
blueip = bluestack.getProcessor(slice);
Rectangle roi = blueip.getRoi();
ImageProcessor fblueip = new FloatProcessor(roi.width, roi.height);
fblueip = blueip.convertToFloat();
..............
ImagePlus testim = NewImage.createFloatImage("RatioIm",roi.width, roi.height, 1, NewImage.FILL_BLACK);
testim.setImage(fblueip.getBufferedImage());
testim.show();
This gives me an 8 bit image.
Thanks,
Gerrit
