Hi,

what I want to do is:

Open a DICOM-File, create a ROI and save only this ROI as a TIFF-Image.

Doing this by using the GUI of ImageJ is simple and not the Problem.
My Problem is:

I want to use the ImageJ-API. I tried to use Code like this:

ShortProcessor sp = new ShortProcessor(width, height);
roi.drawPixels(sp);

ImagePlus ip = new ImagePlus("", sp);
FileSaver fs = new FileSaver(ip);

fs.saveAsTiff();

But I can't open the resulting Tiff-Image. Whats wrong with this Code?
Do I have to convert the DICOM-Image before saving?

Thanks for help,

Guido
