Hi All
I've written a simple plugin to normalise pixel values, making a new
8-bit normalised copy of the original 16-bit DICOM image.
When I try to run the plugin, IJ complains, saying that the image is
locked. If I try to unlock it (Plugins->Utilities->Reset...), ImageJ
tells me that the image is not locked. What can I change to make this
plugin work?
Cheers
Mike
