This project is awesome.I admire the author's great effort on this project. But when i load dicom file of 12 bits uncompressed image file,it seems like losing some bits data.The edge of shape is very sharp with lots of white spots.But is fine with 8 bits dicom file.Is this a bug?How and when can be fixed? You can see it here.http://www.imagesocket.com/photos/guest/2461695

Yes, something doesn't look quite right there. Probably a bug of some sort. Will have a look at it and try to reproduce it. Thanks for the feedback!

I think I know why it behaves the way it does. The Pixel Representation is in two complement which is not handled correctly. Will close this issue and open a new.
