We stumbled upon a problem with screen capture module. After loading the data in 3D slicer, we wanted to save the R, G and Y view planes that we set into the system. We used Screen capture module, but noticed that the resolution of the images being saved depends upon screen size of my 3D slicer app window, or the view window inside the app itself, how much I have expanded or shrinked that particular view. This creates a problem of reproducibility.
We are trying to extract slices from our CT volumetric data along different planes set at arbitrary normals and center points. As we find a suitable plane along a normal and we can subsequently view them in slicer views, we were trying to save them. But looks we have to remember a constant window size at which all the slices were saved using screen capture so that, in order to reproduce them anytime.
Why are they not saved at the resolution of original dicom files ? Am I saving it the wrong way ?
Also, we would prefer if we avoid saving it as PNG images as it compresses the images down to 8 bit depth while my original dicom images are of 16 bit depth per pixel, may be saving as numpy would be better ?
Kindly guide to fix the issue. Would be lot helpful.
