Hi there Everyone,

I have someone who is loading tif images into our MITK based app, and is asking 
questions.

Please can someone describe the correct handling for .tiff images, and RGB 
images in general? 

Bugs 1823 and 12811 suggest that tiff images are not supported, but .tif is 
listed as a valid file extension.

But what should the initialisation of the min and max intensity be? How should 
the Window/Level be set?
At the moment it looks like the Window/Level defaults to 255/127… which seems 
reasonable.
But is this valid or relevant for an RGB image? I am more used to working with 
single channel images.

But then when I play the Window/Level widget, the display changes …. but if 
this is an RGB image, what colour map is being used to create the observed 
visualisation contrast changes?  How should you map an RGB image through a 
lookup table?  I thought RGB would just be copied to the screen, so that 
changing the Window/Level would have no effect.

My lack of understanding is probably made a bit more pronounced than usual, due 
to the fact that the images I am looking at have equal RGB channels, and so 
appear greyscale anyway!!!!
:-)

Any help would of course be appreciated.

Thanks

M
