Use Fitsviewer for Raw statistics (Canon,Nikon,...) - by: pauledd

With Linux I found it very annoying to get reliable image statistics from images acquired during a kstars session (native image format).
Sometimes I want to review captured raw files for proper exposure but the current window that opens when a raw has been captured
does not reflect the true exposure, please correct me if I am wrong, it shows the (*.cr2) embedded thumbnails that is a jpg with nonlinear
representation of the light.
It would be very "cool" to have the native images also shown in the fitsviewer and also with detailed image statistics like mean/min/max/std.dev.
It is quite hard to get those statistics in linux via command line from a cr2 file (please enlighten me how you do that(without huge apps like PI)).
I currently use imagemagicks "identify -verbose" to do that to get a huge list of statistics and I have to do a:

to get only whats interesting. Moreover that is terrible slow (50 seconds) for unknown reason(*).
