reading FITS files ? #38

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
I'd be interested in processing FITS files, a popular format in astronomy. FITS 
files are generally at least 16 bit scaled integers, or 32 bit, or more 
commonly these days, 32 bit IEEE floating point.
Normally you would get 3 colors, and have to combine them into a pretty 
picture, the kind you see on e.g. stsci.edu
A plugin called fits liberator gives a photoshop based method to combine three 
fits files into a color picture. With 8 bit gimp this is very challenging, but 
with the support for 16 bit (32 would be even better)
in photivo, a much better tool in open source would be available to the 
community which currently there is none really.

Probably cfitsio is needed to read fits files, and optionally wcslib to deal 
with sky coordinate systems.

I'm happy to discuss these options with the developers and see where i can help 
make this happen.

Hi, 

we use GraphicMagick for opening bitmaps, so it would be convenient if 
GraphicsMagick would support FITS (or does it maybe?). Also more people would 
benefit from another format in GraphicMagick. If not possible this way, we 
would need to include libs as you suggested... Since you are offering your 
help, do you want to implement it?

Hi mike
  thanks for the tip, indeed, GraphicsMagick does seem to support 
8, 16, 32 bit integer, float, and double FITS images.   The FITS liberator 
documentation has some nice examples and I'll try and reproduce that and see if 
there are any remaining problems. If anything, a nice demo will come out of 
this.

I would be happy about a small tutorial about Fits in Photivo if it works ;-)
