[Gimp-user] ufraw/lensfun

[Maurizio Loreti <maurizio loreti gmail com>]

Hello, list -
I am a satisfied GIMP user, and I am using the skl's "Mac on OS X" 2.8.10p2 release running under OS X 10.9.4.

I have problems with the "lensfun" corrections to my photo pictures; I am not sure if this is related to GIMP 
itself, or to the Mac port I am using.

What happens is:

if I open a Canon RAW image (a CR2 file), GIMP recalls the "ufraw" plugin window; in the third tab ("Lens 
Correction"), ufraw does not know my camera Canon 6D, nor my other camera Canon Powershot G15, nor my lens 
Canon 24-70 EF L II (note the "II"), nor other lenses I have.
If I open a Canon JPG image, the plugin GIMP-Lensfun v0.2.3 (Filters -> Enhance -> GIMP-Lensfun, inserted I 
think in the distribution by skl) does not know the same cameras and objectives.

The lensfun correction files are shipped by skl in the directory 
/Applications/Gimp.app/Contents/Resources/share/lensfun/ , and are named compact-canon.xml and slr-canon.xml.

I have tried do download the last versions from the lensfun distribution, now hosted on sourceforge; under 
the URL http://sourceforge.net/p/lensfun/code/ci/master/tree/data/db/ there are three files canon-related, 
named compact-canon.xml, slr-canon.xml and mil-canon.xml.  Just copying the first two files, or all three, on 
my GIMP tree, makes GIMP choke on the format of these files - both for RAW images and for JPG images; 
probably the xml file format has changed with the time.

QUESTION: how can I upgrade GIMP so that it will use modern and complete lensfun files?
