#32 Request inclusion+documentation of lenstool in tarball

[Walter Dnes]

I've posted about this on the mailing list, but since I'm now going to ask for a "feature request", I assume that this is "official channels". Please forgive me if I'm missing something obvious. Right now, if I shoot 100 or 200 photos in a day, and they require lensfun correction like http://www.dpreview.com/forums/post/51970815 it has to be done manually 100 or 200 times...

• load CR2 file in GIMP and select OK
• go to "Filters ==> enhancement" in GIMP, and select gimp-lensfun
• click OK (it seems to read the Exif data correctly by default)
• repeat 100 or 200 times (painfull)

Lenstool http://lensfun.sourceforge.net/manual/lenstool_8cpp-example.html looks like it might be what I need to do it at the command line. Can you provide documentation/makefile/whatever to build lenstool as part of the lensfun library tarball? And also a short example of how to use it, e.g. something like...

lenstool input_file output_file parm1 parm2 parm3

For now, my only need is to correct the "barrel" distortion in the Canon s100 CR2 files. Note the pole at the right-hand edge of the sample picture pointed to above. I have the perl "exiftool" utility installed, which can read EXIF data from the raw file, for use by lenstool. I'm not a programmer, but I can compile a program, given instructions. My main worry is that the latest lensfun on Gentoo linux is 0.3.0 and the lenstool code is for 0.3.1.0. Are they compatable?
