Re: [Gimp-user] Questions about EXIF data (Windows version)

 Von: perkin-warbeck for...@gimpusers.com

 I'm sending tiff files to GIMP (version 2.6.7 for Windows) from a raw
 converter.  The tiff files contain a lot of EXIF data such as Fnumber,
 FocalLength, ExposureTime, ISO. and so-on.  When I save as jpeg from 
 GIMP, most of the EXIF data is discarded.  In the Save as JPEG dialog,
 the checkbox Save EXIF data (under Advaned Options is unchecked.
 It is grayed out so I cannot check it.

The Exif data is discarded when opening the TIFF files. So far, only the JPEG 
plug-in reads and saves Exif data from and to image files.

 Here are my questions: (1) Is the Windows version of GIMP packaged with
 libexif? 

Yes.

 (2) If not, is there a workaround?  

A workaround is to use a different tool - e.g. exiftool - to extract the Exif 
data from the original files and add it back to the resulting files.

A fix would be to add Exif support to more file format plug-ins (e.g. TIFF, PNG 
and possibly others).


Regards,
Michael

Thank you, Michael.  You solved my problem.  I was able to import EXIF data 
using ExifTool.

In Chapter 6 of the GIMP manual, it says

Although GIMP uses the “libexif” library to read and write EXIF data, the 
library is not automatically packaged with GIMP. If GIMP was built with libexif 
support, then EXIF data is preserved 

Here are my questions: (1) Is the Windows version of GIMP packaged with 
libexif? (2) If not, is there a workaround?
