Re: [Gimp-developer] EXIF information in JPEG files
Hi Lutz, I have written an EXIF library in plain C (libexif) and some GTK+ widgets for displaying and modifying EXIF data (libexif-gtk). Both are available on http://libexif.sourceforge.net. I use them to display EXIF tags in gphoto2 (command-line frontend) and gtkam (GTK+ GUI). Thereare a couple of other libraries which do pretty much the same thing - see the relevant bug numbers in bugzilla (not sure what they are right now). I haven't had a chance to look closely at this, but it looks good. However, when loading images from a digital camera directly into gimp and letting GIMP save the images (i.e. as JPEG files), all EXIF information gets lost. In addition, right now, gimp doesn't offer access to EXIF information when loading JPEG files. Yup. We use a straight call to libjpeg's header parser, which doesn't know anything about exif. A couple of people (myself and Raphael Quinet) were looking at this with a view to adding support in 1.3 at least about a month and a half ago. Then I moved to France, and that got put on the back burner, and my computer's still in storage. The last I had done was a very simple hack which replaces our call to the header reader with a call which read exif information. The next step would have been to specify how that information would be passed over and back between the main gimp and the jpeg plug-in. There was some discussion on this, and it was agreed by everyone (eventually) that parasites were the way to go. So all we need to do is define what information would be available in the exif parasite, and how to get at it. I spent a bit of time at this writing up a short RFC, but it was pretty scattered, and never got finished/posted to the list. How do I go about adding EXIF support to gimp? Should I distribute a loader for JPEG files that replaces the current one? Submit a patch to gimp's JPEG loader and configure.in to --enable-exif if libexif(-gtk) is installed? If you write a wee report which says what exif information you get out of the file, and read up on parasites (which is about where I was at 6 weeks ago), post a mail to the list with reccommendations, and then code whatever comes out of the reccommendations. Until my computer comes out of storage (15th of February) I'll be useless to you, but there are otehrs who were interested in doing this too. There was a proposal before to have an exif data editor (or even a parasite editor) as well, but I reckon the first step is getting the exif stuff read into some well-defined structure, and getting it written out to files in the same proper structure without destroying it. If we can do that, a generic parasite editor can handle the editing of the metadata. In any case, how do I save per-image (not per-loader) EXIF data? I'm not sure what you mean by this...

EXIF information is specific to JPEG files. Therefore, editing and storing EXIF information make sense with JPEG images only. Sure, you could try to save/hide/convert it in other image formats, but this is not the purpose of the EXIF specification. EXIF is specific to JPEG files, but you find almost the same information in the TIFF/EP format. So we should try to have a generic solution for the GIMP, that is not limited to EXIF only. If you look at bug #56443 and have a look at the proposal for adding EXIF support to the PNG file format (http://pmt.sourceforge.net/exif/index.html), you will see a long table that describes how the individual fields can be mapped from one file format to the other. That's why I wrote in my previous mail that all data should be saved in GIMP parasites, because that would allow each file plug-in to import/export the parts that are appropriate and discard or convert the rest. So we should be able to have something like this: Load JPEG/EXIF file - GIMP parasites - Save TIFF/EP file -Raphael ___ Gimp-developer mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-developer
