Note that in Gimp 2.1 the exif data parasite has been renamed "exif-data", because it is not specific to jpeg files.

Re: [Gimp-developer] Howto: store comments in image from plugin?
Thanks for all the people who answered. It turned out to be as simple as attaching a "gimp-comment" and "jpeg-exif-data" parasites to the image. (of course generating jpeg-exif-data is not trivial. Only implemented for my Nikon D70 at the moment. I guess others who like more formats will have to implement their own) -Joseph ___ Gimp-developer mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-developer

Hi, Joseph Heled wrote: I would like to "attach" to the image some of the parameters of the conversion. The GIMP uses a mechanism we call parasites to attach data to an image. A good example of their use is in the jpg plug-in, for example, where we attach exif data, a comment and also save parameters. A complete list of "standard" parasites, and a short description of teh parasite mechanism, is in devel-docs in the GIMP sources. I am not sure , - How do I add this info to the image (I open it with gimp_image_new(...) ) - Which file formats support this kind of comment/data? png, tiff, jpg all support exif, iptc is supported by tiff and jpeg as well, there are lots of other metadata formats which are supported by various formats. I'm not quite sure. On a related issue, how can I add EXIF data to the image? Perhaps I can add some data in the EXIF comment? We link to libexif already, and use it in the jpeg plug-in. You can construct an exif header and write it to a file in the same way as we write the exif header back to the file now. libexif is available here: http://sourceforge.net/projects/libexif Cheers, Dave. ___ Gimp-developer mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-developer

[Gimp-developer] Howto: store comments in image from plugin?
(I hope this is the appropriate forum ...) I am developing a plugin which loads raw images from digital cameras (CRW,NEF etc). I would like to "attach" to the image some of the parameters of the conversion. I am not sure , - How do I add this info to the image (I open it with gimp_image_new(...) ) - Which file formats support this kind of comment/data? On a related issue, how can I add EXIF data to the image? Perhaps I can add some data in the EXIF comment? I would appreciate any help/ideas ...
