Description

Wish: It will be nice to have Canon RAW CR2 files (TIFF based) write support in Exiv2. I own Canon EOS DSLR camera and work using digiKam (which use exiv2) with those CR2 files and it is very uncomfortable when I haven't got possibility to write tags, geolocation and other metadata into files. I must use other tools, such as ExifTool.

History

#1 Updated by Andreas Huggel about 8 years ago

  • Target version deleted (1.0)

#2 Updated by Andreas Huggel over 7 years ago

  • Target version set to 0.20

#3 Updated by Andreas Huggel over 7 years ago

CR2 images have a header with a pointer to the last IFD.

#4 Updated by Andreas Huggel about 7 years ago

  • Target version changed from 0.20 to 0.21

#5 Updated by Russell Harrison almost 7 years ago

I would like to second the request for this feature. For instance when I tag my raw files in digiKam its quite tedious to have to retag after processing the raw files.

#6 Updated by Daniel M√ľnch almost 7 years ago

Oh yes please, I am using igikam as well and really have problms organizing my RAW files because I can't write tags and ratings

  • Target version changed from 0.21 to 0.22

#8 Updated by PC Guy over 6 years ago

I will like to see this feature as well, mostly for Rusell's reasoning as it will CR2 file first class citizens in digiKam, as there is no way (currently) to use exiftools with digiKam for CR2 write support. I hope it gets into 0.22 and will not be bumped again to next version ;)

#10 Updated by Aleksandr Bagmut over 5 years ago

At what stage of development is support of writing into CR2? And when you plan to add this feature?

#11 Updated by Andreas Huggel over 5 years ago

  • Assignee set to Andreas Huggel

I've added some experimental code to write to CR2 images, finally. Ufraw (i.e., dcraw) can still open a modified image and the OSX image viewer still shows the image (not sure if that's only a preview though), other than that I've not tested it, in particular I do not have any Windows or Canon software to check.

Please check-out the latest trunk version to test and report your success back here. Do make sure you have a backup of any images you test with!
