Comments on PNG problem from Rawstudio developers

Description David Vincent-Jones 2010-11-25 19:09:16 UTC
Version:           1.4.0 (using KDE 4.5.1) 
OS:                Linux

Digikam is unable to display any metadata from images produced by other programs.

Images produced out of Cinepaint, Rawstudio etc and imported into DK are missing EXIF and other metadata. I carefully tested using exiftool that the metadata was correctly in place prior to trying the import.

Rereading the metadata within DK does not help nor rewriting metadata to all images.

Reproducible: Always

Steps to Reproduce:
Using a raw file in DK, use 'open with' either Cinepaint or Rawstudio, process to png format and save back into DK folder. ... or Directly process raw file in outside editor and later import into DK

Actual Results:  
No metadata from any 'foreign' image processing is displayed in DK.

Exiftool reports that all image data is correctly in place in test files.

Expected Results:  
Should display all metadata as produced by external editors.

OS: Linux (i686) release 2.6.35-22-generic-pae
Compiler: cc

Please provide a sample image
Comment 2 caulier.gilles 2010-11-25 20:23:29 UTC
digiKAm use Exiv2 library to handle metadata. 

Try to parse image file with exiv2 command line tool to see if Exif info are there...

This is output from exiftool. Small cut from raw data processed in
Rawstudio. No EXIF (or other metadata) data shown in DK. when file is
imported.

New information however:

JPG file does appear to work correctly, EXIF looks correct in DK .... 
PNG file does not work .. nothing shown in DK

Comment 4 Marcel Wiesweg 2010-11-25 23:02:12 UTC
There is no information necessarily from Exif in this output. It's file info and PNG image info.
Comment 5 David Vincent-Jones 2010-11-25 23:16:44 UTC
I cut short the full extent of the very long EXIF data for brevity but
if you like I can provide the full file.

Comment 9 David Vincent-Jones 2010-12-04 21:56:18 UTC
Further Tests:
Opened RAW image in DK and wrote to TEST1.PNG format. All EXIF data correctly in place.

Opened the above TEST1PNG in Rawstudio, modified it and wrote to new PNG file. Exif data correctly modified and complete.

Opened TEST1.PNG in Cinepaint, modified it and wrote to new PNG file. NO EXIF or other metadata displayed in DK.
Comment 10 Martin Klapetek 2010-12-05 01:21:11 UTC
Thanks for all the info, but please do provide us with some test image, so we have something to test the eventual fix on. Either upload it here as an attachment (down below is the form for that, but be aware that there are size restrictions) or upload it somewhere else from where we can reach it. Thanks!
Comment 11 caulier.gilles 2010-12-05 07:41:16 UTC
Is the new P?G file processed by RawStudio respect metadata standard place ?

Open it with Exiv2 command line tool, and look if Exif/iptc/xmp metatada are visible.

digiKam do not use Exiftool (perle program), but Exiv2 shared library which is C++.

Comment 12 David Vincent-Jones 2010-12-05 18:17:36 UTC
This appears to be the problem: Exiv2 is NOT reading the information and Exivtool is reading all of the information on PNG format images. This appears to be the same situation with exports from Cinepaint.

However it is also strange that DK is able to read the metadata in JPG and TIF files written by these other programs.

Do you see this as a problem in DK or other program export formats?
Comment 13 caulier.gilles 2010-12-05 23:32:38 UTC
it's definitively a problem with Exiv2 library.

Please provide a PNG image sample to test.

Comments on PNG problem from Rawstudio developers
Comment 16 caulier.gilles 2010-12-06 19:32:21 UTC
Rawstudio developer said that PNG do not support Exif... This is false...

PNG support XMP which can embed Exif metadata. It's a recent specification from Adobe.

digiKam support this way, but also another one which consist to use a iTxt PNG chunck as ImageMagick do. Try :

convert foo.jpg foo.png
convert foo.png foo2.jpg.

And look like Exif from foo.jpg and foo2.jpg are the same.

Exiv2 library, which is used by digiKam to manage metadat use this way... I'm sure i implement this code myself.

Rawstudio, must use a decent library to play with metadata, as digiKam do...

This is not the fault of digiKam if other photo tool software are not able to manage metadta on the right way. Sorry to make digiKam better...

The exiv2 command line tool DOES extract Exif data from the attached image.
