Which version of exiv2 do you use (see the Help/About digikam/About)? What does exiv2 DSC_0006_digikam.png show? Arnd, Here, this is not the fault to Exiv2, but KDE API and especially KFileMetaInfo... Look in the code, at digikam/libs/imageproperties/imagepropertiestab.cpp, line 468 KFileMetaInfo do not search Exif info in PNG for that. It scan whole file to find PNG Chunk witch include image informations (PNG ImageHeader Tags : http://www.sno.phy.queensu.ca/~phil/exiftool/TagNames/PNG.html#ImageHeader). It's completly different than the way used by Exiv2 witch do not know (yet) this chunk, but only try to find the text chunk used to embed Exif informations as a byte-array (same for IPTC and XMP). Of course i can patch Exiv2 for that... But this is not the real problem here. Now try to parse this image with exiftool like this : exiftool -g DSC_0006_digikam.png ======== DSC_0006_digikam.png ---- ExifTool ---- ExifTool Version Number : 7.00 Warning : Bad NikonPreview directory ---- File ---- File Name : DSC_0006_digikam.png Directory : .

Only on Exif byte array, not on PNG ImageHeader Tags... Conclusion : i suspect than : - this file is corrupted or uncomplete (where are dimension and compression infos ?) - and something is wrong on KFileMetaInfo (why at least Bit Depth and Color Type are not found ?) Gilles Oups, wrong exiftool console output, sorry. this one is better :

digiKam for KDE4 vs gimp
Ar,
Look like the problem diseapear with digiKam for KDE4, where KFileMetaInfo is not used anymore...
I close this file now.
