Philippe, This file still valid using kipi-plugins 2.4 ? Gilles Caulier
opensuse 13.1 , kde 4.12 , digikam 3.5 libkipi 2.1.0 libPNG 1.6.6 Modules externes Kipi 3.5.0 original image 765,8 ko png 1 9 MB png 7 4,8 MB png 9 4,8 MB original image 3.2 MB png 1 23.1 MB png 7 7,8 MB png 9 7,5 MB pb solved but a new pb : jpg portrait mode ----png convert --> png in landscape mode ! if compressor is unable to compress more than 7 for this image
do not take care of the last sentence in the previous comment
The portrait orientation must be preserved by Exif copy from JPG to PNG, done by ImageMagick (or GraphicsMagick) used in background. If it's doesn't work, it's an IM problem. In all case, this kipi tool is obsolente now, since conversion can be done into digiKam BQM as well. Gilles Caulier
when in digikam using png convert jpg photo in portrait mode ----png convert --> png photo with thumbnail , preview , editor view in portrait mode . good . but in dolphin thumbnail , preview in data panel are in landscape mode . i will made a new report i close this report

IM ==> ImageMagick BQM ==> Batch Queue Manager Dolphin thumbnailer is KDE module, not digiKam thumbnailer. Report this problem to Dolphin team. Typically, KDE thumbnailer is not able to read Exif from PNG as digiKam do. It's must not be a problem if they use Exiv2 shared library through libkexiv2 Gilles Caulier
Is "EXIF in PNG" a standard? Stackoverflow says no: http://stackoverflow.com/questions/9542359/does-png-contain-exif-data-like-jpg
yes it is, as non standard, but IM, exiftool, and Exiv2 can manage it (i presonaltly implemented it to Exiv2). Only XMP is standardized by Abode with PNG. The idea is based on IM wait. Simple to test : # convert foo.jpg foo.png # convert foo.png foo2.jpg Now compare Exif from foo.jpg and foo2.jpg. Note IPTC is also saved in PNG by the same way by IM Gilles Caulier
