Try with kipi-plugins/digiKam 2.4... 1.9.0 is pretty old now...

I'm on Kubuntu 11.4. There is no newer packet than 1.9.0 are you positive this has been fixed? Kay Well, i cannot reproduce it, but it's better to see report author confirm it.

The tags in the TIFF are the same. the comparison is in this screenshot: http://dl.dropbox.com/u/52145569/misconverted.jpg and if you want the raw file it's http://dl.dropbox.com/u/52145569/IMG_3932.CR2 but it'll take a while to show up there since my uplink is slow Kay Ok, i tested result here with your image : It's the same in icon view. I tested with my Sony DLSR, it's the same with device autorotation settings. The problem is not with RAW converter. Look in metadata TIFF orientation tag is the same than CR2. If you disable thumb autorotate option from digiKam/metadta config dialog, TIFF will not be rotated The problem is about RAW preview image where we don't have any relevant information about rotation angle. The real image rotation information is not the same. It'is issue,s a big puzzle. The RAW preview is not taken from RAW data. It's an embedded JPEG image in RAW file. And orientation of this preview is not the same than RAW image, due to your change of your camera orientation settings. To solve this issue digiKam must be able to rotate thumbs independently of real image data. There is already a report in digiKam bugzilla about this subject...

If you disable thumb autorotate option from digiKam/metadta > config dialog, TIFF will not be rotated this is not so, at least not on my system. AFAIKT the raw processor here ignores the 'Orientation' tag and rotates according to the 'Camera Orientation' tag. Please note that my problem is that the image IS rotated, but I want it NOT to be rotated, this is why I have set the 'Orientation' tag to 'Horizontal'. And my issue is with the resulting TIFF file, not with the CR2 or it's display in digiKam. In hugin-ptx, where I am discussing the issue, I've been told that there were versions of dcraw which exhibited this bug, so I suppose that's what my problem is here. Of course it's possible that with your later version of the raw converter, the bug has been fixed already on your system. > The problem is about RAW preview image where we don't have any relevant > information about rotation angle.

I've checked by extracting the embedded JPG with dcraw -e. > The RAW preview is not taken from RAW data. It's an embedded JPEG image in RAW > file.

There is already a report in digiKam bugzilla about this subject... my problem isn't with the embedded thumbnail images. I process the data with hugin to make panoramas and I have a pretty good idea how to tell rotated image data from unrotated data. I need all the image data as it hit the sensor. dcraw, DPP and raw therapee all perform as I expect on this system. digiKam does not. Be assured the problem exists and has nothing to do with thumbnails or digiKam's thumbnail display. Kay I'm not quite sure which part is reading the CameraOrientation tag. It's a makernote tag, and I dont see it mentionen in libkexiv2. This bug is about the preview or the main image? I'm not quite sure after reading all the comments.

Images which have the Orientation tag set to 'horizontal' (and should therefore not be rotated) are nevertheless rotated if the CameraOrientation tag is not set to 'horizontal'. In RAW Import tool, Libraw check exif orientation flag. This is why in image editor i have disabled auto-rotation provided by libkexiv2 with RAW files. Gilles Caulier Kfj, This file still valid using last kipi-plugins 4.10.0 ? Gilles Caulier New Kipiplugins 4.11.0 is available : https://www.digikam.org/node/740 Can you reproduce the problem with this release ? Gilles Caulier RawConverter is not maintained since a while and is obsolete now. It will be removed with 5.0.0. Use digiKam BQM instead... |
