Loosing all Metadata when editing

Loosing all Metadata when editing
 
|
I am loosing all metadata when I edit an image with the built-in editor or Showfoto and do a save-as.
I have processed the images as follows: Convert from .cr2 to .png using the Batch Raw Converter tool (after this the metadata is still there); Geotag (after this the metadata is still there); Edit using F4 or Showfoto - I have done free-rotate and color adjust, and just color adjust) Save as .png with a new name. After the save all the metadata is gone. I get an error if I try to import the metadata from the original converted .png I have done the editing sequence using Photoshop Elements 4.0 Editor (installed with WINE) and with this the metadata is preserved. Has anybody run into this?

Yes, me too. I processed around 130 RAW photo in editor (ARW to PNG), and sometimes, metadata are lost. It's not reproducible each time. I take a look in source code and PNG writter has the right code to backup metadata with Exiv2. I suspect something like this : i use a tool in editor and metadata are lost at this time, but still displayed in right side bar. You see the lossy action after to save and take a look back in target file. I process my RAW files like this : Raw import tool, ratio crop, free rotation, and sometimes some color correction tools, as B&W. I don't use CM there. As developer, i use all code from trunk, kdegraphics/libs, digiKam and exiv2. kipi-plugins is not used there. Can you confirm this ? Another point : can you reproduce this dysfunction if you save your RAW image in TIFF or JPEG ? It can be interresting to see all debug messages from a console, when you process a raw image. I recommend to open a new file in bugzilla about.

I'm not sure what code bases are being used (I am using a standard Ubuntu 10.4 installation (32 bit) with DigiKam installed with the Synaptic Package Manager).
There seems to be some irregularity with the problem - not occurring the same way all the time - but since I have been verifying step by step I have not isolated anything other than I described in the first message. I did discover that if I save as .jpg after doing the edits that the metadata is preserved. I have been using this as a workaround and it has been stable. I'm going to try other formats and look into filing a report in bugzilla.

Any debug trace if you run digiKam on a console ?

When I run Digikam in a terminal window there is a lot of output to the window. Is that the debug info that you mean? I'm not too familiar with this kind of stuff.
I have been trying to isolate conditions where the problem is occurring and I am getting bogged down in too many possibilities. I have converted to ppm and png and dng and get different results. I have used the Digikam converters and stand alone and seem to get different results. I am going to try to build a matrix of conversions x results and I will post them when I can.
