old style jpeg support

[mick-21]

Dear all,

As far as I can tell this is not a digikam error however I am trying to
use digiKam to manage my photos and it is unable to open some tif files.

I am hoping there is somebody who has already solved the problem and can
help me out.


I am unable to view some scans made on a FujiXerox scanner and saved as
tif's.  In digiKam the exif metadata is reporting "compression
(old-style)".

After doing a quick bit of research it seems the problem may be with
libtiff and I may have to recompile or enable old style jpeg support in
libtiff.

Any suggestions or solutions.

Thanks.

Mik,

Yes, you need to recompile and install libtiff with the right codec support.

I recommend to use another file format as PNG which is more supported under Linux. Also, PNG is  lossless and support all metadata (Exif, iptc, and xmp).

Thanks Giles,

I'll do that.

At the moment I have a few things that have been scanned as tiff (old
style jpeg) on the same scanner and its only options are tiff or pdf.
I'll convert to png when I get the libtiff recompiled.

Thanks.

Another alternative is to use ImageMagick like this :

#convert foo.tiff foo.png

But like ImageMagick use libtiff, you will seen a similar problem. If no, let's me hear. I will take a look using a picture sample from your collection...
