[Bug 237246] New: Erratic TIFF thumbnail generation, some crashes

[Paul Verizzo]

https://bugs.kde.org/show_bug.cgi?id=237246

           Summary: Erratic TIFF thumbnail generation, some crashes
           Product: digikam
           Version: 1.1.0
          Platform: unspecified
        OS/Version: MS Windows
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:           1.1.0 (using 4.4.00 (KDE 4.4.0), MS Visual Studio 2008 SP1)
Compiler:          cl.exe
OS:                Microsoft Windows (i686) release 5.1 (XP Professional)

I have a fair number of TIFF images, either from RAW or in-camera generation.
Most of them open just fine in digiKam, but others don't.  All I get is an
image of a balloon.  

I've looked for the common denominator(s)like size, 24 or 48 bit, but can't see
one.  The only pattern is not even perfect: some folders open better than
others.  But I've had several in a folder display and the others don't.  

One small folder of 48 bit images, upon trying to open, crashes digiKam.  I get
a generic C++ runtime error message.

I recently got digiKam running on my Knoppix USB stick.  Everything seems much
more stable running in Linux. I'll check on this particular bug the next time I
fire up Knoppix.

I would love to, but it's not there for Windows yet....as I'm sure you know.

Related to this is my wondering why digiKam MUST run on Windows KDE.  I think
that's where a lot of the issues I'm experiencing are coming from.  Windows KDE
also installs, without option, about two dozen KDE programs that have nothing
to do with digiKam and that I will never, ever use.  

The GIMP and XnView, to name two programs I'm familiar with, don't require KDE.
 Please?

FYI, THANK YOU (and the other contributors) for digiKam!  Despite lots of early
head banging problems with the scan, I saw through that to the potential.  And
it then "made me" spend untold hours trying to do something with Linux to look
at the native environment.  I tried Ubuntu Wibu, Ubuntu in Virtual Box, Knoppix
off of CD.  I bought an 8GB thumb drive and installed Knoppix to it which
allowed me to save all settings - and install/run digiKam.  

digiKam = Adobe Lightroom at a savings of $299!

The TIFF format offers a choice of different options to store and format the
file. Not all of them are currently implemented in digikam.
Additionally, while libtiff provides support to load all these formats as 8bit,
digikam wants to open a 16bit image as 16bit, which means we cannot use the
libtiff convenience code, and there are a few flavors of TIFF not supported
(while other application just open them, based on 8bit)

I can't speak to TIFF options, but none are compressed.

The ones in the "48 bit" folder were scans of color negative film and have a
file size of 178mb.  If my scanner has TIFF options, I did not elect any.

Others, quite old, were made in camera.

The above mentioned folder that crashes digiKam on Windows has NO problem
within Linux.

In fact, digiKam is two different beasts depending on the OS. Fast, reliable,
fast to scan even from scratch in Linux. (45,000 images) Many problems in
Windows, including inability to scan a particular folder (it took me awhile to
notice the pattern) which in Linux does just fine.  Frequently, after
manipulating an image on the Windows version, it crashes when I elect to save
it.  

Gotta get this wonderful program off of that KDE for windows.

Ok, then you are most likely experiencing problems due to the state of KDE and
digikam on Windows. Personally, I'm not a Windows developer.
Is there any problem that can be reproduced on Linux?

I've not spent much time on digiKam on Linux yet, but it indeed is a very
different animal, all to the better.  

I, too, had concluded that apparently the issues are due to the KDE in Windows.

All the more reason to divorce this wonderful program and let it run in Windows
w/o KDE.  

Are you familiar with XnView?  Apparently also by a Francophone!  It's great in
Windows and is also available in Linux, but not the Debian package.  For me, it
displaced Irfanview as my preferred photo program.  Now, it's a battle between
XnView and DigiKam.  The winner is decided by what I'm trying to do.

Paul,

Your digiKam version under windows is pretty old. I personnaly fixed some issue
under Windows.

I recommend to test with current implementation from svn (1.5.0)

Paul,

Can you please test with digikam 1.7.0 if these bugs are still there ?
There is a windows installer available here:
http://sourceforge.net/projects/digikam/files/digikam/1.7.0/digiKam-installer-1.7-win32.exe/download

Your  feedback is very appraciated because most developpers only use the linux
version...
