Description Andrew McNabb 2010-07-08 06:38:47 UTC 
Version:           1.2.0 (using KDE 4.4.4) 
OS:                Linux

I upgraded to Fedora 13 and tried to load my pictures directory into digikam.  My system has 2 GB of RAM, and Digikam used quite a bit of memory when importing the images.  When it got to a subdirectory with a large image (a 16384x8192 pixel TIFF), the memory usage went even higher, and the system nearly froze due to swap thrashing until I killed Digikam.  I then moved out the subdirectory with the large image and restarted Digikam, and this time it loaded without hanging.

Reproducible: Always

Did you try to edit/view the image, or do you refer to the initial scan when digikam sees the picture for the first time?

In the first case: Yes, an 8bit image of this size will use 512 MB of memory. Dont expect that to change in the near future.
In the latter case: Then I assume this has been fixed in libexiv2, which used to allocate lots of memory for large TIFFs in older versions.
Comment 3 Andrew McNabb 2011-01-18 17:43:41 UTC 
This problem occurred during the initial scan.  I have not recently retested this problem, but I'll try to get to it soon.
Comment 4 caulier.gilles 2011-07-06 10:54:26 UTC 
We need feedback using a recent version. 2.0.0 RC is out, please test...

Thanks in advance

With digiKam 5.0.0, this problem is not reproducible.
I close this file now. Don't hesitate to re-open if necessary.
