Description Dik Takken 2008-06-03 22:04:01 UTC 
Version:           0.9.4-beta4 (using KDE 3.5.8)
OS:                Linux

Using the refocus plugin on large photographs consistently crashes DigiKam (SIGABRT), while some other plugins work just fine. Perhaps this plugin is trying to allocate a single, large chunk of memory, causing the program to fail...

It would be great if this plugin can be made to work well when used on very large files.

Dik,

Whitch size exactly ? 

Are you a backtrace of the scratch ?

Comment 2 Andi Clemens 2008-07-23 18:29:56 UTC 
This could be a CImg issue? Like Gilles said, can you provide a backtrace?
Comment 3 Andi Clemens 2008-07-23 18:32:24 UTC 
Oops refocus is not used with CImg... I thought of restoration plugin.. sorry!
Comment 4 caulier.gilles 2008-07-23 23:14:03 UTC 
Yes, it's not CImg. The memory consuming in refocusing is duing of a copy of image block around the whole image (i think). Look refocusing dialog implementation for details.

I can't get a sane backtrace unfortunately. I use DigiKam to work on 50 megapixel 16-bit photographs, scanned from 6x6 cm slides.

Is this report still valid? If so, can you upload an example image somewhere?

I cannot reproduce this problem, I guess it's been fixed.
