           Summary: Plugin cannot be used on large photographs
           Product: digikamimageplugins
           Version: unspecified
          Platform: unspecified
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: NOR
         Component: Refocus
        AssignedTo: digikam-devel kde org
        ReportedBy: d.h.j.takken xs4all nl


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.

This could be a CImg issue? Like Gilles said, can you provide a backtrace?

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.
