Version: 0.9.2-final (using KDE 3.5.7, Kubuntu (gutsy) 4:3.5.7-1ubuntu13) Compiler: Target: x86_64-linux-gnu OS: Linux (x86_64) release 2.6.20-16-generic When I scale images down, I generally expect the noise to get smaller, but it appears that the scaling algorithm digikam uses (Editor -> Transform -> Resize) does not bin pixels together, resulting in the same level of noise, and in some cases aliasing.
If you want to say that digikam does not perform anti-alias filtering during rescaling (scalig down) then I have to confirm this bug. The resize dialog was changed in order to add CIMG-support. Since then, the filtering is not working any more. IMHO it would be nice to let the user choose which filtering algorithm he prefers (bicubic, sinc,...). Instead, the user sees LOTS and LOTS of mystic parameters in the CIMG dialog... not nice. Just my $0.02 Florian
Hi again, I think that this is a regression since 0.9.2 and should not be treated as a WISH. Before introducing CIMG, this was working very well :-) Regards, Florian
Florian, This is not a regression. If you don't use the Cimg filter, the algorithm to resize an image is exactly the same than before (0.9.0, 0.9.1) ! Gilles
This bug is surely related to (if not the same) http://bugs.kde.org/show_bug.cgi?id=152192 .
Luke, Florian, http://bugs.kde.org/show_bug.cgi?id=152192 has been solved now. Could you please check if this bug can be closed as well? Thanks a lot in advance, Arnd
Hi Arnd, thank you for the link, it describes exactly what I wanted to communicate. IMHO you can close this bug here :-) Greetings, Florian
Florian, thanks a lot for the feedback! Closing this bug as FIXED.
