[Bug 204311] New: choice of resizing algorithms in resize dialog along with preview of each

https://bugs.kde.org/show_bug.cgi?id=204311

           Summary: choice of resizing algorithms in resize dialog along
                    with preview of each
           Product: showfoto
           Version: unspecified
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR
         Component: general
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:            (using KDE 4.3.0)
OS:                Linux
Installed from:    Gentoo Packages

Rescaling is one of the most common things done to an image, and the choice of
an appropriate algorithm makes a huge difference to the end result. Currently
there is no choice as to which rescaling algorithm showFoto should use. What I
would love to see, something that no other image editor I know of offers, is a
more advanced "resize" dialog. It would offer not only a choice of the (many
available) resizing algorithms, but it would also quickly compute a 100% crop
of a selected part of the image using each algorithm. Often I end up wasting
time trying out several different programs, including command line, in order to
find an algorithm that will not rape my image once I downscale it.

Don't think it makes a difference? See this:

Current 0.10.0 interface:

--- Comment #1 from DrSlony <[hidden email]> ---
Confirmed that the downscaling algorithm in digiKam-5.0.0 does a great job.
