Description Dennis Nienhüser 2008-06-09 23:35:55 UTC

Version:            (using Devel)
Installed from:    Compiled sources

Right now a linear transformation is used to scale pictures which usually gives bad results. Qt allows smooth scaling, but this transformation is noticably more cpu intensive and therefore not always possible. The patch attached adds an option to use smooth scaling (can't check in directly due to message freeze).
