Version: (using KDE 4.0.98) Installed from: Compiled From Sources Compiler: gcc4.2.2 OS: Linux When you have to make significant perspective correction ability to only make image slower is problem. When I have to make correction of even 20% of image width only compressing this size significantly lowers quality of image. If I could eg. expand 10% upper part of image and compact 10% lower part of image losses wouldn't be that bad. At the moment image fills full space of plugin area. I suggest adding some arbitrary free space around which can be used to drag nodes into it when necessary. It doesn't have to be very big - 10-15% of image width/height should be enough.
Reported already (bug #167314).
