Cut out pictures

[SamFaye]

I want to create an editor that allows me to cut picture as to what is done with GIMP.
But I wonder if there are no tools written in Qt / C + + that already exist.

If there are not a tool written in Qt/C++, is somebody know how can I cut out an image? I want to selection an part an copy or cut this part an create an image with it.

How can I do this?

I use the copy() method of QPixmap, but the copy is shifted. I mean that the selected part is not copied exactly, but it shifts to the right a few pixels and copy from there.

Can you produce a small example showing this?

If this is the case, then it shold file a bug report on JIRA.
