[Gambas-user] Need help with resizing Picutre contained by a resizable scrollview

[B. Jack]

It's off by more than a few border pixels.  The code tends to end up with something around double the area than the actual image (so an image always scrolls quite a bit even if it should fit in the window) but it's not exactly double and the difference changes if I load the project on different machines running the IDE (I'm thinking different X Windows DPI settings or something is going on and changing the units).
