While using gotk3 I came across this problem of resizing images to fit the container. As @diamondburned explained gdk pixbufs are statically the same size as the original image. Then if I want different sizes I will have to resize it.
I began searching for resources and i found these incredible sources:

All of the following suggest using the Image object draw and expose-.... signal hook to resize the pixelbuf and set it as the image again.
