Question

In GTK, how can I scale an image? Right now I load images with PIL and scale them beforehand, but is there a way to do it with GTK?

Answer 1

Load the image from a file using gtk.gdk.Pixbuf for that:

import gtk
pixbuf = gtk.gdk.pixbuf_new_from_file('/path/to/the/image.png')

then scale it:

pixbuf = pixbuf.scale_simple(width, height, gtk.gdk.INTERP_BILINEAR)

Then, if you want use it in a gtk.Image, crate the widget and set the image from the pixbuf.

image = gtk.Image()
image.set_from_pixbuf(pixbuf)

Or maybe in a direct way:

image = gtk.image_new_from_pixbuf(pixbuf)
