How to create PixBuf from a file using Gdk3?

Question

Wednesday: Python3

Libraries:

from gi.repository import Gtk, Gdk import cairo 

I want to create "pixbuf from a file", but this method no longer exists in Gdk3.

 pb = Gdk.pixbuf_new_from_file('sunshine.png') Gdk.cairo_set_source_pixbuf(cr, pb, 0, 0) 

Result in: AttributeError: object 'gi.repository.Gdk' does not have attribute 'pixbuf_new_from_file'

Does anyone know how to do this with Gdk3? Gdk3 seems to support only these methods:

 gdk_pixbuf_get_from_window gdk_pixbuf_get_from_surface 

Update

Found myself:

 image = Gtk.Image() image.set_from_file('sunshine.png') pixbuf = image.get_pixbuf() Gdk.cairo_set_source_pixbuf(cr, pixbuf, 10, 10) 

Answer 1

The question is old, but maybe it helps someone:

 from gi.repository import GdkPixbuf pixbuf = GdkPixbuf.Pixbuf.new_from_file('sunshine.png') 

Tested on GdkPixbuf._version == '2.0'

Answer 2

I don't know much about python, but in general, you should not use a gtk image directly to upload a file. Use GdkPixbuf instead because of error handling. The reason is that there is no (in python) attribute “pixbuf new from file”, because for most of the processing, GdkPixbuf is still used (in C) gdk-pixbuf-2.0. Why they do not spoil or still hold it, I have no idea. In python, you need to find the gdk pixbuf module instead of using GDK3, as Skriere noted.
