Hello,
The following code displays a blank stage (i.e. the image is not
rendered at all). Why is this so? I'd expect a 50x50 rectangle to be
visible.
import clutter
from clutter import cogl
class Texture(clutter.Texture):
__gtype_name__ = 'Texture'
def do_paint(self):
cogl.push_matrix()
cogl.clip_set(0, 0, 50, 50)
clutter.Texture.do_paint(self)
cogl.clip_unset()
cogl.pop_matrix()
stage = clutter.Stage()
stage.set_size(640, 480)
stage.connect('key-press-event', clutter.main_quit)
tex = Texture('image.png')
tex.set_size(200, 200)
stage.add(tex)
stage.show_all()
clutter.main()
Thomas
