I've got the following setup in my program:
def update_image(self):
mainwindow=self.widget_by_name("mainwindow")
canvas=self.widget_by_name("canvas")
mycopy=gtk.gdk.Pixmap(mainwindow.window,
self.image.pixbuf.get_width(),
self.image.pixbuf.get_height(),
-1)
self.image.pixbuf.render_to_drawable(mycopy,
canvas.get_style().fg_gc[0],
0,0,
0,0,
self.image.pixbuf.get_width(),
self.image.pixbuf.get_height(),
gtk.gdk.RGB_DITHER_NONE,
0,0)
mygc=gtk.gdk.gc_new(mycopy)
mycolor=gtk.gdk.color_parse("red")
print mycolor.red,mycolor.green,mycolor.blue
mygc.set_foreground(mycolor)
mygc.set_function(gtk.gdk.COPY)
for i in xrange(400):
mycopy.draw_point(mygc,i,i)
canvas.set_from_pixmap(mycopy,None)
Now my image shows a blue (not red). Actually the line drawn is always blue,
no matter what color I try to render.
mycolor seems to be correct, at least the print statement shows the correct
values.
Any ideas?
Andreas
