So those five lines become just two:
$pb = Gtk2::Gdk::Pixbuf->new('rgb', 0, 24, 10, 10);$pb->fill($color[0] << 24 | $color[1] << 16 | $color[2] << 8);
which seems to work in my normal environment. I can't just now test the Windows environment where the previous solution failed but I'm hopeful.
Hey, while I'm asking. I have another pixbuf question. I've been creating a canvas in C (simple malloced buffer), from which I've then made a gdk pixbuf with gdk_pixbuf_new_from_data. I have used on the canvas my own drawing routines. Now I'd like to use also Cairo besides my own. It should work somehow like this, I assume:
I malloc my canvasI create an image surface for data (my canvas)I create a context for this surfaceNow I can draw on this canvas with Cairo and with my own routinesI proceed as before with gdk_pixbuf_new_from_data
Should this work? My initial tests in Perl according these lines do not work.
Thanks,
Ari
