 You could use the System.Drawing API as it has this functionality
 already.
 
 If you want to stick to gtk# and Pixbufs, you need to render the pixbuf
 into a pixmap which is the only object that you can use to render text
 with Pango.

This reminds me, gtk-sharp needs to wrap the pango_cairo_* functions
from pango 1.10 as soon as possible so that people don't need to
p/invoke when using pango with cairo surfaces (which has big advantages
over the pixmap method).

[Mono-list] How to draw a text string to existing photo (gtk#)

2006-03-25 Thread Slava Petrenko 
Hi all,

I'm looking for an approach to put some text string to existing jpeg
image. Now I can load a photo into Gdk.Pixbuf and I can create
Pango.Layout for a text string. So I have my image in a Gdk.Pixbuf and
my text string in a Pango.Layout, how can I put those things together to
obtain an image with text drawn on it? Any suggestions and sample codes
are welcome.

If you want to stick to gtk# and Pixbufs, you need to render the pixbuf
into a pixmap which is the only object that you can use to render text
with Pango.

Then you transform the pixmap back into a pixbuf and save that.
