Thanks for clarifying. Actually, I have to use Pango independently of a higher level library like GTK. Does pango-with-cairo support opentype fonts? <div class="gmail_quote">On Fri, Jun 26, 2009 at 5:12 PM, M Joonas Pihlaja <<a href="mailto:jpihlaja@cc.helsinki.fi">jpihlaja@cc.helsinki.fi</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"><div class="im">On Fri, 26 Jun 2009, Rabia Sirhindi wrote: > I am working on pango and using cairo as a rendering backend.

An image surface represents an array of pixels in memory only and it is never displayed by cairo onto a screen or window. You probably want a platform specific surface such as an xlib surface or something similar. For example, GDK has a gdk_cairo_create() function to create a cairo context for a window. Alternately, you could use cairo_surface_write_to_png() at the end of your code and use an image viewer to display the rendered results. Cheers, Joonas </blockquote></div> -- Regards, Rabia
