[Mono-list] How can I copy one drawable into another?

[Ian Norton]

Hi Francisco,

If you have a png on disk, this is done like so:

void PaintImage( Context ctx, ImageSurface img, int x, int y ){
  img.Show( ctx, x, y );	
}
...
ImageSurface image = new ImageSurface( filename );
PaintImage( ctx, image, 10, 20 );

If you have a Gtk.Image and want to turn it into a Cairo ImageSurface
then you at the moment have to do something horrible like this:

Gtk.Image myImage;
...
Gdk.PixBuf buf = myImage.PixBuf;
buf.Save( "temp_convert","png" );
ImageSurface image = new ImageSurface ( "temp_convert" );

Regards

Ian
