示例1: Create
public override object Create(object img)
{
Gdk.Pixbuf pb = (Gdk.Pixbuf)img;
var imgs = new Cairo.ImageSurface (Cairo.Format.ARGB32, pb.Width, pb.Height);
var ic = new Cairo.Context (imgs);
Gdk.CairoHelper.SetSourcePixbuf (ic, pb, 0, 0);
ic.Paint ();
imgs.Flush ();
((IDisposable)ic).Dispose ();
var p = new Cairo.SurfacePattern (imgs);
p.Extend = Cairo.Extend.Repeat;
return p;
}示例2: GetPattern
public Cairo.Pattern GetPattern (ApplicationContext actx, double scaleFactor)
{
if (pattern == null || currentScaleFactor != scaleFactor) {
if (pattern != null)
pattern.Dispose ();
