示例1:OnMouseMove
protectedoverridevoidOnMouseMove(objecto,Gtk.MotionNotifyEventArgsargs,Cairo.PointDpoint)
{
if(!is_drawing)
return;
doublex=Utility.Clamp(point.X,0,PintaCore.Workspace.ImageSize.X-1);
doubley=Utility.Clamp(point.Y,0,PintaCore.Workspace.ImageSize.Y-1);
PintaCore.Layers.ShowSelection=true;
ImageSurfacesurf=PintaCore.Layers.ToolLayer.Surface;
using(Contextg=newContext(surf)){
g.Antialias=Antialias.Subpixel;
if(path!=null){
g.AppendPath(path);
(pathasIDisposable).Dispose();
}
g.LineTo(x,y);
path=g.CopyPath();
g.FillRule=FillRule.EvenOdd;
g.ClosePath();
Pathold=PintaCore.Layers.SelectionPath;
PintaCore.Layers.SelectionPath=g.CopyPath();
(oldasIDisposable).Dispose();
}
PintaCore.Workspace.Invalidate();
}
