示例1:
// Enumerator that specifies the drawing mode of the stroke.
public enum DrawingMode
{
Solid,
StyulusPoints
}示例2: if
private DrawingMode strokeMode = DrawingMode.Solid;
// Property that specifies whether to draw a solid stroke or the stylus points
public DrawingMode Mode
{
get
{
return strokeMode;
}
set
{
if (strokeMode != value)
{
strokeMode = value;
this.OnInvalidated(new EventArgs());
}
}
}
protected override void DrawCore(System.Windows.Media.DrawingContext context, DrawingAttributes overrides)
{
SolidColorBrush strokeBrush = new SolidColorBrush(overrides.Color);
// If strokeMode it set to Solid, draw the strokes regularly.
// Otherwise, draw the stylus points.
if (strokeMode == DrawingMode.Solid)
{
Geometry geometry = GetGeometry(overrides);
context.DrawGeometry(strokeBrush, null, geometry);
}
else // strokeMode == DrawingMode.StylusPoints
{
StylusPointCollection points;
// Get the stylus points used to draw the stroke. The points used depends on
// the value of FitToCurve.
if (this.DrawingAttributes.FitToCurve)
{
points = this.GetBezierStylusPoints();
}
else
{
points = this.StylusPoints;
}
// Draw a circle at each stylus point.
foreach (StylusPoint p in points)
{
context.DrawEllipse(null, new Pen(strokeBrush, 1), (Point)p, 5, 5);
}
}
