示例1: InvalidateAnglePreview
private void InvalidateAnglePreview(IDiagramPresenter diagramPresenter) {
// invalidate previous angle preview
diagramPresenter.InvalidateDiagram(
rectBuffer.X - rectBuffer.Width - diagramPresenter.GripSize,
rectBuffer.Y - rectBuffer.Height - diagramPresenter.GripSize,
rectBuffer.Width + rectBuffer.Width + (2 * diagramPresenter.GripSize),
rectBuffer.Height + rectBuffer.Height + (2 * diagramPresenter.GripSize));
int requiredDistance;
diagramPresenter.ControlToDiagram(diagramPresenter.MinRotateRange, out requiredDistance);
int length = (int)Math.Round(Geometry.DistancePointPoint(ActionStartMouseState.X, ActionStartMouseState.Y, CurrentMouseState.X, CurrentMouseState.Y));
// invalidate current angle preview / instruction preview
rectBuffer.Location = ActionStartMouseState.Position;
if (length > requiredDistance)
rectBuffer.Width = rectBuffer.Height = length;
else
rectBuffer.Width = rectBuffer.Height = requiredDistance;
diagramPresenter.InvalidateDiagram(rectBuffer.X - rectBuffer.Width, rectBuffer.Y - rectBuffer.Height, rectBuffer.Width + rectBuffer.Width, rectBuffer.Height + rectBuffer.Height);
