示例1: GeometryHitTestParameters
/// <summary>
/// The constructor takes the geometry to hit test with.
/// </summary>
public GeometryHitTestParameters(Geometry geometry) : base()
{
// This ctor guarantees that we are initialized in the following way:
//
// 1. The geometry provided by the user is unmodified
// 2. _hitGeometryInternal is a PathGeometry equivilent to the supplied geometry
// 3. _hitGeometryInternal.Tranform is a MatrixTransform equivilent to the supplied
// geometry.Transform
// 4. _origBounds is the untransformed bounds of the _hitGeometryInternal (inner space).
// 5. _bounds is the transformed bounds of the _hitGeometryInternal (outer space).
// 6. _matrixStack is an empty stack.
if (geometry == null)
{
throw new ArgumentNullException("geometry");
}
// Convert the Geometry to an equivilent PathGeometry up front to prevent
// conversion on every call to DoesContainWithDetail. If the geometry is
// animate this also has the side effect of eliminating animation interplay.
_hitGeometryInternal = geometry.GetAsPathGeometry();
// If GetAsPathGeometry was a no-op, force the copy because we do not
// went to modify the user's Geometry.
if (object.ReferenceEquals(_hitGeometryInternal, geometry))
{
_hitGeometryInternal = _hitGeometryInternal.Clone();
}
// Convert _hitGeometryInternal.Transform to an equivilent MatrixTransform
// so that we can aggregate in PushMatrix/PopMatrix without building a
// TransformCollection.
Transform origTransform = _hitGeometryInternal.Transform;
MatrixTransform newTransform = new MatrixTransform();
_hitGeometryInternal.Transform = newTransform;
// Before we initialize MatrixTransform.Matrix, cache the bounds of this
// geometry without any transforms.
_origBounds = _hitGeometryInternal.Bounds;
// If we had a non-Identity transform, update our MatrixTransform.Matrix
// with its Value. (Note that when GetAsPathGeometry *isn't* a no-op
// it applies the transform to the figures and returns with a Geometry
// with an identity Transform.)
if (origTransform != null && !origTransform.IsIdentity)
{
newTransform.Matrix = origTransform.Value;
}
// Initialize the current transformed bounds of this Geometry
_bounds = _hitGeometryInternal.Bounds;
_matrixStack = new MatrixStack();
