override void EdgeClustering.GraphDrawer.OnRender

(

System.Windows.Media.DrawingContext

dc

)

[protected]

Draws everything.

Parameters:

dc

Definition at line 79 of file GraphDrawer.cs.

void EdgeClustering.GraphDrawer.DrawEnhancedGraph	(	DrawingContext	dc,
		Color	c,
		List< EnhancedEdge >	edges
	)			[private]

Draws the Cardinal Splines representing the edge clustered graph. For each edge the control points are sorted by the distance to the starting point. After that the Cardinal Splines are built using the endpoints and the sorted control points.

Parameters:

	dc
	c
	edges	enhanced edges with control point information

Definition at line 127 of file GraphDrawer.cs.

void EdgeClustering.GraphDrawer.DrawControlPoints	(	DrawingContext	dc,
		Color	c,
		List< EnhancedEdge >	edges
	)			[private]

Draws the control points.

Parameters:

	dc
	c	color
	edges	list of enhanced edges containing the control point information.

Definition at line 179 of file GraphDrawer.cs.

void EdgeClustering.GraphDrawer.DrawControlMesh	(	DrawingContext	dc,
		Color	c,
		List< ControlMeshEdge >	edges,
		List< ControlMeshVertex >	vertices
	)			[private]

Draws the Control Mesh with the given Color.

Parameters:

	dc
	c	color
	edges	list of Control Mesh edges
	vertices	list of Control Mesh vertices

Definition at line 198 of file GraphDrawer.cs.

void EdgeClustering.GraphDrawer.DrawMeshEdges	(	DrawingContext	dc,
		Color	c,
		List< SimpleEdge >	meshEdges
	)			[private]

Draws the control mesh edges computed for the mergedsegments.

Parameters:

	dc
	c

Definition at line 218 of file GraphDrawer.cs.

void EdgeClustering.GraphDrawer.DrawMergedSegments	(	DrawingContext	dc,
		List< MergedSegment >	mergedSegments,
		Color	color
	)			[private]

Draws the merged segments.

Parameters:

	dc
	mergedSegments	List of merged segments.

Definition at line 240 of file GraphDrawer.cs.

void EdgeClustering.GraphDrawer.DrawKernelPeak	(	DrawingContext	dc,
		Color	color,
		double	kernelPeaks[,]
	)			[private]

Draws the output of the kde computation.

Parameters:

	dc
	color

Parameters:

	dc	drawing context
	color	color
	grid	grid containing list of segment angles

Definition at line 309 of file GraphDrawer.cs.

void EdgeClustering.GraphDrawer.DrawAngle	(	DrawingContext	dc,
		Pen	pen,
		int	x,
		int	y,
		double	angle
	)			[private]
