AddOrthoPoints Method

In This Topic

This method is called by CalculateStroke when Orthogonal is true and both ports are instances of GoPort and at least one of them have a link spot that is not NoSpot.

Syntax

protected virtual void AddOrthoPoints( 
   PointF startFrom,
   float fromDir,
   PointF endTo,
   float toDir
)

Parameters

startFrom: this point will already have been added to the stroke by CalculateStroke before calling this method
fromDir: normally 0, 90, 180, or 270 degrees
endTo: CalculateStroke will add this point after calling this method
toDir: normally 0, 90, 180, or 270 degrees

Remarks

CalculateStroke is responsible for adding the first two and the last two points of the stroke, including and . This method is responsible for adding any additional points in the middle of the stroke. This method calls GetMidOrthoPosition to determine the distance of the middle segment between the two ports. It also tries to avoid the source node and the destination node. When the AvoidsNodes property is true, this method uses another, more computationally expensive, method for determining the proper path of the link, which may have many segments.
