Drawing.getSplineBezierControlPoints Method

Gets the control points needed for a Bézier line segment to display a cardinal spline connecting two points with the specified tension.

This method is static.

prevX: Type: Number - May be null
The X coordinate of the point preceding the start of the segment, or null if none.
prevY: Type: Number - May be null
The Y coordinate of the point preceding the start of the segment, or null if none.
startX: Type: Number
The X coordinate of the start of the segment.
startY: Type: Number
The Y coordinate of the start of the segment.
endX: Type: Number
The X coordinate of the end of the segment.
endY: Type: Number
The Y coordinate of the end of the segment.
nextX: Type: Number - May be null
The X coordinate of the point following the end of the segment, or null if none.
nextY: Type: Number - May be null
The Y coordinate of the point following the end of the segment, or null if none.
tension: Type: Number
The tension between 0 and 1 where 1 is a straight line segment and 0 forms a Catmull-Rom spline.
