GetCurvePoints Method

Updates the curve array based on a curve or lines that pass through the specified points.
public static int GetCurvePoints( 
   int[] curve, 
   LeadPoint[] userPoints, 
   CurvePointsType type 
Public Shared Function GetCurvePoints( _ 
   ByVal curve() As Integer, _ 
   ByVal userPoints() As LeadPoint, _ 
   ByVal type As CurvePointsType _ 
) As Integer 
+ (NSUInteger)getCurvePoints:(int *)curve 
                  userPoints:(const LeadPoint *)userPoints 
                       error:(NSError **)error 
public static int getCurvePoints( 
   int[] curve,  
   LeadPoint[] userPoints,  
   CurvePointsType type 
static int GetCurvePoints(  
   array<int>^ curve, 
   array<LeadPoint>^ userPoints, 
   CurvePointsType type 


Array of integers to be filled by this method. To get the real value of the array elements, each of the values must be divided by 1000.

Array of LeadPoint structures that contain the points on the curve used to determine the values of curve array. The minimum x coordinate value is 0.

Flag that indicates the method to be used to update the curve array.

Return Value

return the number of entries in curve array that were actually updated by this method.

  • This method will update curve array using either the best curve or lines that pass through the points specified in the userPoints array. The points in the array may be sorted or not. In most cases, this method is used with the FreeHandShearCommand, or FreeHandWaveCommand .
  • To compute the size of the curve array: Size = Maximum (userPoint.X) + userPoints.Length; This means that the user needs to find the maximum x coordinate value out of userPoint and add the number of Points (userPoints.Length) sent to the method.

  • It's recommended to initialize the array curve before sending it to the function.

  • The values stored in curve represent the y coordinates of the calculated curve based on the points in the userPoint array. In the curve array there can be only one y value for each x coordinate. Therefore, circles, ellipses, and spirals cannot be represented by curve.
  • The x coordinates for the user points are sorted internally automatically.

Refer to FreeHandShearCommand and FreeHandWaveCommandexamples.
