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

Parameters

curve
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.
userPoints
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.
type
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.

Example

Remarks

  • 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 Leadtools.ImageProcessing.SpecialEffects.FreeHandShearCommand, or Leadtools.ImageProcessing.SpecialEffects.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.

Requirements

Target Platforms: Silverlight 3.0, Windows XP, Windows Server 2003 family, Windows Server 2008 family, Windows Vista, Windows 7, MAC OS/X (Intel Only)
