Computes the least-squares best fit plane for an image.

Syntax

public static void FindTilt( 
   ImGearRasterPage page,
   out double slopeX,
   out double slopeY,
   out double piston
)

public: static void FindTilt( 
   ImGearRasterPage* page,
   [PARAMFLAG::Out] double slopeX,
   [PARAMFLAG::Out] double slopeY,
   [PARAMFLAG::Out] double piston
)

public:
static void FindTilt( 
   ImGearRasterPage^ page,
   [Out] double slopeX,
   [Out] double slopeY,
   [Out] double piston
)

'Declaration
 
Public Shared Sub FindTilt( _
   ByVal page As ImGearRasterPage, _
   ByRef slopeX As Double, _
   ByRef slopeY As Double, _
   ByRef piston As Double _
)

'Usage
 
Dim page As ImGearRasterPage
Dim slopeX As Double
Dim slopeY As Double
Dim piston As Double
 
ImGearRasterProcessing.FindTilt(page, slopeX, slopeY, piston)

Parameters

page: An ImageGear.Core.ImGearRasterPage class object to process.
slopeX: Returns the slope in the X direction of the tilt plane.
slopeY: Returns the slope in the Y direction of the tilt plane.
piston: Returns the piston of the tilt plane.

Remarks

This method computes the least-squares best fit plane for an image. The plane will be given by formula:

f(x, y) = SlopeX * x + SlopeY * y + Piston.

Can be applied only to 8, 16 or 32bit grayscale images with one channel.

Example

C#
Visual Basic

// Find the tilt of an image.
double slopeX, slopeY, piston;
ImGearRasterProcessing.FindTilt(igRasterPage, out slopeX, out slopeY, out piston);

// Add the found tilt from the image, in effect removing it.
ImGearRasterProcessing.AddTilt(igRasterPage, slopeX, slopeY);

' Find the tilt of an image.
Dim slopeX As Double, slopeY As Double, piston As Double
ImGearRasterProcessing.FindTilt(igRasterPage, slopeX, slopeY, piston)

' Add the found tilt from the image, in effect removing it.
ImGearRasterProcessing.AddTilt(igRasterPage, slopeX, slopeY)
