ImGearEffects.WarpParabolic(page, center, strength, radiusX, radiusY, interpolate, color)

public static void WarpParabolic( 
   ImGearRasterPage page,
   ImGearPoint center,
   float strength,
   int radiusX,
   int radiusY,
   bool interpolate,
   ImGearPixel color
)

public: static void WarpParabolic( 
   ImGearRasterPage* page,
   ImGearPoint center,
   float strength,
   int radiusX,
   int radiusY,
   bool interpolate,
   ImGearPixel* color
)

public:
static void WarpParabolic( 
   ImGearRasterPage^ page,
   ImGearPoint center,
   float strength,
   int radiusX,
   int radiusY,
   bool interpolate,
   ImGearPixel^ color
)

Parameters

page: Page class object.
center: Center of the paraboloid in pixels.
strength: Extrusion strength.
radiusX: Length of the effect in X direction in pixels.
radiusY: Length of the effect in Y direction in pixels.
interpolate: If this parameter is true then an interpolation is used during processing.
color: ImageGear.Core.ImGearPixel class color.

Example

C#
Visual Basic

// Warp the image around a parabola.

// Center point of the parabola, set to center of image.
ImGearPoint igPoint = new ImGearPoint();
igPoint.X = igRasterPage.DIB.Width / 2;
igPoint.Y = igRasterPage.DIB.Height / 2;

// Warp around the parabola with a strength of 50000, an x radius of 300, a y radius of 100, 
//  interpolation on, and no fill color.
ImGearEffects.WarpParabolic(igRasterPage, igPoint, 50000, 300, 100, true, null);

' Warp the image around a parabola.

' Center point of the parabola, set to center of image.
Dim igPoint As New ImGearPoint()
igPoint.X = igRasterPage.DIB.Width / 2
igPoint.Y = igRasterPage.DIB.Height / 2

' Warp around the parabola with a strength of 50000, an x radius of 300, a y radius of 100, 
'  interpolation on, and no fill color.
ImGearEffects.WarpParabolic(igRasterPage, igPoint, 50000, 300, 100, True, Nothing)
