ImageGear21.Processing.Advanced Assembly > ImageGear.Processing Namespace > ImGearEffects Class : Pinch Method

page: Page to pinch.

center: Center of the pinch effect.

radius: Radius of the pinch effect.

strength: Pinch strength. Positive value means that the page is pinched away from the center.

interpolate: If this parameter is true then an interpolation is used during processing.

color: Pixel color.

This method pinches a page toward or away from the pinch center.

'Declaration
 
Public Shared Sub Pinch( _
   ByVal page As ImGearRasterPage, _
   ByVal center As ImGearPoint, _
   ByVal radius As Integer, _
   ByVal strength As Single, _
   ByVal interpolate As Boolean, _
   ByVal color As ImGearPixel _
)

'Usage
 
Dim page As ImGearRasterPage
Dim center As ImGearPoint
Dim radius As Integer
Dim strength As Single
Dim interpolate As Boolean
Dim color As ImGearPixel
 
ImGearEffects.Pinch(page, center, radius, strength, interpolate, color)

public static void Pinch( 
   ImGearRasterPage page,
   ImGearPoint center,
   int radius,
   float strength,
   bool interpolate,
   ImGearPixel color
)

public: static void Pinch( 
   ImGearRasterPage* page,
   ImGearPoint center,
   int radius,
   float strength,
   bool interpolate,
   ImGearPixel* color
)

public:
static void Pinch( 
   ImGearRasterPage^ page,
   ImGearPoint center,
   int radius,
   float strength,
   bool interpolate,
   ImGearPixel^ color
)

Parameters

page: Page to pinch.
center: Center of the pinch effect.
radius: Radius of the pinch effect.
strength: Pinch strength. Positive value means that the page is pinched away from the center.
interpolate: If this parameter is true then an interpolation is used during processing.
color: Pixel color.
