LEADTOOLS Image Processing (Leadtools.ImageProcessing.SpecialEffects assembly)
LEAD Technologies, Inc

BendCommand Constructor(Int32,LeadPoint,RasterColor,BendCommandFlags)

Example 





Amount of stretching, where positive values stretch the pixels toward the edges, and negative values stretch the pixels toward the center. Possible values are range in between -500 and 500.
Contains the center of the arc. This is ignored when either BendCommandFlags.Horizontal or BendCommandFlags.Vertical is set in the flags parameter.
Specifies the fill color for any exposed areas.
Flags that indicate how to handle peripherally exposed areas, how to handle centrally exposed areas and the type of bending. You can use a bitwise OR (|) to specify one flag from each group.
Initializes a new BendCommand class object with explicit parameters. .NET support WinRT support

Parameters

value
Amount of stretching, where positive values stretch the pixels toward the edges, and negative values stretch the pixels toward the center. Possible values are range in between -500 and 500.
centerPoint
Contains the center of the arc. This is ignored when either BendCommandFlags.Horizontal or BendCommandFlags.Vertical is set in the flags parameter.
fillColor
Specifies the fill color for any exposed areas.
flags
Flags that indicate how to handle peripherally exposed areas, how to handle centrally exposed areas and the type of bending. You can use a bitwise OR (|) to specify one flag from each group.

   ' bend the Image around it is center.
   command.CenterPoint = New LeadPoint(CType((leadImage.Width / 2), Integer), CType((leadImage.Height / 2), Integer))
   command.Flags = BendCommandFlags.Color Or BendCommandFlags.WithoutRotate Or BendCommandFlags.Normal
   command.FillColor = New RasterColor(255, 0, 0)
