BendCommand Constructor(Int32,LeadPoint,RasterColor,BendCommandFlags)

Leadtools.ImageProcessing.SpecialEffects Namespace > BendCommand Class > BendCommand Constructor : BendCommand Constructor(Int32,LeadPoint,RasterColor,BendCommandFlags)



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.
Initializes a new BendCommand class object with explicit parameters.

Parameters

value

Example

Run the BendCommand on an image.

Public Sub BendConstructorExample()
   Dim codecs As New RasterCodecs()

   Dim leadImage As RasterImage = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Master.jpg"))

   ' Prepare the command
   Dim command As BendCommand = New BendCommand

   ' bend the Image around it is center.
   command.CenterPoint = New LeadPoint(CType((leadImage.Width / 2), Integer), CType((leadImage.Height / 2), Integer))
