BendCommand Constructor(int,LeadPoint,RasterColor,BendCommandFlags)

Summary

Initializes a new BendCommand class object with explicit parameters.

Syntax

C++/CLI

Python

public BendCommand( 
   int value, 
   LeadPoint centerPoint, 
   RasterColor fillColor, 
   BendCommandFlags flags 
)

public: 
BendCommand(  
   int value, 
   LeadPoint centerPoint, 
   RasterColor fillColor, 
   BendCommandFlags flags 
)

__init__(self,value,centerPoint,fillColor,flags) # Overloaded constructor

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.

Example

Run the BendCommand on an image.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.SpecialEffects; 
 
 
public void BendConstructorExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample5.cmp")); 
 
   // Prepare the command 
   BendCommand command = new BendCommand(); 
   command.Value = -250; 
   // bend the image around its center. 
   command.CenterPoint = new LeadPoint(image.Width / 2, image.Height / 2); 
   command.Flags = BendCommandFlags.Color | BendCommandFlags.WithoutRotate | BendCommandFlags.Normal; 
   command.FillColor = new RasterColor(255, 0, 0); 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS22\Resources\Images"; 
}
