ResizeRegionCommand Constructor(int,ResizeRegionCommandType,bool)

Summary

Initializes a new ResizeRegionCommand class object with explicit parameters.

Syntax

C++/CLI

Python

public ResizeRegionCommand( 
   int dimension, 
   ResizeRegionCommandType type, 
   bool asFrame 
)

public: 
ResizeRegionCommand(  
   int dimension, 
   ResizeRegionCommandType type, 
   bool asFrame 
)

__init__(self,dimension,type,asFrame) # Overloaded constructor

Parameters

dimension
Number of pixels by which to resize the region. This parameter only accepts positive values.

type
Value that indicates whether to contract or expand the image region.

asFrame
Value that indicates whether to create a frame associated with the resized image region. If this parameter is true, then the command creates a frame of thickness "dimension" for the resized region. If the type parameter is ResizeRegionCommandType.ExpandRegion, the frame created will exist outside the boundaries of the resized region. If the type parameter is ResizeRegionCommandType.ContractRegion, the frame will be within the boundaries of the resized region. If this parameter is false then the command resizes the region only, and does not create a frame.

Example

Run the ResizeRegionCommand on an image.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Effects; 
 
 
public void ResizeRegionConstructorExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "IMAGE1.CMP")); 
 
   // Prepare the command 
   //Rectangle that defines the region . 
   LeadRect rRgnRect = new LeadRect(80, 20, 100, 40); 
   //Create an elliptical region. 
   image.AddEllipseToRegion(null, rRgnRect, RasterRegionCombineMode.Set); 
   ResizeRegionCommand command = new ResizeRegionCommand(20, ResizeRegionCommandType.ContractRegion, true); 
   //Contract the image region by 20 pixels. 
   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:\LEADTOOLS23\Resources\Images"; 
}
