Resolution Property

Summary

Gets or sets the resolution to load.

Syntax

Objective-C

C++/CLI

Java

Python

public LeadSize Resolution { get; set; }

@property (nonatomic, assign) LeadSize resolution;

public LeadSize getResolution() 
public void setResolution(LeadSize value)

public: 
property LeadSize Resolution { 
   LeadSize get(); 
   void set (    LeadSize ); 
}

Resolution # get and set (CodecsJbigLoadOptions)

Property Value

The resolution to load. The default value is 0,0.

Remarks

Specify 0 for both dimensions to load the default resolution, the highest resolution layer corresponding to the image with its FULL DIMENSIONS.

Ex: If the file contains the image at the following dimensions: 800X600, 400X 300 and 200X150, then in the default case the codec will load the image at 800X600.

Specify either the desired width or desired height to load, and use 0 to get the default for the other dimension. The load procedure will determine the closest resolution layer, which best fits the user's request.

Ex: If the file contains the image at the following dimensions: 800X600, 400X 300 and 200X150 and the user requests an image with width equal to 780 for example, then LEADTOOLS will automatically know that the proper width is 800 and load the image at the (800X600) resolution.

Specify one of the exact sets of dimensions in the file.

Example

using Leadtools; 
using Leadtools.Codecs; 
 
using Leadtools.ImageProcessing.Core; 
 
public void CodecsJbigOptionsExample() 
{ 
   RasterCodecs codecs = new RasterCodecs(); 
 
   string srcFileName = Path.Combine(LEAD_VARS.ImagesDir, "ocr1.tif"); 
   RasterImage srcImage = codecs.Load(srcFileName); 
 
   // Ex: If the file contains the image  
   // at the following dimensions: 800X600,  
   // 400X 300 and 200X150 and the user requests  
   // an image with width equal to 180 for example,  
   // then LEADTOOLS will automatically know that the  
   // proper width is 200 and load the image at the (200X150) resolution.          
   codecs.Options.Jbig.Load.Resolution = new LeadSize(180, 0); // CodecsJbigOptions & CodecsJbigLoadOptions reference 
   LeadSize[] sizes = new LeadSize[3]; 
   sizes[0] = new LeadSize(800, 600); 
   sizes[1] = new LeadSize(400, 300); 
   sizes[2] = new LeadSize(200, 150); 
   codecs.Options.Save.SetResolutions(sizes); 
   codecs.Save(srcImage, Path.Combine(LEAD_VARS.ImagesDir, "Image1_test.jbg"), RasterImageFormat.Jbig, 8); 
   srcImage = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Image1_test.jbg")); 
 
   codecs.Save(srcImage, Path.Combine(LEAD_VARS.ImagesDir, "jbg.bmp"), RasterImageFormat.Bmp, 1); 
 
   // Clean up 
   srcImage.Dispose(); 
   codecs.Dispose(); 
}

{ 
   public const string ImagesDir = @"C:\LEADTOOLS22\Resources\Images";
