ViewMode Property

Summary

Gets or sets the CodecsVectorViewMode that controls the actual size of the viewport when rasterizing vector image files.

Syntax

Objective-C

C++/CLI

Java

Python

public CodecsVectorViewMode ViewMode { get; set; }

@property (nonatomic, assign) LTCodecsVectorViewMode viewMode;

public CodecsVectorViewMode getViewMode() 
public void setViewMode(CodecsVectorViewMode viewMode)

public: 
property CodecsVectorViewMode ViewMode { 
   CodecsVectorViewMode get(); 
   void set (    CodecsVectorViewMode ); 
}

ViewMode # get and set (CodecsVectorLoadOptions)

Property Value

A CodecsVectorViewMode that controls the actual size of the viewport when rasterizing vector image files.

Remarks

A vector image file format usually does not have a physical size. The user can specify a viewport (physical size up to which the drawing can be rendered) ViewWidth and ViewHeight. How the drawing is to be rendered inside this viewport depends on the current viewport mode set with ViewMode. Default viewport size is 640x480 pixels.

Example

using Leadtools; 
using Leadtools.Codecs; 
 
using Leadtools.ImageProcessing.Core; 
 
public void CodecsVectorLoadOptionsExample() 
{ 
   RasterCodecs codecs = new RasterCodecs(); 
 
   string srcFileName = Path.Combine(LEAD_VARS.ImagesDir, "random.dxf"); 
 
   //Check if it is a vector file 
   CodecsImageInfo info = codecs.GetInformation(srcFileName, false); 
   Debug.WriteLine($"Is {srcFileName} a vector file? : {info.Vector.IsVectorFile}"); 
   Debug.WriteLine($"Units: {info.Vector.Unit}"); 
 
   //Parallelogram data 
   CodecsVectorImageInfo codecsVectorImageInfo = info.Vector; 
   Debug.WriteLine($"Parallelogram Max X: {codecsVectorImageInfo.ParallelogramMaxX}"); 
   Debug.WriteLine($"Parallelogram Max Y: {codecsVectorImageInfo.ParallelogramMaxY}"); 
   Debug.WriteLine($"Parallelogram Max Z: {codecsVectorImageInfo.ParallelogramMaxZ}"); 
   Debug.WriteLine($"Parallelogram Min X: {codecsVectorImageInfo.ParallelogramMinX}"); 
   Debug.WriteLine($"Parallelogram Min Y: {codecsVectorImageInfo.ParallelogramMinY}"); 
   Debug.WriteLine($"Parallelogram Min Z: {codecsVectorImageInfo.ParallelogramMinZ}"); 
 
   // Set the vector load options 
   // CodecsVectorOptions & CodecsVectorLoadOptions reference 
   codecs.Options.Vector.Load.BackgroundColor = new RasterColor(255, 255, 255); 
   codecs.Options.Vector.Load.BitsPerPixel = 24; 
   codecs.Options.Vector.Load.ForceBackgroundColor = true; 
   codecs.Options.Vector.Load.ViewWidth = 800; 
   codecs.Options.Vector.Load.ViewHeight = 800; 
   codecs.Options.Vector.Load.ViewMode = CodecsVectorViewMode.UseBest; 
 
   // Load the image 
   RasterImage image = codecs.Load(srcFileName); 
   // do something with the image here 
 
   // Clean up 
   image.Dispose(); 
   codecs.Dispose(); 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS22\Resources\Images";
