CodecsVectorOptions Class

Summary

Provides support for loading or saving a vector image file.

Syntax

Objective-C

C++/CLI

Java

Python

public class CodecsVectorOptions

@interface LTCodecsVectorOptions : NSObject

public class CodecsVectorOptions

public ref class CodecsVectorOptions

class CodecsVectorOptions:

Remarks

LEADTOOLS provides support for loading a vector image as a raster image. Vector formats such as DXF, DWG and SVG can be converted to a raster image through a process called rasterization.

Example

Java

using Leadtools; 
using Leadtools.Codecs; 
 
using Leadtools.ImageProcessing.Core; 
using Leadtools.Pdf;

   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;
