Vector Property

Summary

Gets extra information about the image if the file is a vector format.

Syntax

Objective-C

C++/CLI

Java

Python

public CodecsVectorImageInfo Vector { get; }

@property (nonatomic, strong, readonly) LTCodecsVectorImageInfo *vector;

public CodecsVectorImageInfo getVector()

public: 
property CodecsVectorImageInfo^ Vector { 
   CodecsVectorImageInfo^ get(); 
}

Vector # get  (CodecsImageInfo)

Property Value

A CodecsVectorImageInfo object containing the vector format information such as its logical size.

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.

Rasterization is the process of converting a vector image to a raster image. To determine whether a certain file on disk (or in a .NET stream) contains a vector image file rather than a regular raster image, call the RasterCodecs.GetInformation or RasterCodecs.GetInformationAsync method and check the CodecsVectorImageInfo.IsVectorFile property.

Example

Java

using Leadtools.ImageProcessing.Core;

   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}");
