Document Property

Summary

Gets the ISvgDocument object being loaded.

Syntax

C++/CLI

Java

Python

public ISvgDocument Document { get; }

public SvgDocument getDocument()

public: 
property ISvgDocument^ Document { 
   ISvgDocument^ get(); 
}

Document # get  (CodecsLoadSvgAsyncCompletedEventArgs)

Property Value

A ISvgDocument object that is being loaded, or a null reference if an error occurred.

Remarks

NOTE: This topic is part of RasterCodecs Async support using the .NET System.ComponentMode.AsyncOperation model. For .NET async/await support this type/member is not used. Instead, refer to RasterCodecs Async Operations.

When the asynchronous operation completes, the RasterCodecs.LoadSvgAsyncCompleted event will fire and Document will contain the final and ready to use object. If an error occurs, this property will be set to null and the object is disposed internally by the toolkit.

When an error occur, either the Error property is not a null reference or the Cancelled property is true.

Example

using Leadtools.ImageProcessing; 
using Leadtools.ImageProcessing.Color; 
using Leadtools.Svg;

   // Address of a document thats supports loading as SVG, for example, a DOCX file 
   string address = @"http://localhost/images/examples/leadtools.docx"; 
 
   EventHandler<CodecsLoadSvgAsyncCompletedEventArgs> loadSvgAsyncCompleted = null; 
 
   loadSvgAsyncCompleted = (sender, e) => 
   { 
      var thisCodecs = sender as RasterCodecs; 
      // Remove the handler 
      thisCodecs.LoadSvgAsyncCompleted -= loadSvgAsyncCompleted;

   codecs.LoadSvgAsyncCompleted += loadSvgAsyncCompleted;
