CodecsLoadSvgAsyncCompletedEventArgs Constructor

Summary

Creates new instance of the CodecsLoadSvgAsyncCompletedEventArgs with the specified parameters.

Syntax

C++/CLI

Python

public CodecsLoadSvgAsyncCompletedEventArgs( 
   ISvgDocument document, 
   Uri uri, 
   Stream stream, 
   string fileName, 
   Exception error, 
   bool cancelled, 
   object userState 
)

public: 
CodecsLoadSvgAsyncCompletedEventArgs(  
   ISvgDocument^ document, 
   Uri^ uri, 
   Stream^ stream, 
   String^ fileName, 
   Exception^ error, 
   bool cancelled, 
   Object^ userState 
)

__init__(self,document,uri,stream,fileName,error,cancelled,userState) # Overloaded constructor

Parameters

document
The ISvgDocument object instance being used.

uri
The Uri this asynchronous operation is using.

stream
The Stream this asynchronous operation is using.

fileName
The file name this asynchronous operation is using.

error
Any error that occurred during the asynchronous operation.

cancelled
A value indicating whether the asynchronous operation was canceled.

userState
The optional user-supplied state object passed to the RasterCodecs.LoadSvgAsync method that initialized the construction of this object.

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.
