Parameters

fileName

A String containing the name of the image file to load.

pageNumber

The 1-based page number.

options

The options used for loading SVG. This can be null.

userState

A user-defined object that is passed to the method invoked when the asynchronous operation completes.

Use this method to load a page from any supported image, document or vector file as SVG (Scalable Vector Graphics). For more information refer LoadSvg(string fileName, int pageNumber, CodecsLoadSvgOptionsoptions).

The RasterCodecs class supports loading image data as SVG asynchronously using the LoadSvgAsync methods. When calling any of these methods, the caller thread will not be blocked and the method will return instantly. When the RasterCodecs object finishes loading the SVG page (or when an error occur), the LoadSvgAsyncCompleted will occur.

The LoadSvgAsyncCompleted event data will contain the SVG page in the CodecsLoadSvgAsyncCompletedEventArgs property.

To determine whether a file or stream can be loaded as SVG, use CanLoadSvg(string fileName) or CanLoadSvg(Stream stream).

To load as SVG asynchronously from a stream, use LoadSvgAsync(Stream stream, int pageNumber, CodecsLoadSvgOptions options, object userState).

To load as SVG asynchronously from a URI, use LoadSvgAsync(Uri uri, int pageNumber, CodecsLoadSvgOptions options, object userState).

To load as SVG from a file or stream directly, use LoadSvg.

For more information, refer to Working With SVG.

For an example, refer to LoadSvgAsyncCompleted.
