CanLoadSvgAsync Method

Summary

Asynchronously determines whether an specified image, document or vector stream can be loaded as SVG.

Syntax
C#
public static Task<bool> CanLoadSvgAsync( 
   this RasterCodecs rasterCodecs, 
   ILeadStream stream 
) 

Parameters

rasterCodecs

RasterCodecs object to perform the operation.

stream

The stream containing the image data to load.

Return Value

A Task that represents the asynchronous operation. TResult: true if the specified image, document or vector file can be loaded as SVG, otherwise; false.

Remarks

This topic is part of RasterCodecs support for .NET async/await support. Refer to RasterCodecs Async Operations for more information.

Use this method to determine if the specified image, document or vector file supports loading as SVG (Scalable Vector Graphics). The following conditions must be met to load a page from a file as SVG:

Condition Description
The file format is SVG

SVG can be loaded as SVG

The file format is document

Any of the document file formats supported by LEADTOOLS such DOCX/DOC, PPTX/PPT, XLSX/XLS, RTF, TXT, AFP, ICA, etc. These formats will set the CodecsDocumentImageInfo.IsDocumentFile property to true when calling GetInformationAsync

The file format is vector

Any of the vector file formats supported by LEADTOOLS such as DXF, DWG, etc. These formats will set the CodecsVectorImageInfo.IsVectorFile property to true when calling GetInformationAsync

The file format is PDF

And the PDF file contains more than pure raster data (for example, not scanned PDF file).

In addition to the usual format filter assembly (Leadtools.Codecs.*), The following additional assemblies may be required to support loading as SVG

Assembly Description
Leadtools.Svg

SVG support. Always required

Leadtools.Vector

Required if the input document is a vector file

Leadtools.Pdf

Required if the input document is a PDF file

To load a page as SVG from a file or stream, use LoadSvgAsync.

For more information, refer to Working With SVG.

Requirements

For .NET Framework: A reference to the Leadtools.Async.dll assembly is required to use this functionality.

For .NET Standard: This functionality is included in the Leadtools.Codecs.dll assembly.
