Asynchronously determines whether a specified image, document or vector stream can be loaded as SVG.
public static Task<bool> CanLoadSvgAsync(
this RasterCodecs rasterCodecs,
ILeadStream stream
)
rasterCodecs
RasterCodecs object to perform the operation.
stream
The stream containing the image data to load.
A Task
that represents the asynchronous operation. TResult
: true if the specified image, document or vector file can be loaded as SVG, otherwise; false.
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.
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.
