Summary
Determines whether specified image, document or vector stream can be loaded as SVG.
Syntax
public bool CanLoadSvg(Stream stream)
Public Overloads Function CanLoadSvg( _ByVal stream As Stream _) As Boolean
public bool CanLoadSvg(Stream stream)
- (BOOL)canLoadSvgStream:(LTLeadStream *)svgStream error:(NSError **)error public boolean canLoadSvg(ILeadStream stream) function Leadtools.Codecs.RasterCodecs.CanLoadSvg(Stream)(stream)
public:bool CanLoadSvg(Stream^ stream)
Parameters
stream
The input stream.
Return Value
true if the specified image, document or vector file can be loaded as SVG, otherwise; false.
Remarks
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 GetInformation |
| 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 GetInformation |
| 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 determine whether a file can be loaded as SVG, use CanLoadSvg(string fileName).
To load a page as SVG from a file or stream, use LoadSvg(string fileName, int pageNumber, CodecsLoadSvgOptions options) or LoadSvg(Stream stream, int pageNumber, CodecsLoadSvgOptions options).
To load as SVG asynchronously, use LoadSvgAsync.
For more information, refer to Working With SVG.
Example
For an example, refer to LoadSvg(string fileName, int pageNumber, CodecsLoadSvgOptions options).
