public interface ISvgDocument : System.IDisposable, System.Runtime.Serialization.ISerializable

'Declaration

Public Interface ISvgDocument 
   Inherits System.IDisposable, System.Runtime.Serialization.ISerializable

'Usage

Dim instance As ISvgDocument

public interface ISvgDocument : IClosable //In WinRT the IDisposable interface is replaced by IClosable, ~Remove~

@protocol ISvgDocument <NSObject>

public interface ISvgDocument

function Leadtools.ISvgDocument() System.IDisposable, System.Runtime.Serialization.ISerializable

public interface class ISvgDocument : public System.IDisposable, System.Runtime.Serialization.ISerializable

The SvgDocument class implements ISvgDocument. You should always cast ISvgDocument to SvgDocument to access the actual properties/methods of the SVG document class.

The interface is used by the LEADTOOLS framework to minimize dependencies between the various assemblies. For example, the Leadtools.Codecs.RasterCodecs.LoadSvg method (define in Leadtools.Codecs.dll) returns Leadtools.ISvgDocument (defined in Leadtools.dll) instead of Leadtools.Svg.SvgDocument (defined in Leadtools.Svg.dll). This way, Leadtools.Codecs.dll does not have a dependency on Leadtools.Svg.dll if SVG functionality is not required by your application.
