Public Shared Function LoadFromStream( _
   ByVal stream As Stream, _
   ByVal options As SvgLoadOptions _
) As SvgDocument

'Usage

Dim stream As Stream
Dim options As SvgLoadOptions
Dim value As SvgDocument

public:
static SvgDocument^ LoadFromStream( 
   Stream^ stream,
   SvgLoadOptions^ options
)

Parameters

stream: The stream containing SVG data
options: Options to use during load. If this parameter is null, then a default SvgLoadOptions object will be used.

Return Value

The SvgDocument object this method creates.

To get and set information about a document's bounds and resolution, refer to SVG Size, Bounds and Flat.

This example will load a SVG file from a web stream and show its properties
