public static SvgDocument LoadFromMemory( 
   byte[] buffer,
   int offset,
   int length,
   SvgLoadOptions options
)

'Declaration

Public Shared Function LoadFromMemory( _
   ByVal buffer() As Byte, _
   ByVal offset As Integer, _
   ByVal length As Integer, _
   ByVal options As SvgLoadOptions _
) As SvgDocument

'Usage

Dim buffer() As Byte
Dim offset As Integer
Dim length As Integer
Dim options As SvgLoadOptions
Dim value As SvgDocument
 
value = SvgDocument.LoadFromMemory(buffer, offset, length, options)

                              options:(nullable LTSvgLoadOptions *)options
                                error:(NSError **)error

public static SvgDocument loadFromMemory(byte[] buffer, int offset, int length, SvgLoadOptions options)

public:
static SvgDocument^ LoadFromMemory( 
   array<byte>^ buffer,
   int offset,
   int length,
   SvgLoadOptions^ options
)

Parameters

buffer: Buffer containing the SVG data.
offset: 0-based offset into the buffer where the data begins.
length: Number of bytes to read.
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 the document's bounds and resolution, refer to SVG Size, Bounds and Flat.
