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

                                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.

Remarks

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

{ 
   // Assume the SVG file is located here 
   string srcFileName = Path.Combine(ImagesPath.Path, "Page1.svg"); 
 
   // Load the file into memory 
   byte[] data = File.ReadAllBytes(srcFileName); 
 
   // Load the SVG 
   using (SvgDocument document = SvgDocument.LoadFromMemory(data, 0, data.Length, null))
