) As ImGearDocument

'Usage

Dim count As Integer
Dim value As ImGearDocument

public static ImGearDocument LoadDocument(

)

public: static ImGearDocument* LoadDocument( 
   Stream* stream,
   int startPageNumber,
   int count
)

public:
static ImGearDocument^ LoadDocument( 
   Stream^ stream,
   int startPageNumber,
   int count
)

Parameters

stream: The data stream containing an image.
startPageNumber: The number of the first page to load.
count: Total number of pages to load.

Return Value

A new instance of ImageGear.Core.ImGearDocument class.

This method allows you to load several pages in a single call and get access to the document level metadata of an image. It is recommended to use this method when working with PDF format since pages inside a PDF file depend on each other, and thus, loading them at once (as a document) is preferable to loading pages individually. If the format of an image cannot be detected, an exception is thrown. If the document size is close to 2GB, an exception of System.OutOfMemoryException will be thrown.
