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.

Remarks

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.
