Remarks

This method might use the cache and will throw an exception if neither LoadDocumentOptions.Cache nor Cache was setup with a valid cache object if certain options are used.

Note that uri can point to a document stored in HTTP, HTTPS, FTP, or Disk file (using the file protocol).

LoadFromFile, LoadFromUri, LoadFromUriAsync and LoadFromStream creates a Document class from any supported image or document file format stored in a disk file, remote URL or stream. The returned object can then be used to retrieve any page as image or SVG, to obtain the text using SVG or OCR, use the annotations or the document structure such as links and bookmarks.

After the document is obtained, InternalObject will be to the internal LEADTOOLS object used with the document.
