Path to the URL containing the original document data. This value cannot be null.

options

Options to use when loading the document. This value cannot be null.

Return Value

The newly created document object.

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 LEADDocument 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.

Refer to Loading Using LEADTOOLS Document Library for detailed information on how to use this method and the various options used.
