Remarks

This method will load the options saved to an XML file using the SaveOptions(string) method.

To load and save the options to an XML stream instead of a file, use LoadOptions(Stream) and SaveOptions(Stream).

Saving the options to an XML file allows you to set the options the required way once and then re-use them in multiple sessions (or multiple DocumentWriter instances). Each document format supported by the LEADTOOLS Document Writer contain extra functionality and options that can be accessed with the GetOptions and SetOptions methods. For more information, refer to DocumentOptions.

The following options are saved to the XML:
