To load the options saved into a disk file by the SaveOptions(string) method, use LoadOptions(string).
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 the options to be set the required way once and then re-used 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:
