In 16.0, we changed the design of the OCR engine and it no longer had this ability.

In 16.5, we fixed this problem.  We now have a DocumentWriter class that we use to save our own formats rather than the OCR engine's output formats.  This also gives us the ability to write to a "LEADTOOLS Temporary Document" format.  If you save on top of this kind of file, we will automatically append to it.  Then when you can use DocumentWriter.Convert to convert the LTD file to any of our supported Document Writer formats such as Doc, Txt, Pdf, etc.

Attached is a C# 2005 example that shows how to do this.
