HOW TO: Minimize memory usage when OCR'ing large documents

This sample C# 2003 project uses our LEADTOOLS v14.5 .NET libraries to:

1. Minimze memory usage by loading and OCR'ing only one page at a time
2. Save all OCR'ed pages as a PDF

Here's a v15 C# 2005 version of the same demo

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.

The attached project is update that uses LEADTOOLS v17.5. This project built using C# in MS-VS2008.
The project uses the Advantage OCR engine.

The attached project is update that uses LEADTOOLS v18. This project is .NET 4 project that let you choose either Advantage or Professional engine.
