Take a look in the .NET interface help file for the documentation on the RasterDocumentEngine.SaveResultsToMemory method, it should have a simple example showing how to get the text of your OCR results as a string.

If you have any more questions or problems, make sure you let us know what LEDTOOLS version and interface (.NET, API, COM, etc.) you are using because I am assuming you are using v15 with .NET.

In the v15 .NET libraries, Invalid File Format means one of three things:

The file is actually invalid. If you can load the same file in one of our pre-compiled demos that ship with the toolkit, then this is not the case.

You did not call RasterCodecs.StartUp

You are not including as a reference or copying to your .exe's directory the necessary codecs dll for the file format. These dlls follow the naming convention of Leadtools.Codecs.???.dll (e.g. Leadtools.Codecs.Tif.dll). To learn which dlls are necessary for a particular file format, please read the help file article "Files to be Included With Your Application" and find the row for the file format in question.

If you have any more questions or problems, please let me know.
