Which LEADTOOLS version (14, 15, 16, etc.) and programming interface (Main OCX, .NET classes, DLL API, C++ Classes, etc.) are you using?

If you are using .NET, you can save the zones to a stream using IOcrPage.SaveZones(Stream) Method and recognized text using  IOcrDocument.Save(Stream,DocumentFormat,OcrProgressCallback) Method.

The help topics for the above methods are available in our .NET help file.

If you need more information, please let me know what are the other things you want to save.

Please define "everything" exactly.
You already managed to save zones. What other things did you try to save but failed? Please give me full details about the feature you need.

My qustion is just like that:
I get ocrPageCharacters from the page after recognizing it.I save all zones/image/ocrPageCharacters of this page and restore them later.Do I need to recognize it again in order to get information about ocrPageCharacters(Bounds/CellIndex/Position?

If you want to save the recognized words or characters along with all their properties, you can do that, but there is no LEADTOOLS function to save all these values together. This means you will have to write your own code to save them and load them at a later time.

Or you can use IOcrDocument.SaveXml. This method and its overloads will save to a disk file or stream (or returns an XML string) the data you need.
Depending on the options passed, each element will contain data for page number, size and resolution. Zone location, type, modules. Character or Word info, confidence, etc.

Check out the online help of OcrXmlOutputOptions below for more info and a link to an example:
