I am currently working on getting text from scanned pdf and split it into several chunk by page. I read API documents but I can't figure out how I can do this. Following is my code ```
document.AddImageFile( imagePath, null, null );
document.Process( documentProcessingParams );
fulltext = document.getPlainText().getText();
return fulltext; // I would like to get fulltext by page
``` Would you please let me know how to do this. Thank you very much.
