Nov 29, 2010 at 1:21 PM

I have a PDF file which includes the blank black page.

We convert all the PDF pages into TIFF file to apply the OCR.

All the page which are having white background get processed successfully, but for Blank and Black background images it gives the error like

---------------------------

Error

---------------------------

GREY: TOO MANY LINES (8400)

---------------------------

OK  

---------------------------

---------------------------

Error

---------------------------

GREY TO:

NOT OPEN 0,0

---------------------------

OK  

 

Please let me know if u have any solution for the same.

 

Thanks

I would suggest you examining an image to contain black background prior to recognition (ration of white pixels to black) and inverting it if necessary. I'm not sure if any other options (specifically within Puma.NET) are available.
