Hi Nick, I tried passing in the CCITTFaxDecode data to tesseract, but it was not detected as TIFF.
It seems like CCITT fax is not same as TIFF. Google search showed me that few other people also faced same issue (e.g. " http://stackoverflow.com/questions/2641770/extracting-image-from-pdf-with-ccittfaxdecode-filter "). If you know, how we can convert the CCITT-Fax to tiff or jpeg, it would be really helpful. Many thanks for your help and time.
