OCR failure when learning and testing images from PDF.
PDF to TIFF conversation in learning and testing is handled by imagemagick. This conversation results in a image below the recommend image quality. Currently learning and testing only supports imagemagick for conversion of PDF to TIFF.
Separate and convert PDF files to TIFF files prior to learning and testing. Make sure that files are TIFF compression group 4.
