Hi to all, does anyone know what is the file osd_pxvocr.dat? is stored in this archive http://www.tracker-software.com/downloa ... rt_OCR.zip (OCR languages for Portable version). I noticed that in the Portableappc version is not present (only four language files, I added italian from http://www.tracker-software.com/OCRAddi ... angsEU.zip and seems ok). The file osd_pxvocr.dat may be is necessary, I'm not sure. Thanks to all.

I am not sure too but I think it is necessary. Anyway it is no harm to put in an extra file if not require.

osd_pxvocr.dat seems to be related to the Orientation & Script Detection (OSD) function of Tesseract OCR, which uses osd.traineddata (download from: https://github.com/justin/tesseract-ocr ... raineddata ).

Perhaps osd_pxvocr.dat is PDF-XChange Viewer's ("pxv") amended proprietary equivalent of osd.traineddata.

OSD is used by Tesseract OCR engine to analyze the text script (writing direction, textline order), as well as dominant page-orientation of the image to be OCR'ed.

If the OSD data file is missing, the application may fail to accurately OCR image files whose text is arranged in different directions & orders (eg. tables, essay with indented paragraphs/quotes, maps, etc.)
