Different outputs of the Tiff image and the portion of it

[thakobyan]

Hello,

I use Tesseract-ocr 3 in my .Net application. When I process the entire TIFF file I get the data with missing portion. Then if I cut that portion from the image and process only that portion I can get the data from it. Attached full.tif and portion.tif are the samples I experience this problem.

When I OCR full.tif the digits on portion.tif are not recognized, but when I OCR portion.tif the whole data is recognized just fine.

Please advise.
