Please note that I try to run the ocr but the program close as it start to use the tesseract ... (I try with/without GUI) and I try 64-32 and the old cpu versions

please find attachment of the cmd error that I get before it close.

Thanks. I'll post a fix soon. It has to do with the Tesseract v4 code not being especially resilient when compiling/detecting SSE/AVX capability.

I have posted some beta Windows builds [link removed since release of v2.51]. I'd appreciate if somebody could try them on a relatively modern PC with Tesseract OCR and let me know (1) if the OCR works and (2) what the header says (SSE? AVX?).

Hello!

I did not expect new release, otherwise, I would inform you about another issue with source code.

Problem happens sometime, when here is only one element recognized on text line (happens for titles and right aligned epigraphs) then 'wrmap' not aligned properly. As result text detected correctly, and page formed normally, but when I ask for back coordinates (original coordinates on source image) I got wrong results. It happens because 'wrmap' malformed during parsing.

Check this fix:

Can you post an example source PDF and the conversion settings where this fix made a difference? I'd like a test case.

You can choice any pdf with centered or right aligment text. The one I'm using is DVJU (hope russian and djvu it is not an issue) https://drive.google.com/open?id=1rH...2pJAFuKN-y9men

Page 2 has title text and ISBN number center and right aligned. When you parse this page, and request coordinates for title (Бэтман Аполло) and isbn (ISBN 978-5-699-63446 -0) text lines it will return left aligned coodinates.

If user click on screen using those coordinates it will not select text on source image properly because coordinates are incorrect.

Convert settins default, and screen size = android screen size, not important, any small screen will suffice 1080x1920

Axet--can you please send me a private message with your e-mail address? I'd like to have further discussion but don't want to clutter the thread.

See the k2pdfopt FAQ, fourth from last question: "Sometimes I get multiple rows of text at smaller magnification than the rest of the document. Why?" The bottom line is you'll want to put something like:

-gtr 0.1

In the "Additional Options" box. This will encourage k2pdopt to break lines apart more readily. You may have to adjust the number larger or smaller. The default is 0.006. Larger gives more encouragement to break apart the lines.

k2pdfopt v2.51 released
K2pdfopt v2.51 is released. This fixes an issue in v2.50 where the Tesseract OCR would not run on modern PCs and enhances the accuracy of the Tesseract v4.0.0 OCR. See details at the web site.
