I have scaned PDF document with text created by OCR engine embended in Xerox WorkCentre 7535

You can get this testing PDF here:

http://lipok.pl/Debenu/DOC_20180417150838.pdf" rel="nofollow - http://lipok.pl/Debenu/DOC_20180417150838.pdf

When I open this PDF in AcrobatReader and select all copy... paste to notepad then I see quite good extracted text.

But when I use GetPageText with ExtractOptions = 7 then the text is scattered.

Do you have idea how to fix it ?

btw.

It seams that Option 7 is "broken" as using option 8 will properly place word "Komornik" at the the top of extracted text, instead down in option 7.

Hi,

option 7 works on the principle "first in - first out".
If you make a correction on the first row of a finalized pdf-document these correction will be extracted at the end cause it was inserted last.

Option 8 is doing the extraction in a readable format (taken the position data of each string into account) and extract row by row.

You can do it like option 8 by your own if you're using option 2 or 3 - calculating strings to rows...

Cheers,

So it would be good to get new feature/option 9 to extract in a way which will be combinaton of option 7 and 8, which will do exactly what you say in your last statement.

Of course I post feature request to Debenu.

Thanks.

btw. I'm already in development proces to do what you say, I just now trying to calculate positions and keep this text toogether.
