Hi,

I'm using text extraction functions (activex v7.22 b2) to extract words with coordinates.
I'll need to extract full-line text with line coordinates. Do I have any solution for doing this?

Hi Alin!

QuickPDF doesn't have this option but it will support you...
You can extract complete pages, strings like they were inserted and single words.
Take the word-option and concatenate the complete lines regarding the position data of each word.
If you have this algorithm completed please insert it here in the samples-section 'cause i need it, too ;-)

Cheers and thanks in advance,
Ingo

Hi Ingo,

Thanks for you answer. I'll post the algo soon; I have some problems with the tables (the OCR engine "read" tables by line/column about a random?! criteria).

Hi Ingo,

I've posted a basic sample (see code sample) of text assembling lines based on Y1 or Y2 coordinate of words (GetPageText(4) function); for a more accurate result, I think that it'll need a control variable for Y coordinate different values for the words of the same line.

Cheers,
Alin
