To all of you,

I believe i saw functions allowing to extract text from a page using a rectangle coordinates, and another allowing the getextracttext from the top to the bottom.

Did i dream?

If not, are these functions only in the 8.xx release (currently i'm a 7.26 user)

Thanks in advance for your help

Hi,

no dream, but as you assume:

DASetTextExtractionArea / SetTextExtractionArea

Version history
This function was introduced in Quick PDF Library version 8.13.

Description
Sets the area for text extraction. Any text that appears outside this area will be excluded from the results.
This function affects the results of the ExtractFilePageText and DAExtractPageText functions only.
The coordinate values passed into this function are specified in points with the bottom left corner of the page as the origin.
The area limitation can be removed by calling this function with a value of zero for both the Width and Height parameters.

Cheers,

Werner

You can extract the full page text and then extract only the text you need based on the bounding box data returned from GetPageText(3);

DASetTextExtractionArea / SetTextExtractionArea was added to make it easy to extract 1 or 2 pieces of text quickly but the process is not optimised for extracting 20 values for example. If you need to extract many values then it would be better to write your own simple rectangle checking routines.
