Is it possible to extract text from a rendered page based on a user-defined bounding box?

Thanks.

Hi Mark!

A rendered page means an image for me.
So it's not possible to extract text from it...?

Cheers and welcome here,
Ingo

Ingo, thanks.

What about extracting text from the real page based on a defined boundary box?

You can use SetTextExtractionArea to limit the extraction results.

If you are wanting to perform multiple extractions from the same page then it would be more efficient to process the bounding box results from GetPageText(3) or (4) yourself which is quite easy to do.

If you can highlight and select (copy/paste) text using Acrobat Reader then it should be possible to use GetPageText to perform text extraction. Many image based documents have been processed using OCR.
