Highlighting, Zoom, and Text Search

Hello all,

 

I am trying to create a PDF Document Reader using PDFBox that supports
highlighting, text search, and zoom. Is this possible with PDFBox? Are
there any examples out there that demonstrate how to do these three
things? (I didn't see any examples that demonstrate this in the
src/main/java/org/apache/pdfbox/examples folder)

 

Thanks for your help,

 

David

Locating specific text in a PDF

Posted by David Myers <D....@astronautics.com>.

Hello,

Does anyone know how to locate certain text in a PDF? Does anyone know
how to determine the height and width of this text too? (I'm trying to
implement highlighting as described in section 3 on this page
http://pdfbox.apache.org/userguide/highlighting.html)

Thanks in advance,

David

Can anyone help me with this? Is there some demo code out there that
does this?

Thanks,
David

AFAIK there are 2 possible solutions:

- extract the text with [1] and just search in the result for your self
- use the integrated lucene search engine [2]

Have a look at the PDFREader [3]. It's a simple PDF doucument reader. It uses 
PDPage.convertToImage() to create an image for each page. It should be easy to 
add zooming using Java2D.

Hello David

I'm not really an expert of PDFBox...

I can tell you that text search is possible (I use it for text-extraction)

Highlighting seams also possible:
http://pdfbox.apache.org/userguide/highlighting.html

Zooming I don't know...
You could perhaps first convert the page as image 
(PDPage.convertToImage()) and than you can zoom the image...

Best regards,
Patrick
