Can pdfbox find a dimension in a pdf drawing, zoom up on it,
highlight it, and create an image file?
We get pdf engineering drawings from suppliers. We need to
programmatically zoom up on a specified dimension, highlight it, and
create an image file of the zoomed up view. How to specify the
dimension is unknown. Some dimensions might have the same text so not
sure how to differentiate. Suggestions welcome. Can pdfbox do this?

Posted by Tilman Hausherr <TH...@t-online.de>.
Yes it might be possible but this would be a real development. One would
first have to search by a word, then get the position. To get the
position, see the PrintTextLocations.java example, or the
DrawPrintTextLocations.java example.
Then one would have to create a viewer who can do zoom on a point (try
PDFDebugger) and show a part from an image (or we could create a
temporary cropbox and render that one only). However the rendering with
PDFBox is not very fast, so zooming would not work as smoothly as with
Adobe.
So it might be possible, but not out of the box.

Re: Can pdfbox find a dimension in a pdf drawing, zoom up on it,

Posted by Greg Hanowski <gr...@enventive.com>.
Thanks Tilman. I played around a bit with the pdf drawing and noticed
that if I do menu item Edit->Find and type in the dimension value, it
will find it and highlight it in blue background. Then if I click the
Zoom Up (+) icon, it keeps the highlighted dimension in the middle of
the screen as it zooms. That is exactly the behavior I am looking for.
Is it possible to do the same thing programmatically using pdfbox api?

I had a look with PDFDebugger and it's really just text and vector graphics.

Hi Tilman,
Oh, ok, I understand. I've uploaded a new pdf to here:
http://www.tekknow.net/MoneyMachine/386-5001.pdf
I created this pdf from the Creo 5.0 CAD system. It is not proprietary.
Thank you for checking whether the dimensions exist in a "dictionary"

Re: Can pdfbox find a dimension in a pdf drawing, zoom up on it,

Posted by Tilman Hausherr <TH...@t-online.de>.
Hi,
The problem is that I need an actual PDF to see whether these
"dimensions" exist as a dictionary somewhere (there are so many "exotic"
PDF features). If this is just a vector graphic then we can't fetch it
without OCR or pattern recognition.
I thought it had to do with viewports but now I think that isn't. A file
with it is in this question:

Re: Can pdfbox find a dimension in a pdf drawing, zoom up on it,
highlight it, and create an image file?
Posted by Greg Hanowski <gr...@enventive.com>.
That's just an example to help people understand what a dimension is and
what I'm trying to accomplish. The real pdf drawings are proprietary so
can't show them. But they will not be screen shots. They will be PDF
drawings generated by the CAD (Computer Aided Design) systems.

That's just an image in a PDF. No way to find that dimension
programmatically (one could use OCR, with all the difficulties)

Ok, I've uploaded it to here:
http://www.tekknow.net/MoneyMachine/drawing.pdf
I want to be able to programmatically zoom up on the "4 +/- 0.2"
dimension, for example, highlight it in some way (Put a transparent

the zoomed up view.

Hi,
nothing attached, you need to upload it somewhere. It would be useful to
have the PDF too. If you can't share it, then please create a dummy. Btw
I don't have Adobe Professional, only the reader.

I've pasted a screenshot of an engineering drawing. Dimensions are the
numbers that define distances between two points. I want to be able to
programmatically zoom up on the 12.000 dimension, for example, highlight
it in some way (Put a transparent yellow over it, or change the color of
it), then an image file of the zoomed up view.

With "dimension" do you mean a rectangle coordinate or this viewport
thing? (An exotic feature of PDF)
"Zoom up" - do you want to make it bigger? Or do you just mean to cut it
out?
Highlight = ? Put a yellow over it?
It is possible to crop on a specific area by modifying the cropbox of a
page, then only the cropped area will be seen. It's also possible to
highlight by filling a rectangle and blending this on top.
