Open and scan pdf


Recommended Posts

Hello,

I'm trying to build a vi that is able to open and scan (search within) a pdf file.

Opening a pdf file with the use of ActiveX (class:iacroaxdocshim) is no problem.

Is there a possibility to open and scan (search within) pdf files using labview and how do I do that?

Thanks in advance

Yes, it can be done, but not in a straightforward way, AFAIK. When I did it some time ago, I used a (free) utility 'pdf2txt'. Google will show you where to find it. I called 'pdf2txt' with LV's 'System Exec.vi' to generate a temporary txt file, which then could be opened and analysed.

If I find my old VI I'll post it here..though it's not difficult to rewrite it once you have the pdf2txt.exe.

Thanks, will it also work with pdf's containing text and drawings?

It will work with all pdfs, but of course only text will be converted.

And don't expect that it converts all text correctly. Ligatures, e.g., are not converted AFAI remember. You've got to try it...
