Major differences between PDFTextStripper and PrintTextLocations
Hi everyone,
I'm looking for advice on a problem I'm encountering where the output of
PDFTextStripper and PrintTextLocations is dramatically different when
processing the same file.
For some reason, the output of PrintTextLocations is 12 times longer than
that of PDFTextStripper, ie the entire text is printed out 12 times,
instead of just once.
I'm attaching the file in question, as well as the output produced using
both methods via Google Drive... Hopefully it will come through.
I'd appreciate any ideas as to what might be causing this issue (I'm
guessing there's something wrong with the structure of the file), and of
course any possible solutions.
Thanks in advance, Gilad.
PS. I'm using 1.8.10.

OK, thanks for looking into it, any way!

I guessed it was something like that... Do you think it's because it was
generated with iText?

The pdf contains a lot of redundant information, e.g. the header is repeated
several times (I didn't count them but I guess it's 12 times). PDFTextStripper
eliminates overlapping text/characters and PrintTextLocations doesn't.

Re: Major differences between PDFTextStripper and PrintTextLocations
Posted by Gilad Denneboom <gi...@gmail.com>.
Hi Andreas,
Of course the output itself is different, but I would expect that the
underlying text each tool processes would be the same, and it's not. Have a
look at the first line in the PrintTextLocations output file:
String[472.89,54.0 fs=10.0 xscale=10.0 height=7.21 space=2.5
width=2.7799988]:
It is repeated, with exactly the same information, 12 times throughout the
output, lines 1, 91, 181, 271, 361, 451, 541, 631, 721, 811, 901 and 991.
Why would the same information be processed 12 times in a single run?

Hi Gilad,
sorry for the late answer ....
I'm not sure what you're expecting. You are using 2 totally different approaches
to process a pdf. PrintTextLocations provides a lot of additional information
for every piece of text, which may vary from one character up to whole words or
lines of text. Consequently the output has to be totally different and of course
much bigger than the output of a simple text extraction.
