Dear Glen,
PDFStreamParser is only for parsing PDF content streams (so specific parts of a
PDF) and not the complete PDF. As a starting
point take a look at CustomGraphicsStreamEngine and or CustomPageDrawer in the
examples package.
Also PDFTextStripper will give you some ideas how to process
I'm trying to examine an existing PDF file. Initially to extract text and
maybe images, but ultimately to apply some logic to the formatting of the
text to turn it into valid HTML with H1, H2, ul, li, etc. I thought I
would start like this:
PDFStreamParser sParse = new
Thank you all. You do a great service.
I am up and running.
Thanks,
Pulkit

I understand the point about XObjects and how pdfBox might be missing the

I am hoping someone here might have had luck making pdfBox get data from

Pulpit,
I did not say that in your document the XObjects are images, I said that
they usually are just images. When you analyze 100 random PDF documents,
changes are that that most of them only use the XObject construct for
images and vector graphic, not for elements that contain text. Your

主题: Re: Spaces are ignored when read
just an idea from whom is not fluent in pdfbox nor PDF.
if you just want to know there is a space in between the letters and not
the amount of spaces, you can use your code to get character details and
then use extractText to get the words.

That's not correct, spaces exist but in most
Andreas,
That is very helpful.
I can get the x location of each character using TextPosition.getX(), ex:
W: 102.88399
i: 114.18165
t: 117.660614
h: 121.55801
d: 133.09477
u: 140.3994
e: 147.60838

Andreas,
You're absolutely right. I am testing it now, but it seems very complicated.
I hope there might be another easier solution.

Spaces don't exist as characters in PDFs. To identify spaces, you have to
compare the X coordinates of adjacent characters against their widths.

Hello ,
I have a PDF file created using Latex. I am trying to read and print all
letters in that file using PDFBox, but when doing this all spaces in that file
are ignored. Here is the code I am using:

Clovis,
Thanks a lot :)
I will have to follow this solution if there is no alternative. The problem
is that if I am extracting text of 500 or 600 pages PDF, that will consume
much additional memory and time. In addition I guess it's only a special
case for latex books only.

Tilman,
I am using this code to extract the text from the pdf because I need font

I have checked the PrintTextLocations.java example. I have tested using this

I’m rather confused by this thread, inferring spaces is one of the the main
features of PDFTextStripper. I’m not sure why anyone is suggesting to process
the text manually - there’s no need to do that. We do that already!
Looking at the original code the problem is right here:
