Aw: Re: Type1Glyph2D No glyph for 41 (.notdef) in font Helvetica

[Andreas Lüdtke]

Hi John,
 
I tried pdfbox-app-2.0.0-20150203.010142-1018.jar this morning and I still get 
the Exception in thread "main" java.lang.StringIndexOutOfBoundsException: 
String index out of range: 0.
 
Can I help you fix this?

Betreff: Re: Type1Glyph2D No glyph for 41 (.notdef) in font Helvetica
Thanks Andreas. I tool a look at the arial.ttf file which you sent me and the 
problem was as I had suspected - Microsoft have changed the tables in the 
Windows 8.1 version of the font.

PDFBox relies on the PostScript glyph names in the ‘post’ table when 
substituting a TTF in place of a Type 1 font. However, the new Windows 8.1 
version of Arial uses a format 3 ‘post’ table which does not include any names. 
That means that every glyph lookup fails.

The solution is to extended FontBox's TrueTypeFont class to allow looking up of 
PostScript names by mapping them to entries in the ‘cmap’ table. I’ve opened 
PDFBOX-2650 to address this.

Thanks for taking the time to report this and provide the necessary details.

Re: PDF extraction

[Frank van der Hulst]

I agree with everything Peter has said.

My 'solutions' work for the tables I wanted to extract, but won't work for
others.

I think its common for a table to have at least one column which is present
in every row. I use that to break the table up into rows... when the X
position goes back to the left of this column it is (probably) a new row.

I have also used the header row of the table to identify the column limits.

Incidentally, it's also a good idea to strip out the page headers & footers
before trying to parse a table.

I'm happy for my work to be included in PDFBox as a starting point for
other people trying to extract tables.

Re: PDF extraction

[Peter Murray-Rust]

I agree with all those who emphasis that there is no deterministic
algorithm. I also agree that Tabula is likely to be the best place to start
and am working with them.

The first question is:

"How do you know where the tables are?"

In some cases you can look for the Anglophone word "Table", and a regex of
something like:
- "Tab(le)?\s*((\d+)|(IVXL)+) "
or you can look for
 - grid lines
or you can look for whitespace patterns:

Isthis
a table

or just fortuitous.

and some tables use zebra stripes.

I suspect at least 100 person years (and probably much more) have been
spent on trying to extract tables. If we take the heuristic approach then
it's work pooling our efforts and trying to share code. I'm sharing mine on:
https://bitbucket.org/petermr/svg2xml/wiki/Home (which is built on PDFBox
and https://bitbucket.org/petermr/pdf2svg/wiki/Home).

Other people have built systems that use adaptive methods to decide where
the whitespace is.

I'd recommend splitting the PDF2Character part (I use SVG for the modelling
syntax) and characters2tables as it means we can use more character
extractors and combine them with the table synthesizers.

P.

Re: [PDFBOX-2.0] Signature Issue

[Andreas Lehmkuehler]

Hi,


Am 29.01.2015 um 16:10 schrieb Isaias Barroso:

Hi Ruben,

I think it isn't the same problem, because the file is correctly signed
using PDFBOX 1.8.8 and BouncyCastle 1.45.
I guess the problem was a missing trailer. I've fixed that in the trunk, see [1] 
for further details.


Please, double check if everything is fine now.

What exact SNAPSHOT version did you use as there were recently some

Do you have any suggestion to investigate the root cause?

What exactly did you do to sign the pdf? Did you have a look at the
provided
testcase [1], which demonstrates all necessary steps to sign a pdf.

Re: PDF extraction

[Frank van der Hulst]

I have written a couple of Java classes that extract tabular data to arrays
of Strings.

One works where the location of each column is fixed. The other figures out
the locations of columns from the table headers and outline drawing.

The usual story applies... hardly any documentation, and they only work for
limited cases. I've sent the code to Lorena... I'd be grateful if you could
improve the documentation.

NB: I'll be out of reach of my computer (and therefore my source code) for
the next few days, but will probably still be able to answer emails.

Frank

Re: PDF extraction

[Tilman Hausherr]

Hi Lorena,

There is no concept of table in a PDF, except in a tagged PDF.

A table is just lines and text. In no specific order. It could also be 
an image of a table.


You can succeed in this only if you know the structure of the PDF in 
advance, e.g. when it all comes from the same client.

Re: PDF extraction

[Gilad Denneboom]

It might be possible to extract the text you want but I don't think there's
a built-in method in PDFBox that will allow you to do it. It will have to
be based either on the text's location on the page, the context (relation
to other text), a certain pattern, etc. Each of these things can be
implemented but it would require a custom-made tool to be created.
It's very hard to say for sure without seeing the actual file, though.

PDF extraction

[Lorena Leishman]

Hi,
I have a PDF that has information displayed on tables. Example:
Company Name:   Barnes & Noble   Bank Of America  Macy'sAccount #:             
123x              345               679Status:                   
Open                    Closed                 OpenBalance:                $23. 
                     $0.00                    $100
Is there a way with PDFbox to extract a specific value(s) from the table? 
Example: Bank Of America  and $0.00 
And also is there a way to cut the whole table and paste it into a different 
PDF?
Please let me know, Thanks!

Re: Release schedule 2.0.0

[Maruan Sahyoun]

Hi,

we are currently looking at coming up with a release date reviewing the issues 
we have and moving the ones we will not be targeting into subsequent releases.

This is the list of (currently) open issues targeted to be handled in 2.0  
https://issues.apache.org/jira/browse/PDFBOX/fixforversion/12319281/?selectedTab=com.atlassian.jira.jira-projects-plugin:version-issues-panel

If you feel there are issues you can help with yes please, let us know. The 
easiest would be to add a patch to the issue. If you can respect our coding 
conventions https://pdfbox.apache.org/codingconventions.html that would be 
great.

Feel free to ping me towards the end of the week if there is no progress.

Hi,

as i did not get an answer, i assume there is no planning yet ? Would it 
be possible to tag a version as release candidate or milestone instead ?
I would be willing to dedicate a small amount of time if that helps, but 
the list of open issues for this version is daunting (100+). Please let 
me know if there is anything i can help with (as a java programmer, not 
a pdf specialist).
Btw, the product works fine for me, so thanks to all developers for
