The PDF creator should be providing that table, called the ToUnicode
map, in the font's data structures. Since this font doesn't provide one,
poppler has to guess what the Unicode value could be and it guesses
wrong.

If you were to provide a map that says, for this font, character code
"^A" maps to "β", that should work.

It's an optional feature. If built with libcurl, the poppler utils can
load a document over the internet.

Generally people install it though their distro if using Linux or BSD.
Through msys2 or cygwin for people using Windows. Through Homebrew or
MacPorts for Mac. You can also compile from source, which is the .tar.xz
file.

> Will the installation take place on my local computer or on the server?

It will be installed on whichever computer you run the installer on, I
assume. That's out of scope of the poppler project since we don't
provide an end-user installer, we just provide the source code.

They are command line tools so you run a terminal and type the command.

I don't know how you use poppler in your project, but you may also have
the option of passing in the path when you construct the GlobalParams

The encoding files are in the poppler-data package, not the poppler
package.  Likely your users need to install poppler-data.

On Mac and Linux the path is hardcoded at compilation time.  It's
generally in /usr/share/poppler on Linux.  Not sure what the standard is
on Mac.  On Windows it looks in \share\poppler relative to the
installation directory.

Probably the manpage and --help text are inaccurate and should say PPI

For the benefit of the discussion, I'll repeat and expand on what I said
on the evince mailing list.

This document does not embed fonts, which means that poppler uses
fontconfig to locate appropriate substitute fonts.  If fontconfig can't
find the right combination of bold and italic, it will select some other
non-italic or non-bold variant.  My system, and apparently also William
Bader's system, at least show the bold font but not the italic font
because we have a bold CJK font installed.  I don't think that poppler
tries to synthesize font styles.

The pdf reference does mention that font styles can be synthesized, and
this might be what acroread is doing, so it would be nice if poppler
could synthesize bold or italic font styles.

There is no commercial licensing.  Poppler is licensed under GPL
versions 2 or 3.  You are free to use it as long as you comply with the
GPL, which in short means that if you distribute the poppler software or
some product that includes the poppler software, you also have to share
the poppler source code, the source code of any modifications you make,
and the source code of any programs which use poppler, also licensed
under the GPL.  Read the GPL for more information.

I don't know what is needed for a RIP so I can't say whether it is
suitable for that purpose, but the poppler maintainer will consider any
patches you provide.

I do think that this should have been publicly discussed before it was
adopted.  According to Daniel Stone's recent email¹ on the xdg list,
this was discussed privately by the fd.o admins, but I believe there
should also have been a public discussion period.

However, I think having a CoC is good and I don't see anything I
disagree with in the CoC.  I would prefer that it be more explicit,
especially regarding how enforcement and complaints are handled, but
overall I agree with it and I don't think that poppler should leave fd.o
because of this.

GNOME's bugzilla is at https://bugzilla.gnome.org.  For feature requests

it's not something that can just be fixed in the Debian packaging.

And yes, Debian's bug tracker is tricky.  It's what happens when you

Have you actually installed poppler?  The behaviour you mention sounds
like the way libtool scripts set up the environment so that the correct
libraries are used by a not installed application.  But that's really
only meant to be used in a development environment.

I expect that if you have actually installed poppler, by using "make
install", that the binaries would instead be placed in somewhere like
/var/task/poppler/bin, they would be real binaries instead of libtool
scripts, and they wouldn't be trying to write to a .libs directory.

Poppler has worked with Helvetica for a very long time.  On Windows, it
should be mapped to the arial fonts.  I don't know why it's failing in
your case, but you could compile the source yourself and step through
the code to find why it's not working.  I would start with
SplashOutputDev::doUpdateFont in the file poppler/SplashOutputDev.cc
since I think that's where that error message comes from.

And no, we don't distribute binaries ourselves, only the source.  I
don't have much experience compiling things on Windows so I probably
won't be able to help with any compilation errors.  I understand cmake
is involved and lots of fiddling with dependencies, but not much else.

From what I can tell looking at dissambly, linking with libpoppler will cause a
mingw printf function to be used, otherwise a printf from msvcrt is used.

I'm not familiar with compiling for mingw or devlibs, but I'd be curious to see
if you run that test program in a debugger and step into the printf function or
try the command "info symbol printf" from gdb, to see where the printf function
actually goes.

You can't get a commercial license of poppler.  The copyright is owned by
dozens of people and you would need to contact each of them individually to
work out an agreement.  Poppler is a fork of xpdf though, and you might be able
to get a license for xpdf.  I think you can contact them at
www.glyphandcog.com.  You would of course lose any modifications or
improvements that have been made in poppler.

I don't think you've missed anything.  According to the spec, it looks like you
should be able to uncheck the boxes.  I've also found various forum and mailing
list posts complaining about that feature not working in Adobe Reader, or only
working in certain versions.  It looks like the only way to get that behavour
is to remove the radio flag, so they're check boxes instead.

If the number of pages is huge, the PDF might be intentionally
corrupted to provoke a bug in a particular PDF viewer, and other
data structures could be subtly corrupted as well. Any scan would
have to proceed very cautiously.

If there is a minimum number of objects required for a page, and if
the total number of objects is easy to find, could poppler
immediately reject files with (total num objects) / (min objects per
page) < page count?


The document at
https://drive.google.com/open?id=0ByTyiZeyQ4p9cTVBUllNRmI3bmM is what
I'm thinking of.  It has 5 objects and a single page that is listed in
the /Kids array 10 times.  Duplicating the page just means adding it
to the array again and incrementing /Count.  If we want this document
to work then there's really no minimum number of objects required for
a page.  Otherwise, each page would require at least a /Page object.

FWIW Adobe Reader shows an error on the document after the first
duplicated page.  Other viewers show it just fine.

pdftohtml can work with those languages but it depends the ability to
extract the plain text from the document.  From the couple of PDFs I've
looked at, they have problems with text extraction.  Possibly poppler
could do a better job, but as several application I tried have problems
extracting text from those documents, it's probably just a problem with
those documents.

I assume that PDF.js just works in a different way and doesn't require
the extracted text to be correct.

Instead of imposing an arbitrary limit we should just add a check for
gmallocn() returning NULL and print an error.

For broken PDFs that report an invalid size (see bug 85140) we could
check if the page count exceeds the number of objects in the XRef.


By the way, bug 91353 is also about an invalid (fuzzed) PDF claiming 
millions of pages.  I thought about maybe walking the page tree to count 
pages if the count seems unreasonable but it didn't seem worth the 
effort.  I like your idea better.

 Hi Jason,
 
 That makes a bucket load of sense, I've been just linking to a generic

 However the problem is, is that when I built codeblocks poppler project, it
 only created the libpoppler.dll.a and libpoppler-qt4.dll.a files. And
 while there is a cpp folder in the build directory it is only populated
 with folders that have to do with Cmake (CMakeFiles, cmake_install,
 CTestTestfile etc...).
 
 Do you have any idea why this might be the case? Is it for example that the
 C++ front end needs particular dependencies and if Cmake doesn't find them
 it doesn't build the C++ front end? If so do you know what the dependencies
 are for the C++ front end?

Sorry for the delay.  I have been without internet access for a few
days.  Also, please send your replies to the mailing list.

I don't know why it didn't build libpoppler-cpp.dll for you.  I just
tried with CMake and CodeBlocks on Windows and it built the library.

Yes, if the dependencies are not available, or if ENABLE_CPP is
disabled, it will not build the CPP frontend.  The only dependency I
am aware of is Iconv.  CMake should state whether the 'cpp wrapper' is
being built when you configure it.
