Problem with HTML_ToPDF class (PHP)

Hello!

In my project, I'm using HTML_ToPDF PHP class, which uses html2ps script to convert from HTML to PDF file.

Recently I upgrated my production server to Debian 5 (lenny) and, after that, HTML_ToPDF is no longer working:

convert() method from HTML_ToPDF class is returning this error:

Error: there was a problem running the html2ps command.  Error code returned: 127.  setDebug() for more information.

And, the output from html2ps call is:

/usr/bin/perl: symbol lookup error: /usr/lib/perl5/auto/Compress/Zlib/Zlib.so: undefined symbol: Perl_Tstack_sp_ptr

Any help would be appreciated, thanks!

[Edited] After some tests, I've found that the problem happens only with HTML containing images ( tags). When html2ps founds the first image it crashes. Converting HTML without images works fine. Any idea? Thanks!

From stackoverflow

• This is an issue with the initial conversion from HTML to PS. Usually due to poorly written HTML.

  Can you show some examples of what you are trying to convert?

• To be honest I've found wkhtmltopdf to be far better than html2ps, even though it's at a fairly early stage of development.

  I wrote a blog about it, but if you don't want to read that basically it uses KHTML/Webkit's rendering engine to render the page which is a bit more sensible than the usual approach of writing a complete HTML renderer.

  The distributed binary worked just fine on my Debian server, and frankly the results are excellent.

  Ciaran McNulty : It is a worry, but it's only a 'temporary' X-server and isn't using a huge framebuffer - I'd have to do some profiling vs. html2ps before I assumed it was more impact. Thanks for the click though!
