here the full stack trace.
If I remove all pdf.add_text_wrap commands, and I leave only draw
command (like
pdf.fill_color(Color::RGB.from_html(''#E6E6E6;''))
pdf.rectangle(left, cur_y-4, 610, 15).fill
pdf.line(left+70, cur_y-4 ,left+70, cur_y+11).stroke
no error happenz
Thanks, Tomaso

Re: PDF::Writer Switching to Production Trouble (on rails)
I''m using "Times-Roman", and if I wrote on ./script/console require ''pdf/simpletable'' pdf=PDF::Writer.new pdf.select_font "Times-Roman" pdf.add_text_wrap 100, 100, 400, "Aula", 15 pdf.render no error happen... only in production mode, on apache fcgi... Is possible a misconfiguration on www-user? PDF::Writer use some ENV variable? root and ww-user have same shell (bash) on /etc/passwd something else? Really, I''ve no idea... Trouble only on apache/fcgi... Argh!

No way! I''ve decided to run application in development mode under apache/fcgi, but using production environment, i.e. whith cahing class: config.cache_classes = true config.action_controller.consider_all_requests_local = false config.action_controller.perform_caching = true If I call development mode with other name (for example new_state), and I correct database.yml and environments/new_state.rb the error become like production mode.... Than I set DefaultInitEnv RAILS_ENV development and no preoblem found. If someone know differences between devlopment status and other status (production or elseware) tell me where I can read about it (nothing in agile web and rail recipes) Thank you Austin, right way is the problem in Rails...

PDF::Writer do not work properly in fcgi mode, in linux.
The trouble is in PDF::Writer::FontMetrics class that try
to read afm in binary mode and do some operations that is
prohibited in fcgi.
The solution is the creation of rfm file who is only
unmarshaled. This workaround has beautiful side effect to
increase the performance of pdf generation.
Here the snipplet (whith Times-Roman):
cd <your application>
./script/console development
>> require ''pdf/writer''
>> p=PDF::Writer::FontMetrics.open("Times-Roman")
>> p.save_as_rfm
>> exit
mv Times-Roman.afm.rfm \
/usr/lib/ruby/gems/1.8/gems/pdf-writer-1.1.3\
/lib/pdf/writer/fonts/
To made this for all the fonts, simply execute in console:
Dir.foreach(''/usr/lib/ruby/gems/1.8/gems/pdf-writer-1.1.3/lib/pdf/writer/fonts/'')
{|d|; if d=~/.afm$/; p=PDF::Writer::FontMetrics.open(d); p.save_as_rfm;
end }
and copy all to destination
mv *.rfm /usr/lib/ruby/gems/1.8/gems/pdf-writer-1.1.3\
/lib/pdf/writer/fonts/
Hope this is useful...
