Hi, I have tried again to use fpdf.
*1st try:*
from gluon.contrib.fpdf import FPDF
def test():
pdf = FPDF('P', 'mm', 'A4')
pdf.add_page()
pdf.set_font('Arial', 'B', 16)
pdf.cell(40,10,'Hello World')
response.headers['Content-Type'] = 'application/pdf'
return XML(pdf.output('', 'S'))
Ok, that's simple and it works fine.
*2nd try:*
Now I want to use the unicode version.
There is a example: https://code.google.com/p/pyfpdf/wiki/Unicode:
*Before you can use UTF-8, you have to install at least one Unicode font in
the font directory (or system font folder).*
But there is no font directory in fpdf!
It would be nice to have a complete example how to use fpdf in web2py!
After some trials I had to copy the *font directory* containing a lot of
"DejaVu*"-files to the gluon/contrib/fpdf directory.
The structure is: gluon/contrib/fpdf/font
from gluon.contrib.fpdf import FPDF
def test():
pdf = FPDF('P', 'mm', 'A4')
pdf.add_page()
pdf.add_font('DejaVu', '', 'DejaVuSansCondensed.ttf', uni=True)
pdf.set_font('DejaVu', '', 14)
pdf.cell(40,10,'Hello World äöü€')
response.headers['Content-Type'] = 'application/pdf'
return XML(pdf.output('', 'S'))
And now I get an error message:
<type 'exceptions.ValueError'> could not convert string to float

What is the right way to use fpdf with the whole unicode character set in
web2py?
Regards, Martin
