FPDF (and PyFPDF) is a library with low-level primitives to easily generate PDF documents. This is similar to ReportLab's graphics canvas, but with some methods to output "fluid" cells ("flowables" that can span multiple rows, pages, tables, columns, etc.). It has several methods ("hooks") that can be redefined, to fine-control headers, footers, etc.
Originally developed in PHP several years ago (as a free alternative to proprietary C libraries), it has been ported to many programming languages, including ASP, C++, Java, Pl/SQL, Ruby, Visual Basic, and of course, Python.
For more information see: http://www.fpdf.org/en/links.php
This library is not a:
- charts or widgets library (but you can import PNG or JPG images, use PIL or any other library, or draw the figures yourself; see examples)
- "flexible page layout engine" like Reportlab PLATYPUS (but it can do columns, chapters, etc.; see the Tutorial)
- XML or object definition language like Geraldo Reports, Jasper Reports or similar (but look at write_html for simple HTML reports and Templates for fill-in-the-blank documents)
- PDF text extractor, converter, splitter or similar. Look at pyPdf.
Compared to other solutions, this library should be easier to use and adapt for most common documents (no need to use a page layout engine, style sheets, templates, or stories...), with full control over the generated PDF document (including advanced features and extensions).
It is smaller (a source folder less than 200K) and compilation or external libraries are not required.
It includes cell and multi_cell primitives to draw fluid document like invoices, listings and reports, and includes basic support for HTML rendering.
Following is an example similar to the Reportlab one in the book of web2py. Note the simplified import and usage: (http://www.web2py.com/book/default/chapter/09?search=pdf#ReportLab-and-PDF)
PyFPDF:
from fpdf import FPDF
def get_me_a_pyfpdf():
title = "This The Doc Title"
heading = "First Paragraph"
text = 'bla ' * 10000
pdf = FPDF()
pdf.add_page()
pdf.set_font('Times', 'B', 15)
pdf.cell(w=210, h=9, txt=title, border=0, ln=1, align='C', fill=0)
pdf.set_font('Times', 'B', 15)
pdf.cell(w=0, h=6, txt=heading, border=0, ln=1, align='L', fill=0)
pdf.set_font('Times', '', 12)
pdf.multi_cell(w=0, h=5, txt=text)
response.headers['Content-Type'] = 'application/pdf'
return pdf.output(dest='S')Reportlab:
from reportlab.platypus import *
from reportlab.lib.styles import getSampleStyleSheet
from reportlab.rl_config import defaultPageSize
from reportlab.lib.units import inch, mm
from reportlab.lib.enums import TA_LEFT, TA_RIGHT, TA_CENTER, TA_JUSTIFY
from reportlab.lib import colors
from uuid import uuid4
from cgi import escape
import os
def get_me_a_pdf():
title = "This The Doc Title"
heading = "First Paragraph"
text = 'bla ' * 10000
styles = getSampleStyleSheet()
tmpfilename = os.path.join(request.folder, 'private', str(uuid4()))
doc = SimpleDocTemplate(tmpfilename)
story = []
story.append(Paragraph(escape(title), styles["Title"]))
story.append(Paragraph(escape(heading), styles["Heading2"]))
story.append(Paragraph(escape(text), styles["Normal"]))
story.append(Spacer(1, 2 * inch))
doc.build(story)
data = open(tmpfilename, "rb").read()
os.unlink(tmpfilename)
response.headers['Content-Type'] = 'application/pdf'
return dataYes, if you use web2py, you can make simple HTML reports that can be viewed in a browser, or downloaded as PDF.
Also, using web2py DAL, you can easily set up a templating engine for PDF documents.
Look at Web2Py for examples.
This library was improved over the years since the initial port from PHP. Some code is in early development stages (mainly UTF-8 support and some advanced features). The good news is that PHP versions and examples are available from a long time ago, so migration and some bug-fixes are easy.
Said that, a former version is working successfully and is commercially supported since late 2008 for electronic invoice templates compliant with AFIP (Argentina IRS) normative, in several environments (Linux, Windows, etc.). It was originally included in PyRece, with thousands downloads to date.

In contrast, write_html support is not complete, so it must be considered in alpha state. Further enhancements using web2py helpers and an XML parser will enable parsing more complex HTML files.

Other FPDF derivatives also choose LGPL, such as sFPDF by Ian Back.
