PDFDocument

This is a wrapper for ReportLab which allows easy creation of PDF documents:

from io import BytesIO
from pdfdocument.document import PDFDocument

def say_hello():
    f = BytesIO()
    pdf = PDFDocument(f)
    pdf.init_report()
    pdf.h1('Hello World')
    pdf.p('Creating PDFs made easy.')
    pdf.generate()
    return f.getvalue()

Letters and reports

PDFDocument comes with two different PDF templates, letters and reports. The only difference is the layout of the first page: The letter has an additional frame for the address at the top and a smaller main content area.

Usage is as follows:

pdf.init_report()
# Or:
pdf.init_letter()

The letter generates default styles using 9 point fonts as base size, the report uses 8 points. This can be changed by calling pdf.generate_style again.

There exists also a special type of report, the confidential report, the only differences being that the confidentiality is marked using a red cross at the top of the first page and a watermark in the background.

Styles

The call to pdf.generate_style generates a set of predefined styles. (Yes it does!) That includes the following styles; this list is neither exhaustive nor a promise:

pdf.style.normal
pdf.style.heading1
pdf.style.heading2
pdf.style.heading3
pdf.style.small
pdf.style.bold
pdf.style.right
pdf.style.indented
pdf.style.paragraph
pdf.style.table

Most of the time you will not use those attributes directly, except in the case of tables. Convenience methods exist for almost all styles as described in the next chapter.

Content

All content passed to the following methods is escaped by default. ReportLab supports a HTML-like markup language, if you want to use it directly you'll have to either use only pdf.p_markup or resort to creating pdfdocument.document.MarkupParagraph instances by hand.

Headings

pdf.h1, pdf.h2, pdf.h3

Paragraphs

pdf.p, pdf.p_markup, pdf.small, pdf.smaller

Unordered lists

pdf.ul

Mini-HTML

pdf.mini_html

Various elements

pdf.hr, pdf.hr_mini, pdf.spacer, pdf.pagebreak, pdf.start_keeptogether, pdf.end_keeptogether, pdf.next_frame,

Tables

pdf.table, pdf.bottom_table

Canvas methods

Canvas methods work with the canvas directly, and not with Platypus objects. They are mostly useful inside stationery functions. You'll mostly use ReportLab's canvas methods directly, and only resort to the following methods for special cases.

pdf.confidential, pdf.draw_watermark, pdf.draw_svg

Additional methods

pdf.append, pdf.restart

Django integration

PDFDocument has a few helpers for generating PDFs in Django views, most notably pdfdocument.utils.pdf_response:

from pdfdocument.utils import pdf_response

def pdf_view(request):
    pdf, response = pdf_response('filename_without_extension')
    # ... more code

    pdf.generate()
    return response

The SVG support uses svglib by Dinu Gherman. It can be found on PyPI: <http://pypi.python.org/pypi/svglib/>
