.t ReportLab API Reference

.nextPageTemplate Normal

.h1 Introduction

This is the API reference for the ReportLab library.  All public
classes, functions and methods are documented here.

Most of the reference text is built automatically from the
documentation strings in each class, method and function.
That's why it uses preformatted text and doesn't look very
pretty.

Please note the following points:
.bu <seqdefault id='list'/><bullet>(<seq/>)</bullet>Items with one leading underscore are considered private
to the modules they are defined in; they are not documented
here and we make no commitment to their maintenance.
.bu <bullet>(<seq/>)</bullet>Items ending in a digit (usually zero) are experimental;
they are released to allow widespread testing, but are
guaranteed to be broken in future (if only by dropping the
zero).  By all means play with these and give feedback, but
do not use them in production scripts.

.h2 Package Architecture

The reportlab package is broken into a number of subpackages.
These are as follows:

.df <font name="Courier"><b>reportlab.pdfgen</b></font>
- this is the programming
interface to the PDF file format.  The Canvas (and its co-workers,
TextObject and PathObject) provide everything you need to
create PDF output working at a low level - individual shapes
and lines of text.  Internally, it constructs blocks of
<i>page marking operators</i> which match your drawing commands,
and hand them over to the <font name="Courier">pdfbase</font>
package for drawing.

.df <font name="Courier"><b>reportlab.pdfbase</b></font>
- this is not part of the
public interface.  It contains code to handle the 'outer
structure' of PDF files, and utilities to handle text metrics
and compressed streams.

.df <font name="Courier"><b>reportlab.platypus</b></font>
- PLATYPUS stands for
"Page Layout and Typography Using Scripts".  It provides a
higher level of abstraction dealing with paragraphs, frames
on the page, and document templates.  This is used for multi-
page documents such as this reference.

.df <font name="Courier"><b>reportlab.lib</b></font>
- this contains code of
interest to application developers which cuts across
both of our libraries, such as standard colors, units, and
page sizes.  It will also contain more drawable and flowable
objects in future.

There is also a demos directory containing various demonstrations,
and a docs directory.  These can be accessed with package
notation but should not be thought of as packages.

Each package is documented in turn.

The method Canvas.beginPath allows users to construct
a PDFPathObject, which is defined in reportlab/pdfgen/pathobject.py.

.h2 <i>reportlab.pdfgen.textobject module</i>

The method Canvas.beginText allows users to construct
a PDFTextObject, which is defined in reportlab/pdfgen/textobject.py.

.pageBreak
.h1 <i>reportlab.platypus</i> subpackage

The platypus package defines our high-level page layout API.
The division into modules is far from final and has been
based more on balancing the module lengths than on any
particular programming interface.  The __init__ module
imports the key classes into the top level of the package.

.h2 Overall Structure

Abstractly Platypus currently can be thought of has having four
levels: documents, pages, frames and flowables (things which can fit into frames in some way).
In practice there is a fifth level, the canvas, so that if you want
you can do anything that pdfgen's canvas allows.

.h2 Document Templates
.h3 BaseDocTemplate

The basic document template class; it provides for initialisation and 
rendering of documents. A whole bunch of methods 
<b><font name=courier>handle_XXX</font></b> handle document
rendering events. These event routines all contain some
significant semantics so while these may be overridden that
may require some detailed knowledge. Some other methods are
completely virtual and are designed to be overridden.

A simple document processor can be made using derived class,
<b><font name=courier>SimpleDocTemplate</font></b>.
