Sanaviron is an 2D drawing engine fully written in Python for represent composite vector graphics. This is essentially a GTK+ Cairo based canvas. The effort focuses mainly on the design of budgets, invoices, labels and many other types of commercial documents. Sanaviron offers a simple but powerful high level API that you can implement in their programs. This widget can be used for flexible display of graphics and/or creating documents interactively. Sanaviron is a GTK+/Cairo dependent component, so it is portable to many plataforms. Sanaviron is 100% pure Python, but because the libraries used, it is easy to translate into ANSI-C using GObject mechanism and much easier to translate into C++.

A list of features can be highlighted as:

• Paper and margins.
• Grid.
• Snap over grid.
• Object movement.
• Multiple objects selection.
• Multiple objects movement.
• Object resizing through cardinal control points.
• Object distortions through limbus control points.
• Simple extension and creation of new objects.
• Good OOP abuse
• Geometric concepts with greater understanding level.
• Barcode support.
• Statical charts based on PyCha (vertical and horizontal bars and stacked bars, pie, lines and points).
• PDF and PNG export capability.

And recently added features:

• Python 3.4
• GTK 3.x
