Project Description

Papyrus is a 2D C++ scenegraph (canvas) library that utilizes the cairo library to perform drawing operations. Similar canvas libraries are the Gnome Canvas, Diacanvas, and the QT Canvas. Numerous canvas primitives are available, including arcs, rectangles, polylines, and line markers. An optional companion library, Papyrusmm, provides a set of Gtkmm widgets which includes viewports (a canvas display widget similar to Gtk::DrawingArea) and other UI widgets related to drawing interfaces.

0.13.2

This release features both bugfixes and enhancements. A bug causing segfaults in Drawable's destructor that removed a child from a parent was fixed. Fixing this bug allowed the base Papyrus::Object to inherit from sigc::trackable again. The Group::clear() method has been cleaned up and improved. This should result in a fairly significant performance improvement if you have many items in a group and regularly clear it. A simple estimate would put the old version at a performance level of 3 * O(n lg(n)) + O(n) and the new version at 4 * O(n).
