/* gtkcairo - GTK+ widget for displaying a Cairo surface. * * Hacked up by Evan Martin <martine@danga.com>. * further modified by OEyvind Kolaas <oeyvindk@hig.no> */ GtkCairo is a library that provides a new widget to be used in your GTK+ program: a Cairo surface. Dependencies ------------ GtkCairo depends on the obvious two: - GTK 2: http://www.gtk.org - Cairo: http://www.cairographics.org Usage ----- Hook up to the widgets "paint" signal with your custom drawing code, queue redraw of the widget using gtk_widget_queue_draw (widget); The interesting bits are the operations you can perform on the Cairo surface, the documentation of which is outside the scope of GtkCairo. To use GtkCairo in your code, add the package "gtkcairo" to the list of packages you pull in via pkg-config. Backend selection ----------------- GtkCairo should choose a reasonable cairo backend by default, at the moment this means the xlib backend since it provides AA at all times, setting the backend can be done through the enviroment variable export GTKCAIRO_BACKEND = gl export GTKCAIRO_BACKEND = xlib export GTKCAIRO_BACKEND = image before starting an application. Acknowledgement --------------- The majority of GtkCairo was a cut'n'paste job from from grrobot, by Carl Worth. vim: tw=70
