These are links to the slides for talks I have done in the past.
Dutch PHP Conference 2010
- Graphics with Cairo — This is a very quick introduction to the basic APIs used in the PECL/Cairo extension.
- Building on Cairo — This is a lightning talk I gave on the Uncon track showing some extensions to Cairo I have been working on, for Pango and RSVG.
- Modern PHP Graphics with Cairo— Another introduction to the PECL/Cairo extension and what it can be used for.
- Making Software See — A general talk introducing some of the basic concepts of OpenCV, with examples in several languages.
