Slides and other materials for various presentations I've given. I try to give a couple a year, I think that it's important that we talk about what's we're working on developing in Open Source. Sure, you can publish the code but there is a lot more context that helps in understanding what it does and its implications. Generally speaking if I give a presentation twice I take the last time's slides and update them with what worked or didn't, so that's why I put multiple sets here. Please contact me if you think some of these topics would be good to present to a group or conference you're organizing.

SVG Filters provide a way to achieve effects on vector art that are commonly only associated with bitmap tools. By taking vector objects and doing bitmap operations on them artists can maintain the ability to edit the image while still get their desired effects. They give the artist the ability to control the vector rendering pipeline in powerful ways. Inkscape provides tools to build these filters from the basic building blocks in the SVG specification. There are also SVG Filters that are build into Inkscape that can be used to quickly adjust an work. Learning to use the built in filters, build your own filters and package those filters for other artists to use are all powerful ways of using Inkscape to create dramatic images.
