Extruded text

- In the next example found in chapter four…under extruded text I want to show you…the power of the feConvolveMatrix filter…to create things like bevels.…So what I have here right now is a text…superimposed on top of an image.…I want to make it look like this text is popping out…and I want to create an angled bevel behind it.…To do that I need to do a whole bunch…of different filter alogorithims…'cause I also want to add a stroke around it…and make it all nice and fancy.…So inside the filter with the ID extrudeText,…if you scroll all the way to the bottom…you'll see here we have a feMerge filter primitive…that is currently just bringing in the source graphic.…

As we add in more elements…we'll keep adding them in down here.…So, to start off we're gonna do two things.…First, we're gonna flood the entire text area with white…then we're gonna us feMorphology to dilate the text…and create a radius of six around everything…to send that into the stroke keyword…and finally we'll use feComposite…to composite this new stroke on top of the white color…
