Overview

This chapter demonstrates how to use the SVG filter element (which contains one or more filter primitives) in order to create a variety of filter effects. After you've finished this chapter, you'll have an appreciation for the rich textural patterns that can be created in SVG. This is another area where SVG positively shines and towers above the traditional programming languages. You will see examples of some of the SVG filter primitives (a complete list appears near the end of the chapter) combined with other SVG elements to render an interesting set of graphics images.

As an ancillary note, you need to be aware of the fact that the learning curve for this topic can be significant. While many of the features (e.g., rotate, translate, skew) of SVG are easy to use after you've seen an example of how to use them, a lot of the SVG filters are not intuitively obvious. As you delve into SVG filters, you'll see that some of them are extremely powerful and sophisticated, but sometimes it's not apparent where they would prove useful; that is, there is no a priori way of knowing how to generate interesting graphics images with every filter. This knowledge can only be acquired through practice and experimentation. All code and images for this chapter can be found on the companion CD-ROM in the Chapter 7 folder.
