This will make things much easier in the future. And that's it. Definitely don't give up. Being able to use libpng will be an important advantage in the future, and not only for this column. This week you learned how to create effects with filters.
Filters are a quite simple way to create good looking effects.
Once again, all you need is a bit of imagination to create good filters. We also learned why the use of filters should be avoided if possible, since the output is frame rate dependent. By checking the source, you will also learn how to use libpng to read PNG files. Next week, we will learn about bitmap distortion, and bilinear filtering.
