When blitting surfaces or drawing primitives in EDGELIB-driven applications, a variety of powerful color filters can be applied for special effects. Also all combinations of color filters can be used.
Currently EDGELIB supports the following color filters:
- Color key
- Opacity blending
- Additive alpha blending
- Subtractive alpha blending
- Color fill
In the next sample images an additional color key filter (black) is added, except for the first one.
Use pixel shaders to create custom effects on a per-pixel basis.
