EffectSparkler generates multi colored flashing flowers around a thin pencil like object known as the Firework Sparkler. The sparkler burns from start to end during the range of the effect. In stead of color, white can be opted as color of flowers. The outward radial distance of travel of the beams till they burst out as flowers (radius) can be specified. Repeating this effect with a slight offset in frame numbers keeping rest of parameters (excepting may be color) same gives a good realistic effect. 4 sec or longer effect will look good. RGB32, RGB24 YUY2 and YV12 only are supported at this time.
