I have a gallery filled with photos. The photos are loaded
into Sprites and I need to desaturate them. When a Sprite is
clicked, its image should return to its original saturation value
in a tweened effect. I managed to achieve a desaturated effect
using the ColorMatrixFilter, but mostly through experimenting with
different values, not the most scientific approach. So:
1 - Is there a better way to change an image's saturation? Or
can anyone explain me how to change the ColorMatrixFilter's values
to get a certain amount of saturation?
2 - How can I switch between the saturated/desaturated values
with a tween-like effect?
