Since some of us are perhaps afraid to dive inside the 'Dev' section, I'm posting here a quick summary of a behavior I've made : ImageEffects and TextOnSprite.
You can find the original thread here : http://www.scirra.com/forum/behavior-sprite-effects-inject-text-on-sprite_topic51516_post324649.html#324649
With that behavior attached to a Sprite, you can apply Image Effects to the image of the Sprite, and keep the effect.
On "small" images, it works fast : https://dl.dropbox.com/u/1412774/NewEffectsDemo6/index.html (although, for the sake of your CPU, I wouldn't use it on all ticks... <img src="smileys/smiley2.gif" border="0" align="middle">).
Here's the .capx of that demo, to see how it's done : https://dl.dropbox.com/u/1412774/NewEffectsDemo6/NewEffectsDemo6.capx (here's the behavior : https://dl.dropbox.com/u/1412774/NewEffectsDemo6/pode_textOnImageAndImageEffects.1.8.zip. Don't forget to put it inside the behavior folder !).
Some of the effects :
- save the image (to remove the effects...)
- pixelate :

- change RGB value (with tolerance) :

- grayscale, edges, color tint (with white pixel respect or not), noise, rotate color channels (on the left or on the right side), emboss, sharpen, sepia, RGB2BGR, negative (with white pixel respected or not)
