Opacity

From xat wiki
Example of (d) smiley at 50% opacity.

Opacity is a function power that allows you to change the opacity of your smilies.

To use this power, add #opacity#w5-100 to your smiley code.

Any value from 5 through 100 can be used, which represents the percentage of opacity, for example #w50 would make the smiley only 50% visible.
