20.1.2.3.3 alphaOff (Alpha Offset)

This element specifies a more or less opaque version of its input color. Increases or decreases the input alpha percentage by the specified percentage offset. A 10% alpha offset increases a 50% opacity to 60%. A -10% alpha offset decreases a 50% opacity to 40%. The transformed alpha values are limited to a range of 0 to 100%. A 10% alpha offset increase to a 100% opaque object still results in 100% opacity.

<a:solidFill>
<a:srgbClr val="00FF00">
<a:alphaOff val="-10.000%"/>
</a:srgbClr>
</a:solidFill>

end example]
