Transparency Thresholds

The transparency thresholds attribute defines the thresholds used by transparency method PEXMultipassRendering. The transparency method is also a renderer attribute. In the first pass, all pixels with alpha values greater or equal to the first threshold are rendered. In the ith pass, where i is in the range [2..n], all pixels with alpha values less than the (i-1)th threshold value and greater than or equal to the ith threshold value are rendered. In the (n+1)th pass, all pixels with alpha values less than the nth threshold and greater than or equal to 0.0 are rendered. There are n+1 passes for n threshold values.

The complete list of renderer attributes is listed in the Renderer Attributes Table.
