Actionscript updating dynamic text

Medium quality means the same filter is applied twice; and high quality applies this filter 3 times.

It means the quality heavily affects the visual radius of the filter.

In Adobe Flash, filters are applied consecutively to the raster result of the entire text field.

This means that there can be Blur, Drop Shadow, and Glow filters applied one after another.

Because of different approaches, the visual result is different, but similar.

In fact, a simple one-pass box filter produces too poor a result.

Although Scaleform text filters work similar to Flash there are a number of differences.

Only “Low quality” differs from the others in Scaleform.

“Medium quality” and “High quality” generate identical results.

The Glow filter is actually a sub-set of the Drop Shadow filter.

Unlike Flash the filters are not applied consecutively, instead, they work independently, as two different layers.
