filterSurfaceBlur property
final
filterBlur
parameters default to _MINIMUM_BLUR
== 0.0000001
so that
upper-layered filters are not erased by an ancestor filter having 0 radius.
- If filterStyle is set to enable all three filters, by SurfaceFilter.TRILAYER,
set all three
filterBlur
params>= 0.01
. - Similarly, if only two filters are enabled by, say SurfaceFilter.SURFACE_AND_CHILD, the lower filter (filterSurfaceBlur in this case) must be above zero to not negate any value passed to the higher filter (filterChildBlur in this case).
Implementation
final double filterSurfaceBlur, filterMaterialBlur, filterChildBlur;
