TIEPenOptions.OpacityEnabled
Declaration
property OpacityEnabled: TIEEnabled;
Description
When enabled, pen pressure will affect the opacity, i.e. minimal pressure draws with maximum transparency, whereas more pressure draws with minimum transparency.
If
OpacityEnabled is enAuto, then holding down the Ctrl key will enable it.
Note:
◼OpacityEnabled works in tandem with
Transparency, e.g. if
Transparency is 128 (50% opacity) then with full pen pressure, painting will never exceed 50% opacity.
◼The strength of pressure on transparency is controlled by
OpacityStrength◼When using a
Retouch Tool, this option only has effect when using iermSmudge. It controls the
strength of the effect
