TIEPenOptions.OpacityEnabled

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.

Notes:
- 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

Value Description
enFalse Pen pressure has no effect on brush opacity
enTrue Pen pressure affects brush opacity
enAuto Pen pressure affects brush opacity when the Ctrl key is pressed

Default: enTrue


Examples

ImageEnView1.BrushTool.PenEffects.OpacityEnabled := enAuto;

// Pressure of pen has no effect on brush opacity
