Provides a solid color outline to the filtered object by utilizing h3d.pass.Outline render pass.


@:value({ multiplyAlpha : true, quality : 0.3, color : 0x000000, size : 4.0 })new(size:Float = 4.0, color:Int = 0x000000, quality:Float = 0.3, multiplyAlpha:Bool = true)

Create a new Outline filter.



Width of the outline.


The color of the outline.


The sample count with quality/speed tradeoff.


Enable alpha premultiplying of the resulting color.



The transparency of the outline.


The color of the outline.

Premultiplies the resulting color with its alpha when enabled.

Represents sample count with quality/speed tradeoff. Larger value leads to more samples and more accurate outline in exchange to calculation speed.

Inherited Variables

Defined by Filter

@:value(true)autoBounds:Bool = true

When enabled, rendering bounds of the filter will be expanded by Filter.boundsExtend in all directions. Otherwise filter should provide custom bounds through Filter.getBounds call.
Default : true.

@:value(0.)boundsExtend:Float = 0.

Rendering texture boundaries extent. Increases the rendering area by twice the Filter.boundsExtend value.
Automatically applied to object bounds when autoBounds = true or Filter.getBounds is not overridden.
Does not affect boundaries when autoBounds = true and boundsExtend is less than 0.

@:value(true)@:isVarenable:Bool = true

When filter is disabled, attached object will render as usual.

@:value(false)smooth:Bool = false

When enabled, some filters will use bilinear filtering on temporary textures.
Does not affect the majority of filters.

Inherited Methods

Defined by Filter


Sent when filter is bound to an Object s. If Object was not yet allocated, method will be called when it's added to allocated Scene.

getBounds(s:Object, bounds:Bounds):Void

Method should populate bounds with rendering boundaries of the Filter for Object s. Initial bounds contents are undefined and it's recommended to either clear them or call s.getBounds(s, bounds). Only used when Filter.autoBounds is false. By default uses given Object bounds and extends them with Filter.boundsExtend. Compared to autoBounds = true, negative boundsExtend is still applied, causing rendering area to shrink.


Sent when filter was unbound from an Object s. Method won't be called if Object was not yet allocated.
