Adds a glow backdrop to the filtered Object.
Constructor
@:value({ quality : 1., gain : 1., radius : 1., alpha : 1., color : 0xFFFFFF })new(color:Int = 0xFFFFFF, alpha:Float = 1., radius:Float = 1., gain:Float = 1., quality:Float = 1.)

@: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(1)resolutionScale:Float = 1
Custom rendering resolution scaling of the filter.
Stacks with additional scaling from Filter.useResolutionScaling if enabled.
@:value(false)smooth:Bool = false
When enabled, filters on not Object which are not Drawable will use bilinear filtering when displayed and some filter will also use bilinear filtering on intermediate textures.
@:value(defaultUseScreenResolution)useScreenResolution:Bool = defaultUseScreenResolution
Use the screen resolution to upscale/downscale the filter rendering resolution.
Stacks with additional scaling from Filter.resolutionScale if enabled.

bind(s:Object):Void
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, scale:Point):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 are still applied, causing rendering area to shrink.
Parameters:
s | The Object instance to which the filter is applied. |
|---|---|
bounds | The Bounds instance which should be populated by the filter boundaries. |
scale | Contains the desired rendering resolution scaling which should be accounted when constructing the bounds. Can be edited to override provided scale values. |
