C# Class SparrowSharp.Filters.BlurFilter

The BlurFilter applies a gaussian blur to an object. The strength of the blur can be set for x- and y-axis separately (always relative to the stage).

A blur filter can also be set up as a drop shadow or glow filter. Use FilterFactory to create such a filter.

For each blur direction, the number of required passes is ceil(blur).

blur = 0.5: 1 pass

blur = 1.0: 1 pass

blur = 1.5: 2 passes

blur = 2.0: 2 passes

etc.

Méthode	Description
BlurFilter ( float blur = 1.0f, float resolution = 1.0f ) : System	Initializes a blur filter with the specified blur and a resolution.
SetUniformColor ( bool enable, uint color = 0x000000, float alpha = 1.0f ) : void	A uniform color will replace the RGB values of the input color, while the alpha value will be multiplied with the given factor. Pass false as the first parameter to deactivate the uniform color.
