"filter" and "backdrop-filter" properties of View

The "filter" property (Filter constant) applies graphical effects to the View, such as blurring, color shifting, changing brightness/contrast, etc.The "backdrop-filter" property (BackdropFilter constant) applies the same effects but to the area behind a View.

Only the ViewFilter interface is used as the value of the "filter" properties.ViewFilter is created using the function

func NewViewFilter(params Params) ViewFilter

The argument lists the effects to apply. The following effects are possible:

Example

rui.Set(view, "subview", rui.Filter, rui.NewFilter(rui.Params{rui.Brightness: 200,rui.Contrast: 150,}))

You can get the value of the current filter using functions

func GetFilter(view View, subviewID ...string) ViewFilter
func GetBackdropFilter(view View, subviewID ...string) ViewFilter
