Set the ggblanket fill blend function

When polygon = TRUE, fill_blend is a function applied to the colour and colour_palette to derive the fill. Only one of the colour blend and fill blend can be active: setting a non-NULL fill blend clears any colour blend (last call wins), and the colour blend then defaults to identity.

Usage

set_fill_blend(new = NULL)

Arguments

new

A function of one argument (a colour vector), e.g. \(x) scales::alpha(x, 0.75). NULL (default) resets to the default of identity.

Value

Invisibly, the previous value of the option.

Examples

set_fill_blend(\(x) scales::alpha(x, 0.75))
