with_interpolate

Blend two layerrs together by averaging them out

Description

Two layers can be blended together in the literal sense (not like with_blend()) so that the result is the average of the two. This is the purpose of with_interpolate().

Usage

with_interpolate(x, bg_layer, src_percent, bg_percent = 100 - src_percent, ...)

Arguments

`x`	A ggplot2 layer object, a ggplot, a grob, or a character string naming a filter
`bg_layer`	The layer to blend with
`src_percent, bg_percent`	The contribution of this layer and the background layer to the result. Should be between 0 and 100
`...`	Arguments to be passed on to methods. See the documentation of supported object for a description of object specific arguments.

Value

Depending on the input, either a grob, Layer, list of Layers, guide, or element object. Assume the output can be used in the same context as the input.

Examples

library(ggplot2)
ggplot(mpg, aes(class, hwy)) +
  as_reference(geom_boxplot(), 'box') +
  with_interpolate(geom_point(), bg_layer = 'box', src_percent = 70)
