R: Render Boolean Distance

render_boolean_distance {rayimage} | R Documentation

## Render Boolean Distance

### Description

Takes an matrix (or and returns the nearest distance to each TRUE.

### Usage

    render_boolean_distance(boolean, rescale = FALSE)

### Arguments

`boolean` | Logical matrix (or matrix of 1s and 0s), where distance will be measured to the `TRUE` values.
`rescale` | Default `FALSE`. Rescales the calculated distance to a range of 0-1. Useful for visualizing the distance matrix.

### Value

Matrix of distance values.

### Examples

    if(interactive()){
    #Measure distance to
    image(render_boolean_distance(volcano > 150))
    image(render_boolean_distance(volcano < 150))

    #If we want to rescale this to zero to one (to visualize like an image), set rescale=TRUE
    plot_image(render_boolean_distance(volcano > 150,rescale=TRUE))
    }
