Turn text into the points that draw it

This function draws the text on a temporary bitmap and returns the position of every pixel the text covers. These are the points that surreal_text() hides. Getting them first lets you look at them, change them, or combine them with other points before handing them to surreal().

Usage

surreal_text_points(text = "hello world", cex = 4)

Arguments

text

Character. A plain text message to be plotted. Default is "hello world".

cex

Numeric. A value specifying the relative size of the text. Default is 4.

Value

A data.frame with one row for each point of the text and two columns, x and y.

See also

surreal_text() to go from text to a dataset in one step. surreal_image_points() for the points of an image.

Examples

# The points that draw "R is fun"
points <- surreal_text_points("R is fun")
plot(points, pch = 16, asp = 1)


# Hide them in a dataset, as surreal_text() does
result <- surreal(points)
