Description

Add a grid of lines to overlay the surface of an x3p object. Lines are added to a mask. In case no mask exists, one is created.

Usage

x3p_add_grid(
  x3p,
  spaces,

  color = c("grey50", "black", "darkred")
)

## Not run: 
logo <- x3p_read(system.file("csafe-logo.x3p", package = "x3ptools"))
# ten vertical lines across:
logoplus <- x3p_add_grid(logo,
  spaces = 50e-6, size = c(1, 3, 5),
  color = c("grey50", "black", "darkred")
)
x3p_image(logoplus, size = c(741, 419), zoom = 0.5)
