Add capture area to surface plot

Adds the capture area as a rectangular and/or crops the frame of the plot accordingly.

ggpLayerCaptureArea(
  object,
  opt = c("rect"),
  rect_alpha = 0.9,
  rect_clr = "black",
  rect_line_type = "solid",
  rect_size = 1,
  expand_rect = 0.025,
  expand_x = ggplot2::waiver(),
  expand_y = ggplot2::waiver(),
  img_name = activeImage(object)
)

Arguments

object

An object of class SPATA2 or, in case of S4 generics, objects of classes for which a method has been defined.

opt

Combination of 'rect' and/or 'crop'.

rect_alpha

The alpha transparency level of the rectangle's border

expand_x, expand_y

Given to expand of ggplot2::scale_x/y_continuous().

img_name

Character value. The name of the image of interest. If NULL, the active image is chosen by default. Either way, must be one of getImageNames().
