Draw Lines on an Image

drawLine draws lines over an Image object. This operation is destructive: it changes irreversibly the Image object and cannot be undone.

drawLine(image, pt1_x, pt1_y, pt2_x, pt2_y, color = "red",
  thickness = 1)

Arguments

image	An Image object.
pt1_x	A numeric value or vector representing the x coordinates of the first end of each line.
pt1_y	A numeric value or vector representing the y coordinates of the first end of each line.
pt2_x	A numeric value or vector representing the x coordinates of the second end of each line.
pt2_y	A numeric value or vector representing the y coordinates of the second end of each line.
color	A value or vector of any kind of R color specification compatible with col2rgb representing the color of each line (default: "red").
thickness	A numeric value or vector representing the thickness in pixels of each line (default: 1).

Value

This function does not return anything. It modifies image in place.
