drawRectangle draws rectangles over an Image
object. This operation is destructive: it changes irreversibly the
Image object and cannot be undone.
drawRectangle(image, pt1_x, pt1_y, pt2_x, pt2_y, color = "red",
thickness = 1)| image | An |
|---|---|
| pt1_x | A numeric value or vector representing the x coordinates of a corner of each rectangle. |
| pt1_y | A numeric value or vector representing the y coordinates of a corner of each rectangle. |
| pt2_x | A numeric value or vector representing the x coordinates of the corners opposite to pt1. |
| pt2_y | A numeric value or vector representing the y coordinates of the corners opposite to pt1. |
| color | A value or vector of any kind of R color specification compatible
with |
| thickness | A numeric value or vector representing the thickness in pixels of each rectangle's outline (default: 1). If negative, then a filled rectangle is drawn. |
This function does not return anything. It modifies image in
place.
