Draw Circles on an Image — drawCircle • Rvision

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

drawCircle(image, x, y, radius, color = "red", thickness = 1)

Arguments

image	An `Image` object.
x	A numeric value or vector representing the x coordinates of the centers of each circle.
y	A numeric value or vector representing the y coordinates of the centers of each circle.
radius	A numeric value or vector representing the radii of each circle.
color	A value or vector of any kind of R color specification compatible with `col2rgb` representing the color of each circle's outline (default: "red").
thickness	A numeric value or vector representing the thickness in pixels of each circle's outline (default: 1). If negative, then a filled rectangle is drawn.

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