drawCircle: Draw Circles on an 'Image'

In neuroconductor-releases/Rvision: Basic Computer Vision Library

Description

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

Usage

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.

Value

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