Visualize Stroke Region and Center of Gravity (COG)

Source: R/draw_stroke.r
draw_stroke.Rd

Visualizes the stroke region of a character-like binary image using the result from cog_stroke(). Optionally overlays crosshair lines at the computed center of gravity (COG) position.

Usage

draw_stroke(lst, show_cog = TRUE, plot_image = TRUE)

Arguments

lst

A list returned by cog_stroke, containing stroke pixel data and computed statistics.

show_cog

Logical. If TRUE (default), draws horizontal and vertical red lines through the COG to visualize its position.

plot_image

Logical. If TRUE (default), plots the image. If FALSE, returns the image object without plotting.

Value

An object of class cimg representing the stroke image (with or without COG lines), suitable for plotting or further manipulation.
