This project contains a processing sketch for creating a stippling version of an input image by applying Weighted Voronoi Stippling. An example:

Usage

To be added :)

Parameters

Parameters for image:

• input_name: relative path to your image
• canvas_w: width of your image
• canvas_h: height of your image

Paramters for stippling

• N: number of seed points
• thresh: treshold to place initial seed points -> lower thresh means initial points will be more clustered in the darkest areas
• max_iter: maximum number of relaxation iterations

Parameters for debugging:

• show_paths: flag for showing paths the seed points make in their relaxation
• show_diagrams: flag for showing the voronoi diagrams used to relax the seed points
• preview_only: flag for preventing relaxation, only shows the initial seed points
• print_logs: flag for printing messages at each function call
• show_imgs: flag for showing the input image under the stippling

Parameters for plotting:

• save_hpgl: flag for generating and saving the relaxed stipples
• output_name: relative path to the output file (will create a new file if file is not found, or overwrite an existing file)
• scale_offset: the offset to the scaling: the short side of the paper will be max(canvas_w, canvas_h) + offset
• plot_w: currently unused -- might be used for plotter coordinates
• plot_h: currently unused -- might be used for plotter coordinates
• plot_offset_x: currently unused -- might be used for offsetting the output relative to a different starting point
• plot_offset_y: currently unused -- might be used for offsetting the output relative to a different starting point
