Crate geometrize 

Geometrize

Transform images into geometric art.

This crate provides two rendering styles:

• Low-poly: Decomposes an image into colored triangles via Delaunay triangulation.
• Pointillist: Renders the same triangulation as overlapping circles.

Quick Start

Images are transformed using the geometrize function.

use geometrize::{geometrize, Style, SamplingParams};
use image::{open, RgbaImage};

let image = open("launch.jpg").unwrap();
 
let lowpoly: RgbaImage = geometrize(
    &image,
    Style::Lowpoly,
    70_000,
    SamplingParams::default()
).unwrap();
lowpoly.save("lowpoly_70k.png").unwrap();

let pointillist: RgbaImage = geometrize(
    &image,
    Style::Pointillist {noise: 0.0},
    20_000,
    SamplingParams::default()
).unwrap();
pointillist.save("pointillist_20k.png").unwrap();

Transparent images

This also works with transparent images.

let image = open("dice.png").unwrap();
 
let lowpoly: RgbaImage = geometrize(
    &image,
    Style::Lowpoly,
    50_000,
    SamplingParams::default()
).unwrap();
lowpoly.save("lowpoly_50k_dice.png").unwrap();

let pointillist: RgbaImage = geometrize(
    &image,
    Style::Pointillist {noise: 0.0},
    10_000,
    SamplingParams::default()
).unwrap();
pointillist.save("pointillist_10k_dice.png").unwrap();

Parameters controlling how sample points are chosen from the image.

Enums

EdgePoints

Controls how many sample points are placed along the image border.

GeometrizeError

Error type for geometrize.

SampleSeed

Source of randomness for point sampling.

Style

The visual style used to render the output image.

Functions

geometrize

Convert an image into geometric art.

seed_from_image
