Geometrize Haxe is a Haxe library for recreating images with geometric primitives. Run the demo in your browser.

Geometrize Haxe is part of Geometrize, and is based on the primitive Go library.

Features

• Recreate images as geometric primitives - rectangles, rotated rectangles, triangles, circles, ellipses, rotated ellipses and lines are supported.
• Export generated shape data to JSON.
• Export geometrized images as SVGs.
• All Haxe targets are supported.

Shape Comparison

The matrix shows typical results for circles, triangles, rotated rectangles, rotated ellipses and all supported shapes at 50, 200 and 500 total shapes:

-	50 Shapes	200 Shapes	500 Shapes
Circles
Triangles
Rotated Rectangles
Rotated Ellipses
All Shapes

How It Works

A user provides a target image, and the algorithm finds shapes to approximate that image. To identify a good shape, the algorithm generates a large number of random candidate shapes, repeatedly improving the fit of each using a hillclimbing optimization approach, eventually choosing the best-fitting shape. The shapes are added one by one.

Install

Get the Haxe library from GitHub or through haxelib.

Usage

• Instantiate an `ImageRunner, passing it a Bitmap target image and a starting background Rgba` color.
• Generate shapes by repeatedly calling `runner.step(options), passing in your ImageRunnerOptions`.
• Export the results using the `export methods on SvgExporter and ShapeJsonExporter`.

Refer to the library documentation. Also see the Geometrize Haxe web demo and code, or this HaxeFlixel example and code.

Notes

• This implementation is single-threaded, and performance varies by target platform. Small target images work best.
