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.

JavaScript Usage

If you are working in JavaScript, check out geometrizejs which provides JavaScript API and types for this library, tested on browser and Node.js.

On top of it, geometrizejs-cli tool provides command line interface and support for common image formats.

Haxe Install

Get the Haxe library from GitHub or through haxelib:

haxelib install geometrize-haxe

Haxe 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.
