agg

A Rust port of Anti-Grain Geometry

A High Fidelity and Quality 2D Graphics Rendering Engine

Usage

Add this to your Cargo.toml:

[dependencies]
agg = "0.1.0"

Example

Little Black Triangle

use agg::PixelData;
use agg::Render;

// Create a blank image 10x10 pixels
let pix = agg::Pixfmt::<agg::Rgb8>::new(100,100);
let mut ren_base = agg::RenderingBase::new(pix);
ren_base.clear(agg::Rgba8::white());

// Draw a polygon from (10,10) - (50,90) - (90,10)
let mut ras = agg::RasterizerScanline::new();
ras.move_to_d(10.0, 10.0);
ras.line_to_d(50.0, 90.0);
ras.line_to_d(90.0, 10.0);

// Render the line to the image
let mut ren = agg::RenderingScanlineAASolid::with_base(&mut ren_base);
ren.color(&agg::Rgba8::black());
agg::render_scanlines(&mut ras, &mut ren);

// Save the image to a file
agg::ppm::write_ppm(&ren_base.pixeldata(), 100,100,
                    "little_black_triangle.ppm").unwrap();

Features

  • Anti-Aliased Drawing

  • Sub-pixel Accuracy

  • Rendering of Arbitrary Polygons

  • Text/Font Rendering (through with Freetype)

  • Performance ? (to be determined)

Complexity

Quoting the original C++ library:

Anti-Grain Geometry is not a solid graphic library and it's not very easy to use. I consider AGG as a "tool to create other tools". It means that there's no "Graphics" object or something like that, instead, AGG consists of a number of loosely coupled algorithms that can be used together or separately. All of them have well defined interfaces and absolute minimum of implicit or explicit dependencies.
