agg

A Rust port of Anti-Grain Geometry

A High Fidelity and Quality 2D Graphics Rendering Engine

Usage

Add this to your Cargo.toml:

toml [dependencies] agg = "0.1.0"

Example

```rust use agg::PixelData; use agg::Render;

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

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

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

// Save the image to a file agg::ppm::writeppm(&renbase.pixeldata(), 100,100, "littleblacktriangle.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.
