# wmap-renderer
A rust renderer for `wmap` formatted wardley maps parsed with [`wmap-parser`][wmap-parser-rust].
## Features
- Can render to PNG or SVG.
- Rendering logic attempts to replicate [map][map]'s output.
## Installation
Add it to your project with cargo add
```bash
cargo add wmap-renderer
```
## Usage
```rust
use wmap_renderer::{render_to_png, render_to_svg, Configuration, StageType};
let map_source = r#"
Computer (90, 20)
Silicon Ore (80, 90)
Computer -> Silicon Ore
"#;
let map = wmap_parser::parse(map_source);
let config = Configuration::default();
// Render to PNG
let png_data = render_to_png(&map, StageType::Activities, &config)?;
std::fs::write("map.png", png_data)?;
// Render to SVG
let svg_data = render_to_svg(&map, StageType::Activities, &config)?;
std::fs::write("map.svg", svg_data)?;
```
## Configuration
The renderer lets you configure sizes, colors, and font.
```rust
let mut config = Configuration::default();
config.theme.colors.vertex = "#FF0000".to_string();
config.theme.sizes.vertex_size = 30.0;
config.options.show_background = false;
```
## Development
### Running Examples
```bash
make examples
```
### Running Tests
```bash
make test
```
## Performance
The drawing is not optimized for live-editing. It's relatively quick to
generate a single image. On an M1 Pro mac, our xample map renders in about ~2ms,
while a larger map with slightly under 2000 entities does so in ~140ms.
Turning off smart labels doesn't have a big effect on medium to small maps,
but in our large map test it renders in ~97ms instead.
You can run the benchmarks by using:
```bash
make benchmark
```
