  A SVG renderer written in Go & WASM depended on resvg without CGO



  



## Usage

### Render by default

```go

// initialize and don't forget to close!

// worker are not goroutine-safe!

worker, _ := NewDefaultWorker(context.Background())

defer worker.Close()

// render the SVG as a PNG!

png, _ := worker.Render(svg)

```

### Render with options

```go

// initialize and don't forget to close!

// worker are not goroutine-safe!

worker, _ := NewDefaultWorker(context.Background())

defer worker.Close()

// render the SVG as a PNG!

fontdb, _ := worker.NewFontDBDefault()

defer fontdb.Close()

fontdb.LoadFontData(ttf)

pixmap, _ := worker.NewPixmap(512, 512)

defer pixmap.Close()

tree, _ := worker.NewTreeFromData(svg, &Options{})

defer tree.Close()

tree.ConvertText(fontdb)

tree.Render(TransformIdentity(), pixmap)

png, _ := pixmap.EncodePNG()

```
