resvg-go

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

Usage

Render by default

// 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

// 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()
