How do I export to gif?

[mark-summerfield]

I have this function which works:

func SvgForD2(text string) ([]byte, error) {
	ruler, _ := textmeasure.NewRuler()
	layoutResolver := func(engine string) (d2graph.LayoutGraph, error) {
		return d2dagrelayout.DefaultLayout, nil
	}
	renderOpts := &d2svg.RenderOpts{
		Pad:     go2.Pointer(int64(5)),
		ThemeID: &d2themescatalog.GrapeSoda.ID,
	}
	compileOpts := &d2lib.CompileOptions{
		LayoutResolver: layoutResolver,
		Ruler:          ruler,
	}
	diagram, _, err := d2lib.Compile(context.Background(), text,
		compileOpts, renderOpts)
	if err != nil {
		return nil, err
	}
	svg, err := d2svg.Render(diagram, renderOpts)
	if err != nil {
		return nil, err
	}
	return svg, nil
}

where the input text is SVG.

I now want to create GifForD2(). The docs say that you can export to gif but I can't see how.

There's no top-level function right now.

You'll have to convert each SVG to PNG: https://github.com/terrastruct/d2/blob/master/lib/png/png.go#L91

And then pass in the PNGs to make the gif: https://github.com/terrastruct/d2/blob/master/lib/xgif/xgif.go#L31
