tdewolff/minify sample using reader and writer

main.go

package main

import (
	"bufio"
	"log"
	"os"

	"github.com/tdewolff/minify"
	"github.com/tdewolff/minify/svg"
)

func minifySVG(svgFile string) error {
	mediaType := "image/svg+xml"
	m := minify.New()
	m.AddFunc(mediaType, svg.Minify)

	f, err := os.Open(svgFile)
	if err != nil {
		return err
	}
	defer f.Close()

	f2, err := os.Create("/tmp/dest.svg")
	if err != nil {
		return err
	}
	defer f2.Close()

	w := bufio.NewWriter(f2)
	r := bufio.NewReader(f)
	if err := m.Minify(mediaType, w, r); err != nil {
		return err
	}

	return nil
}

func main() {
	err := minifySVG("/tmp/org.svg")
	log.Println(err)
}

It seems tdewolff/minify doesn't work with svg file as expected.
