	"github.com/gen2brain/go-fitz"
)

func main() {
	doc, err := fitz.New("test.pdf")
	if err != nil {
		panic(err)
	}

	defer doc.Close()

	tmpDir, err := ioutil.TempDir(os.TempDir(), "fitz")
	if err != nil {
		panic(err)
	}

	// Extract pages as images
	for n := 0; n < doc.NumPage(); n++ {
		img, err := doc.Image(n)
		if err != nil {

		f, err := os.Create(filepath.Join(tmpDir, fmt.Sprintf("test%03d.jpg", n)))
