    if err != nil {
        panic(err)
    }

    defer doc.Close()

    tmpDir, err := os.MkdirTemp(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 {
            panic(err)
        }

        f, err := os.Create(filepath.Join(tmpDir, fmt.Sprintf("test%03d.jpg", n)))
        if err != nil {
            panic(err)
        }

        err = jpeg.Encode(f, img, &jpeg.Options{jpeg.DefaultQuality})
        if err != nil {
            panic(err)
        }

        f.Close()
