+
+### Build tags
+
+* `extlib` - use external MuPDF library
+* `static` - build with static external MuPDF library (used with `extlib`)
+* `nopie` - use this with GCC older then 7
+    
+### Example
+```go
+package main
+
+import (
+	"fmt"
+	"image/jpeg"
+	"io/ioutil"
+	"os"
+	"path/filepath"
+
+	"github.com/karmdip-mi/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 {
+			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()
+	}
+
+	// Extract pages as text
+	for n := 0; n < doc.NumPage(); n++ {
+		text, err := doc.Text(n)
+		if err != nil {
+			panic(err)
+		}
+
+		f, err := os.Create(filepath.Join(tmpDir, fmt.Sprintf("test%03d.txt", n)))

+
+		_, err = f.WriteString(text)
+		if err != nil {
+			panic(err)
+		}
+
+		f.Close()
+	}
+
+	// Extract pages as html
+	for n := 0; n < doc.NumPage(); n++ {
+		html, err := doc.HTML(n, true)
+		if err != nil {
+			panic(err)
+		}
+
+		f, err := os.Create(filepath.Join(tmpDir, fmt.Sprintf("test%03d.html", n)))

+			panic(err)
+		}
+
