## go-fitz

### Maal Disclaimer
This is just fork from github repository. Forked in order to recompile with new glibc version.

Whenever you have problem with compability you can download source package from [Mupdf source](https://mupdf.com/downloads/archive/mupdf-1.23.0-source.tar.gz) after simply run ``` make``` to compile on your platform. When this is completed just simply copy following files:

- ``` libmupdf.a```  ==> ```libs/libmupdfthird_linux_amd64.a```
- ```libmupdf-third.a```  ==> ```libs/libmupdf_linux_amd64.a```

Part of file name 'linux_amd64' maens OS and platform. 

### Musl Compilation
To compile for linux musl you can use docker and just simply run following command from CLI
- ```docker run --rm -v ./:/mupdf -it alpine:latest sh -c "apk update; apk add alpine-sdk; cd /mupdf;apk add freeglut-dev libxrandr-dev; make clean ;make; chown -R 1000:1000 ./build; mkdir ./musl; cp ./build/release/libmupdf.a ./musl/libmupdf_linux_amd64_musl.a; cp ./build/release/libmupdf-third.a ./musl/libmupdfthird_linux_amd64_musl.a"``` 

##### Notice that you need to compile MuPdf source for OS and platform you want to use

### ---------------------------------------------------------------------------------------

Go wrapper for [MuPDF](http://mupdf.com/) fitz library that can extract pages from PDF and EPUB documents as images, text, html or svg.

### Build tags

* `extlib` - use external MuPDF library
* `static` - build with static external MuPDF library (used with `extlib`)
* `pkgconfig` - enable pkg-config (used with `extlib`)
* `musl` - use musl compiled library
    
### Example
```go
package main

import (
	"fmt"
	"image/jpeg"
	"os"
	"path/filepath"

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

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