### 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.

|
|
* `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"
|

|
|
"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)
|

}
