zebrash

Library for rendering ZPL (Zebra Programming Language) files as raster images

• Partially based on https://github.com/BinaryKits/BinaryKits.Zpl
• Uses slightly modified implementation of PDF417 barcode from https://github.com/boombuler/barcode/

Usage:

	file, err := os.ReadFile("./testdata/label.zpl")
	if err != nil {
		t.Fatal(err)
	}

	parser := zebrash.NewParser()

	res, err := parser.Parse(file)
	if err != nil {
		t.Fatal(err)
	}

	var buff bytes.Buffer

	drawer := zebrash.NewDrawer()

	err = drawer.DrawLabelAsPng(res[0], &buff, drawers.DrawerOptions{})
	if err != nil {
		t.Fatal(err)
	}

	err = os.WriteFile("./testdata/label.png", buff.Bytes(), 0744)
	if err != nil {
		t.Fatal(err)
	}
