but header('content-type: image/png') not displaying image small icon.

your code should working follows examples user guide.

why trying print $drawing? open page in browser , should see generated barcode. explain

if have specified filename before, image saved file, otherwise displayed.

so, if want saved somewhere, add filename when needed.

$drawing = new bcgdrawing('/route/to/your/file.png', $colorback);
