Problem displaying barcode using milon/barcode with domPDF

I'm having problem displaying barcode using milon/barcode with domPDF

If i try to output it in html with the following code it works properly.:

laravel controller file //where dataproduct is array of product.id, product.name and etc

    return view('produk.barcode',compact('dataproduct','no'));

html:

    <img src="data::image/png;base64,{{ DNS1D::getBarcodePNG($data->code_product,'C39') }}" height="60" width="180" /><br />

when I try to output it with dompdf with the following code, the barcode doesn't show up properly. it gives "image not found or type unknown" error message

laravel controller file //where dataproduct is array of product.id, product.name and etc

    $pdf = PDF::setOptions(['isHtml5ParserEnabled'=>true,'isRemoteEnabled'=>true])->loadView('product.barcode',compact('dataproduct','no'));
    $pdf->setPaper('a4', 'potrait');
    return $pdf->stream();

html:

    <img src="data::image/png;base64,{{ DNS1D::getBarcodePNG($data->code_product,'C39') }}" height="60" width="180" /><br />

it seems that dompdf can't display the png image i generated on fly. Can anyone help me with this problem?

thanks
