Barcode cod128 en picking

[David Hernández]

Hola, estoy mirando de introducir un codigo de barras en el picking list. 

He probado con el módulo

 Webkit Report Barcode de https://github.com/OCA/webkit-tools/tree/7.0/report_webkit_barcode

Segun la documentación para añadir el codigo debería poner algo así:

${helper.barcode(picking.name)} o ${helper.barcode(picking.name, code='EAN13', drawOpts=None, htmlAttrs=None)} , etc si quiero otro tipo de código, el caso es que con el por defecto, que es COD128, el reporte me sale con el código en bruto, es decir, no me le pinta correctamente, en concreto sale:

<img

src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAGYAAAASCAIAAAAmDjziAAAA5ElEQVR4nO3QIY6GMBCG4S8rMRhM&#10;z8ENMBgUpgZTU11Tg0HV1DQhJcWjMSg0h  .....

Alguno de vosotros se ha encontrado con el mismo problema?.

También he probado poner directamente la fuente cod128:

        @font-face

{

    font-family: barcode;

    src: url(/opt/odoo/custom/code128.ttf);

}

/* Use the new font in a css class */

.barcode-class

{

    font-family: barcode;

    font-size: 100px;

    padding:3px;

    margin-bottom: 10px;

}

y imprimirla como:

<div class="barcode-class">${picking.name or ''}</div>

pero el lector no reconoce el código

He intentado utilizar también  https://github.com/OCA/stock-logistics-barcode/tree/7.0/tr_barcode_on_picking  , pero directamente este módulo al validar la órden de venta ya me salta este error y no he podido probarlo:

Como hago para imprimir el cod128???  

Gracias.

Hola que tal, pudiste resolver el problema?... estoy en un caso similar....

[Dunkel Meister]

Bueno después buscarle un poco al código actualizo y comento como lo pude solucionar yo...
en la función barcode de helper_barcode.py del modulo Webkit Report Barcode

en lugar de devolver la etiqueta html, le dije que sólo devolviera la imagen ya decodificada a 'base64'

        data = createBarcodeDrawing(code, **drawOpts).asString(imgtype)
#        attrs['src'] = "data:image/{1};base64,{0}".format(
#            data.encode('base64'), imgtype,
#        )
#        return HTML(Element('img', attrs))        
        return data.encode('base64')

así en el reporte, primero recibo a una variable la imagen decodificada, y luego la agrego con helper.embed_image

    <% code_bar =helper.barcode(o.alpha_ref,drawOpts={'height':70,'width':300})%>
       ${helper.embed_image('jpg',code_bar)}

espero que a alguien que esté en un problema similar le sirva.
