How to get nice EAN13 and EAN14? #292

Closed moreplavec closed 3 years ago

moreplavec commented 3 years ago

I see nice examples, but each time i try to generate EAN13 or EAN14 i get something very strange. I tried to get bigger resolution and font, but no luck to get simething nice i see everywhere. Please, can you send me options you use to generate EANs?

ean13_barcode = treepoem.generate_barcode(barcode_type='ean13', data=ean13_gen, options={'guardwhitespace': True, 'includetext': True, 'textsize': '19', 'height': '3', 'width': '5'})

generates: https://ibb.co/3C2Y513

ean13_barcode = treepoem.generate_barcode(barcode_type='ean13', data=ean13_gen, options={'includetext': True, 'height': '3', 'width': '5'})

generates: https://ibb.co/y8yt8Z4

ean14_barcode = treepoem.generate_barcode(barcode_type='ean14', data=ean14_gen, options={'includetext': True, 'textsize': '13', 'height': '3', 'width': '5'})

generates: https://ibb.co/S7zC822

Any tips what to put to options to get better image? If i try bigger font, it's out of canvas, instead of writing into bars.

I don't generate EAN's. This library is a fairly thin wrapper around postscriptbarcode (aka BWIPP). I suggest you read its docs or ask questions there about options. I can't really help with making barcodes, I don't even use this library any more, just maintain it.

Maybe someone else knows how to use TreePoem to get EAN pictures as shown in doc.
