Hello,

I have an issue with upcean.fonts when I try to use validate_create_barcode.

In fact it looks like to don't recognized the fontpathocra in my laptop.
This is my error code :

@KazukiPrzyborowski do you have any idea to fix this problem ? I already install and uninstall the PIL and Pillow packages

Thanks for creating this package. I'm digging through your code to see how to use it, but I'm not familiear with what you're doing. Is there any simple documentation you could add to reademe.rst?

I follow the example file and run the "ean13" correct but cannot make the codabar run correctly. Can you provide an instruction for each barcode type?

Is there a way to generate the final barcode file in memory rather than on disk? Currently we have to force a delete on the filesystem for every barcode (we possibly have 10s of thousands) because validate_create_barcode saves to disk. This package desperately needs some documentation

I'm having this error when I'm trying to install this package:

Could not find a version that satisfies the requirement PIL (from PyUPC-EAN==2.7.14->-r requirements/common.txt (line 28)) (from versions: )
No matching distribution found for PIL (from PyUPC-EAN==2.7.14->-r requirements/common.txt (line 28))

It's not happening if I install Pillow package manually before installing it. May be dependencies needs a fix.

This error occurs after freezing an application using cx_freeze, which utilises PyUPC-EAN.

Hi, How can i convert a code to svg ?
create_upce_barcode(upc,outfile="./upce.svg",......, mageoutlib="cairosvg") this generates a png again

I am writing a GUI application for Windows which imports upcean from PyUPC-EAN to validate manually-input barcode numbers and generate a barcode image if the code is valid.

When run from the python interpreter, this works perfectly.

Here is a snippet of code where the verification/image generation is happening...

if entered_count == 13:
    bcode = upcean.oopfuncs.barcode(type="ean13", code=str(number)
if entered_count == 14:
    bcode = upcean.oopfuncs.barcode(type="itf14", code=str(number))
    bcode.filename = "./" + number + ".png"
validbcode = bcode.validate_draw_barcode()
if validbcode:

Which runs perfectly fine under the python interpreter.

However, after freezing the application using, say, cx_freeze, the same segment of code generates an AttributeError...

AttributeError: 'barcode' object has no attribute 'validate_draw_barcode'

So it looks like something in the PyUPC-EAN package doesn't get included during the cxfreeze operation.

I have just tried using pyinstaller and get the same result.

I have tried specifically --include-module upcean ehwn using the cx_freeze script, to no avail, and as I stated above, I get the same non-working result when the program is frozen using pyinstaller.

Also, your upc-example.py script works fine when run from the python interpreter, but the same error occurs if it's frozen either with cx_freeze or pyinstaller.
