FR: Add ability to add custom picture to labels

[steele-ntwrk]

Hi,

This feature request is to add the ability to add a custom picture to labels such as organization logos. The image could be kept in a local folder or be referenced using a file path.

Thoughts?

Cheers,
Steele

Hi @steele-ntwrk ! Do you mean logo inside the QR code, or put logo next to qr code image instead of text?

Hi @k01ek, Apologies I should be more specific, but a possibly an image on the right-hand side of text or to replace text.

I think maybe a Boolean value to add an image, the image path could be defined via ENV variable.

I am sort of new to programming and have been thinking about adding to this project as my first.

Cheers,
steele

@k01ek if you provide an option to update the logo inside the QR code that will be awesome.

I found a manual how to insert logos into an QRcode at https://www.geeksforgeeks.org/how-to-generate-qr-codes-with-a-custom-logo-using-python/ and managed to transfer the necessary bits to this plugin:

utilities.py:

• change all Image.newcalls to the Option RGB instead of P or L
• add a new function (which overloads the existing one without logo):

def get_qr(text, logofile, **kwargs):
    # extracted from example from https://www.geeksforgeeks.org/how-to-generate-qr-codes-with-a-custom-logo-using-python/

    logo = Image.open(logofile)
    basewidth = 100

    # adjust image size
    wpercent = (basewidth/float(logo.size[0]))
    hsize = int((float(logo.size[1])*float(wpercent)))
    logo = logo.resize((basewidth, hsize), Image.Resampling.LANCZOS)

    qr = qrcode.QRCode(**kwargs)
    qr.add_data(text)
    qr.make(fit=True)
    img = qr.make_image(fill_color="black", back_color="white").convert('RGB')

    # set size of QR code
    pos = (
        (img.size[0] - logo.size[0]) // 2,
        (img.size[1] - logo.size[1]) // 2
    )
    img.paste(logo, pos)

    return img

template_content.py:

• replace line qr_img = get_qr(url, **qr_args)
  with

        if config.get('custom_logo'):
                logofile = config.get('custom_logo')
                qr_img = get_qr(url, logofile, **qr_args)
        else:
                qr_img = get_qr(url, **qr_args)

In the netbox configuration.py you can add a plugin option custom_logo now which points to to logo image file to include.

It's still a rudimentary quick hack but it seems to be working. Please review and consider merging it into the code.
