Re: Including an EPS

[Mike Kilmer]

Thanks, Jean.

With upgrade, compilation still failed, but it was in fact the eps file and/or 
its format that compiler was choking on.

Here you can see the (truncated) diff btwn the (first) one that DID work (from 
my vector editor) and the one that pyqrcode generated:

diff --git a/longdarkroad.eps b/longdarkroad.eps
index 9050b61..2842f16 100644

--- a/longdarkroad.eps The working one
+++ b/longdarkroad.eps The breaking one

This is the Python code I've been using to generate the EPS, which utilizes the 
Python Image Library (via qrcode):

# Importing library
import qrcode

# Data to encode
data = 
"https://www.dropbox.com/scl/fo/frn8pgmnsfmkytdnzo2wp/h?dl=0&rlkey=r9sjjz396ij5r9clg14c47cga";

# Creating an instance of QRCode class
qr = qrcode.QRCode(version=1, box_size=30, border=3)

# Adding data to the instance 'qr'
qr.add_data(data)

qr.make(fit=True)
img = qr.make_image(fill_color='#000000', back_color='white')

img.save('longdarkroad.eps', lossless = True)
