Dear Zoltan,
Thanks for the trick.
I'm writing a function that takes a list of figures (and headers) and
builds a table like you suggest.
In the function I do
import base64
pngs = []
for fn in images: # loop over the input file names
with open(fn, "rb") as f:
pngs.append('data:image/png;base64,' +
base64.b64encode(f.read()))
But I get the following error: on the last line:
TypeError: Can't convert 'bytes' object to str implicitly
Is there a way to disable table lines in HTML?
for reference: I'm using python3.3
Cheers,
Fra
