I installed latest svglib and reportlab-3.6.9-cp38-cp38-win_amd64.whl on python-3.8.1.amd64 on my windows 10 64 bits.

however the generated png and pdf is in a mess

the original svg and generated pdf/png is in the attached zip tmp.zip

from svglib.svglib import svg2rlg
from reportlab.graphics import renderPDF, renderPM

drawing = svg2rlg("tmp.svg")
renderPDF.drawToFile(drawing, "file.pdf")
renderPM.drawToFile(drawing, "tmp.png", fmt="PNG")

Thank you for raising your first issue! Your help to improve svglib is much appreciated!

Your original svg looks weird, when opening it with inkscape, I'm only seeing a blank page.

retsyo commented 2 years ago

but all of Edge/Chrome/FireFox/CairoSVG can render it correctly

FWIW, it looks ok in https://www.svgviewer.dev.

When debuging this issue, I find different issues. It looks like <symbol> handling is broken in several ways currently in svglib. I'll see if I can do something. I started in #329 by only rendering <symbol> when referenced, as the specs says (A [‘symbol’] element itself is not rendered.) It is not fixing this issue yet, as after that patch, your document will be blank.

330 was another issue hit by your file.

no, if I use the lastet cloned svglib, my script in the beginning post can only produce blank PDF and PNG, in other words, there is no character in PDF and PNG
