Exception converting SVG to PNG

[lkirkwood]

I am using svg2png for the second leg of a EMF -> SVG -> PNG conversion. Certain images are throwing the following exception:

Matrix.translate() takes 3 positional arguments but 4 were given

Any thoughts? Can I enable more verbose logging in some way?

• OS: Debian Bookworm
• Python: 3.11.2
• CairoSVG: 2.7.1

Hi!

Thanks for the report.

Could you please paste the whole backtrace? I suspect that the bug is here, but I’d like to be sure.

Thanks for the prompt response! Looks like you were correct.
