cairosvg: error: no such option: --output-width #30

Hi,

With cairoSVG (pyhton3-cairosvg package), I got the following error message: cairosvg: error: no such option: --output-width

I changed "--output-width" to "-W" and "--output-height" to "-H" (line 26 of the run.sh file).

The error message is gone, and the display is good.

Thanks for reporting that, did you install cairosvg using apt or pip? What version appears when you run cairosvg --version ?

Mine is 2.5.0 installed via apt

I wonder if the arguments are for newer (or older) versions of cairosvg maybe.

Strangely for me when I use -W and -H the image that's generated is the wrong dimensions and doesn't display on the epaper screen (it errors with 'wrong dimensions').

I had to use --output-width and --output-height to get it working.

Thanks for the quick return.

The package was python3-cairosvg, installed via apt (Raspbian Buster). The version was 1.0.20.

I removed the package (via apt) and installed it with pip3. Now it shows version 2.5.2, and it's working with either combination of --output-width and --output-height or -W and -H.

Installing cairosvg (version 2.5.2) with pip3 solved the issue.
