Show warning(s) when an SVG is missing important information

[tcurdt]

The resulting gcode for this svg has dimensions that are 0.00something.
I assume svg2gcode does not like the width/height/viewbox setting here?

The viewBox looks fine to me. I'll debug this tomorrow, but in the meantime, you can try removing the 100%/100% width/height attributes. Set those to physical units if needed (in/cm).

This seems to work just fine.

I blame the tool for outputting the 100%.

[tcurdt]

Maybe it would be good to complain and show an error.

Hm - but now with...

I would expect it come out the correct size.

What dpi does this need when the exact dimensions are given?

[tcurdt]

I actually had to interpolate the dpi to 95.63 for it to come out correctly in the correct size 🤔

Can you share the image?

[tcurdt]

Not sure whether it's OK to attach here - but I could sent you a copy over a more private channel if that's OK with you?
