Why did #Inkscape make it more difficult to chaneg the background color to transparenet, and since when?!??
It is now document properties, and pressing this unclear "Page" button as display?! no remove background color quick option!?
This is NOT a display property, but even export and printing!!!
Can you remember what is used to be?
That color you show isn't exported, isn't shown in any svg viewer... it's just for show.
It's not the background color of the image. This is because SVG doesn't support background colors, there's no such thing. Unfortunately.
in my images that I have from long during the B2G (fxos) I made svgs for icons and they were transparenbt. I opened them in inkscape and had to change it. I still remember this dialog where it states "background color".
SVGs are always transparent.
Just set the default background color to be checkerboard, I think that's what you want.
Obviously you can't set "transparent" because then you'd see things behand your inkscape window.
@doctormo got it working; for new stuff I don't realize this at all. these files are just old..
Confirmation about their age ;-)
Also had to use:
magick -background transparent icon.svg -resize 512x512 PNG32:public/icon-512.png
and specifically specify " -background transparent" BEFORE the filename, otherwise it would render without the alpha channel.
I do not recommend using imge magic to render svg files to pngs. Only because you may have features in your svg which image magic doesn't support.
If you can, use `inkscape input.svg -o output.png`
@doctormo good point!
I mostly avoided filters. I had to make sure this can run in a CI. I'll add a big fat reminder!
