I need to convert PNG icons into SVG format. What size should the initial PNGs be? Do I need to make the icons smaller (they will be 30 x 30 px on the site) before I save them as SVGs?

It seems that with potrace installed, I can just run magick convert x.png x.svg or magick convert x.jpg x.svg.However this just returns a deformed image in black and white, and I need the svg image to be in full color. Additionally, I really need the file format to be svg because svg images are small and portable, and I don't have a lot of disk space on my server.Does anyone know how to convert png/jpeg to svg while retaining color?
is there a way to make the background image of chrome theme resize with the height of the window? If so, can I also make the image resize with the height until it hist a certain ratio, and then resize with the width of the window?
It's not possible. Chromium source code doesn't have any stretching/sizing modes as you can see: theme_properties.h, theme_properties.cc and theme_service.cc
I've tried specifying an SVG image with width="100%" height="100%" for the background but it wasn't rendered, looks like only raster images can be used (WEBP, JPG, PNG, etc).
I tried use jpeg format, it resized itself, without anything added to manifest.json
I downloaded this svg map and used ImageMagick to convert to PNG format. However, my output PNG images don't look very well: the white borders between countries almost don't show. On the other hand, the rendered versions on the Wikimedia site look great.
Is there any option I can pass to ImageMagick to prioritize borders?
Viewing the PNG in an image viewer, it is normal.
Viewing the PNG as an overlay in Google Earth, random black rectangles are added near the transparent regions of the image.
How to avoid this in either PNG generation or in KML?
The PNG is BufferedImage.TYPE_4BYTE_ABGR
When I open a Tango SVG icon file and export it (using Inkscape) to a 16x16 png, I get a rather blurry image. Instead, the "official" 16x16 render is extremely sharp. How did they do it? Did they pixel-paint the icons at small resolutions?
Compare and for an example.
Gimp has a better scaling algorithm than Inkscape.
I Export from inkscape to 256x256 pixels and then scale to 16x16 in Gimp.
