SVG 图标在透明背景下变形

Question

I am trying to display an svg icon against transparent background, however, when the transparent background is applied the svg looks like this:

ideally, I am expecting the svg icon to look like the first svg icon. One important thing to note here is that the background will dynamically be applied.

Here is the svg code:

Answer 1

get rid of the fill="none" inside svg tag, if you want background dynamically applied.

also you could look closer to your svg on https://yqnn.github.io/svg-path-editor/

I changed it a bit

transparent globe svg inside my button

it looks exactly as you wanted

Answer 2

The posted image with the transparent background looks like the checkered background in Photoshop. Not a real life situation.

However you are mentioning that The background is dynamic. It can be changed to any color. and this is a problem since your icon is white.

Here is a what you can do: you can use an outline filter around your icon. This way it will be visible on every background.

As an observation: 16px width and height is way too small. I would recomend at least 24px.

Answer 3

At this scale, a shape that uses fill rather than just stroke to define the shape could give you problems because anti-aliasing might just give up.

If you don't want to recreate the shape using single strokes, then at least make it bigger and add a stroke-linejoin/round- because the shape itself isn't particularly well drawn.
