Hello.
I make the SVG file in Inkscape, but I can open it only with Inkscape. I try:

• The image viewer: the transparent image.
• GIMP: the thansparent image.
• The browsers (firefox, chrome, qupzilla): nothing.
• A HTML file (with tags <img>, <object>): nothing.

I copy this file in the windows and I see it with the browsers and in the HTML file.
Thank for any ideas.

What type of objects do you have in your SVG?

Are your objects within the Page area?

Yep, it's most probably that your objects are not within the page area, which is the rectangle with the black outline in Inkscape.

Yes, it was the probleme.
But why it worked in the windows?

Was it some browser on windows that you didn't or couldn't use on linux, like IE or Edge? They might have different "rules" about how to display SVG. They're usually not the browsers who lead in implementing web standards the fastest, though I'm no expert on this.

Could you share the SVG file with us, so we can investigate? Some of us are amazing guessers, but not all the time
