什么是作为PNG呈现的SVG图像？

Question

There's an svg image of Alabama's state flag @ http://en.wikipedia.org/wiki/File:Flag_of_Alabama.svg

The caption says "This image rendered as PNG in other sizes." I downloaded the 1,000-pixel size @ http://upload.wikimedia.org/wikipedia/commons/thumb/5/5c/Flag_of_Alabama.svg/1000px-Flag_of_Alabama.svg.png but it won't display on my web page. I opened it in Photoshop, copied it into a new window and saved it with a new file name, but it still doesn't display.

So I guess I was wrong when I thought "rendered as a PNG" means an image is a png. It's actually a SVG...with a .png extension?

Anyway, I just wondered what's going on here and what I need to do to download such images as pngs. Or is the only solution to take a screenshot?

Answer 1

To get the image as .svg just copy the source of the page (of the image) to an editor. Now save it as an .svg image

Answer 2

The PNG file you linked to (the ".png" link) is not an SVG. It is definitely a PNG.

I don't know why it isn't displaying for you, but it has nothing to do with SVG.
