SVGs rendering topping out at 1024px wide
Closed, ResolvedPublic


Author: stephenshep

On the English Wikipedia SVGs are redering in a more rasterized state than usual, this results in blocky images instead of smooth SVGs.

Version: 1.13.x
Severity: normal

Please be as specific as possible, including an example of a page with an image displaying incorrectly.

(Note that you may be using a browser with a 'full-page zoom' feature and have accidentally zoomed in the page, which will scale up all images and make them appear blocky.)

I'm using IE7 and have it set to the defaults just to make sure it's not me. Look at Image:Burma Flag.svg and Image:Government Ensign of the United Kingdom.svg . They both look great in Inkscape, but the white lines ar jagged correct? I tested on another computer (Linux) and it looked the same on Firefox something-or-other.

Are your thumbnail preferences set at 1280px or higher?

There seems to be something a bit wonky that's topping out the rasterization at 1024 pixels here, which bears investigation.

That's probably thanks to this default setting...

/** Don't scale a SVG larger than this */
$wgSVGMaxSize = 1024;

Probably a bit low for a default, given that the standard options array for Image: onscreen display includes a 1280px-wide option. :)

I've pushed the limit up to 2048 both live and in r34061
