Generate SVG image preview for page layouts

[Yuliya Bozhko]

Was just thinking that instead of generating and storing PNG images we could just show <svg> on page directly. Got some proof of concept in review that would need a bit of polishing.

Hello Yuliya,

Do all the browsers that we support, allow for the <svg> tag or do we need to be careful with certain browsers?

Thank you
Kristina

All browsers currently supported by Mahara support inline <svg> tag as far as I know.

Yep, SVG is supported in all modern browsers. Even IE9 (and up). Even the mobile browsers! http://caniuse.com/#feat=svg

Yuliya pushed a patch for this: https://reviews.mahara.org/#/c/3975/

Reviewing the code, I now see that it uses inline SVGs, whereas I was thinking of separate svg files. (i.e. the HTML file has an <svg> tag inside of it, and that has some <rect> tags inside it, and so forth)

This is slightly less supported than separate SVG files. But crucially, it's still supported by all our target browsers for Mahara 15.04, including IE9+, so still not a problem. http://caniuse.com/#feat=svg-html5
