SVG Icons

Steven R. Baker
Heya folks!

I need to load SVG images (for icons) in my application. I've searched
my 6.1 image for SVG, but haven't found anything.

Is there a library for loading SVGs? I'd really like to get them
directly into instances of Form if possible, but I'm flexible. :)

Thanks!

-Steven

Hi,

this is not really tested, but you can try to do the following

(installation)
a) install XMLParser from catalog
b) in monticello browser open Pharo/Athens and load latest version of Athens-SVG package

(usage)
Then you import SVG XML using Converter and paint it on a surface, which you convert to Form.

```
contents := (ZnEasy get: 'https://s.cdpn.io/3/kiwi.svg') contents.

xmlDoc := XMLDOMParser parse: contents.

svg := AthensSVGConverter new importXMLDocument: xmlDoc.
svg transform: 'scale(0.5)'.

extent := 500 @ 500.

surface := AthensCairoSurface extent: extent.
surface drawDuring: [ :aCanvas | svg renderOn: aCanvas ].
surface asForm.
```

That is a very cool example !

Some nit picking (just trying to help make examples/snippets even more sexy).

The shortest expression to get to the contents of a URL, using only unary selectors is

  'https://s.cdpn.io/3/kiwi.svg' asUrl retrieveContents.

XMLDomParser's API also has the option #parseURL: so the following would also work

  XMLDomParser parseURL: 'https://s.cdpn.io/3/kiwi.svg'.

I believe that call actually has some additional functionality too.
