| 13 | State of SVG and Canvas in Modern Browsers |
| 14 | ========================================== |
| 15 | |
| 16 | __By: Alastair Tse - Last Updated: 27 April 2006__ |
| 17 | |
| 18 | |
| 19 | My friends, just like HTML and CSS, different browsers support |
| 20 | different subsections of the SVG and Canvas specification. As part of |
| 21 | my work on PlotKit, the next generation javascript plotting library, |
| 22 | I've decided to summarise all the quirks in SVG and Canvas support. |
| 23 | |
| 24 | Browsers Considered |
| 25 | =================== |
| 26 | |
| 27 | I am looking at browsers that are considered "modern" as of |
| 28 | March 2006. These include: |
| 29 | |
| 30 | * [Safari 2.0.x][Safari] (W/ [Adobe SVG Plugin][ASV]) |
| 31 | * [Firefox 1.5.x][Firefox] |
| 32 | * [Opera 9.0 Preview 2][OperaSnapshot] |
| 33 | * [Internet Explorer 6][IE6] (w/ [Adobe SVG Plugin][ASV]) |
| 34 | |
| 35 | I am also looking at some experiemental browsers as of March 2006. |
| 36 | |
| 37 | * [Internet Explorer 7 beta 2 preview + ASV][IE7] |
| 38 | * [Safari WebKit+SVG Nightly 2006-03-11][WebkitNightly] |
| 39 | * [Firefox Deerpark Nightly 2006-03-11][FirefoxNightly] |
| 40 | |
| 41 | [Safari]: http://apple.com/safari/ |
| 42 | [Firefox]: http://www.mozilla.com/firefox/ |
| 43 | [OperaSnapshot]: http://snapshot.opera.com/ |
| 44 | [IE6]: http://www.microsoft.com/windows/ie/ |
| 45 | [ASV]: http://www.adobe.com/svg/ |
| 46 | [IE7]: http://www.microsoft.com/windows/IE/ie7/default.mspx |
| 47 | [WebkitNightly]: http://nightly.webkit.org/ |
| 48 | [FirefoxNightly]: http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-trunk/ |

| 51 | Canvas |
| 52 | ====== |
| 53 | |
| 54 | * Canvas is defined by the WHATWG in what is known as the |
| 55 | [Web Applications 1.0 specification][WHATWG] |
| 56 | |
| 57 | Supporting Browsers |
| 58 | ------------------- |
| 59 | |
| 60 | * Safari 2.0 and above. |
| 61 | * Opera 9.0 and above. |
| 62 | * Firefox 1.5 and above. |
| 63 | |
| 64 | Quirks |
| 65 | ------ |
| 66 | |
| 67 | * __Safari__ will forget a path after ``fill()`` or ``stroke()`` has |
| 68 | been called. Therefore, if you need to fill and stroke the same |
| 69 | path, you must draw the path out twice. |
| 70 | |
| 71 | * __Opera__ will not obey ``stroke()`` for arc paths. |
| 72 | |
| 73 | * __Firefox__ and __Opera__ will not draw shadows even with |
| 74 | ``shadowStyle`` or ``shadowOffset`` is set on the context object. |
| 75 | |
| 76 | SVG |
| 77 | === |
| 78 | |
| 79 | * SVG support is either provided natively, or through the Adobe SVG |
| 80 | Viewer (ASV). |
| 81 | |
| 82 | Supporting Browsers (Inline) |
| 83 | ---------------------------- |
| 84 | |
| 85 | * Safari 2.0 + ASV |
| 86 | * Internet Explorer 6 + ASV |
| 87 | * Safari Webkit+SVG Nightly |
| 88 | * Opera 9.0 and above |
| 89 | * Mozilla Firefox 1.5 and above |
| 90 | |
| 91 | Quirks (Inline) |
| 92 | --------------- |
| 93 | |
| 94 | * __Safari Nightly__ will not render any ``text`` elements when |
| 95 | inlined. (Will do so if using ``embed``) |
| 96 | |
| 97 | * __Safari 2.0 + ASV__ will not respect inlined SVG. |
| 98 | |
| 99 | * __Internet Explorer 6 + ASV__ will only parse inlined SVG if the |
| 100 | following is added to the HTML and all SVG elements are in the |
| 101 | correct namespace ``svg:``. |
| 102 | |
| 103 | <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en" |
| 104 | xmlns:svg="http://www.w3.org/2000/svg" |
| 105 | xmlns:xlink="http://www.w3.org/1999/xlink"> |
| 106 | ... |
| 107 | <body> |
| 108 | <!-- START Required for IE to support inlined SVG --> |
| 109 | <object id="AdobeSVG" |
| 110 | classid="clsid:78156a80-c6a1-4bbf-8e6a-3cd390eeb4e2" width="1" |
| 111 | height="1"></object> |
| 112 | <?import namespace="svg" implementation="#AdobeSVG"?> |
| 113 | <!-- END Required for IE to support inlined SVG --> |
| 114 | <svg:svg width="300" height="300" baseProfile="full" version="1.1"></svg:svg> |
| 115 | </body> |
| 116 | </html> |
| 117 | |
| 118 | * __Mozilla Firefox (1.5 and nightly) on Mac__ will not render |
| 119 | ``text`` elements when inlined. Note that it does for Linux and Windows. |
| 120 | |
| 121 | * __Opera 9__ will refuse to draw an element if attribute ``filter`` |
| 122 | is defined. |
| 123 | |
| 124 | * __Internet Explorer 7b2p + ASV__ will not work with the Adobe SVG Viewer. |
