| 52 | <h1> State of SVG and Canvas in Modern Browsers</h1> |
| 53 | <p> <strong>By: Alastair Tse - Last Updated: 27 April 2006</strong> |
| 54 | </p> |
| 55 | <p>My friends, just like HTML and CSS, different browsers support |
| 56 | different subsections of the SVG and Canvas specification. As part of |
| 57 | my work on PlotKit, the next generation javascript plotting library, |
| 58 | I've decided to summarise all the quirks in SVG and Canvas support. |
| 59 | </p> |
| 60 | |
| 61 | <h1> Browsers Considered</h1> |
| 62 | <p>I am looking at browsers that are considered "modern" as of |
| 63 | March 2006. These include: |
| 64 | </p> |
| 65 | <ul> |
| 66 | <li> |
| 67 | <a href="http://apple.com/safari/">Safari 2.0.x</a> (W/ <a href="http://www.adobe.com/svg/">Adobe SVG Plugin</a>) |
| 68 | </li> |
| 69 | |
| 70 | <li> |
| 71 | <a href="http://www.mozilla.com/firefox/">Firefox 1.5.x</a> |
| 72 | </li> |
| 73 | |
| 74 | <li> |
| 75 | <a href="http://snapshot.opera.com/">Opera 9.0 Preview 2</a> |
| 76 | </li> |
| 77 | |
| 78 | <li> |
| 79 | <a href="http://www.microsoft.com/windows/ie/">Internet Explorer 6</a> (w/ <a href="http://www.adobe.com/svg/">Adobe SVG Plugin</a>) |
| 80 | </li> |
| 81 | </ul> |
| 82 | <p>I am also looking at some experiemental browsers as of March 2006. |
| 83 | </p> |
| 84 | <ul> |
| 85 | <li> |
| 86 | <a href="http://www.microsoft.com/windows/IE/ie7/default.mspx">Internet Explorer 7 beta 2 preview + ASV</a> |
| 87 | </li> |
| 88 | |
| 89 | <li> |
| 90 | <a href="http://nightly.webkit.org/">Safari WebKit+SVG Nightly 2006-03-11</a> |
| 91 | </li> |
| 92 | |
| 93 | <li> |
| 94 | <a href="http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-trunk/">Firefox Deerpark Nightly 2006-03-11</a> |
| 95 | </li> |
| 96 | </ul> |
| 97 | |
| 98 | <h1> Canvas</h1> |
| 99 | <ul> |
| 100 | <li> |
| 101 | Canvas is defined by the WHATWG in what is known as the |
| 102 | <a href="http://whatwg.org/specs/web-apps/current-work/">Web Applications 1.0 specification</a> |
| 103 | </li> |
| 104 | </ul> |
| 105 | |
| 106 | <h2> Supporting Browsers</h2> |
| 107 | <ul> |
| 108 | <li> |
| 109 | Safari 2.0 and above. |
| 110 | </li> |
| 111 | |
| 112 | <li> |
| 113 | Opera 9.0 and above. |
| 114 | </li> |
| 115 | |
| 116 | <li> |
| 117 | Firefox 1.5 and above. |
| 118 | </li> |
| 119 | </ul> |
| 120 | |
| 121 | <h2> Quirks</h2> |
| 122 | <ul> |
| 123 | <li><p> <strong>Safari</strong> will forget a path after <code>fill()</code> or <code>stroke()</code> has |
| 124 | been called. Therefore, if you need to fill and stroke the same |
| 125 | path, you must draw the path out twice. |
| 126 | </p> |
| 127 | |
| 128 | </li> |
| 129 | |
| 130 | <li><p> <strong>Opera</strong> will not obey <code>stroke()</code> for arc paths. |
| 131 | </p> |
| 132 | |
| 133 | </li> |
| 134 | |
| 135 | <li><p> <strong>Firefox</strong> and <strong>Opera</strong> will not draw shadows even with |
| 136 | <code>shadowStyle</code> or <code>shadowOffset</code> is set on the context object. |
| 137 | </p> |
| 138 | |
| 139 | </li> |
| 140 | </ul> |
| 141 | |
| 142 | <h1> SVG</h1> |
| 143 | <ul> |
| 144 | <li> |
| 145 | SVG support is either provided natively, or through the Adobe SVG |
| 146 | Viewer (ASV). |
| 147 | </li> |
| 148 | </ul> |
| 149 | |
| 150 | <h2> Supporting Browsers (Inline)</h2> |
| 151 | <ul> |
| 152 | <li> |
| 153 | Safari 2.0 + ASV |
| 154 | </li> |
| 155 | |
| 156 | <li> |
| 157 | Internet Explorer 6 + ASV |
| 158 | </li> |
| 159 | |
| 160 | <li> |
| 161 | Safari Webkit+SVG Nightly |
| 162 | </li> |
| 163 | |
| 164 | <li> |
| 165 | Opera 9.0 and above |
| 166 | </li> |
| 167 | |
| 168 | <li> |
| 169 | Mozilla Firefox 1.5 and above |
| 170 | </li> |
| 171 | </ul> |
| 172 | |
| 173 | <h2> Quirks (Inline)</h2> |
| 174 | <ul> |
| 175 | <li><p> <strong>Safari Nightly</strong> will not render any <code>text</code> elements when |
| 176 | inlined. (Will do so if using <code>embed</code>) |
| 177 | </p> |
| 178 | |
| 179 | </li> |
| 180 | |
| 181 | <li><p> <strong>Safari 2.0 + ASV</strong> will not respect inlined SVG. |
| 182 | </p> |
| 183 | |
| 184 | </li> |
| 185 | |
| 186 | <li><p> <strong>Internet Explorer 6 + ASV</strong> will only parse inlined SVG if the |
| 187 | following is added to the HTML and all SVG elements are in the |
| 188 | correct namespace <code>svg:</code>. |
| 189 | </p> |
| 190 | |

| 192 | </ul> |
