- | "t100,100r30,100,100s2,2,100,100r45s1.5"

- * rotate 45° around centre; scale 1.5 times relative to centre”. As you can see rotate and scale commands have origin

- > Colour Parsing
- # <ul>
- # <li>Colour name (“<code>red</code>”, “<code>green</code>”, “<code>cornflowerblue</code>”, etc)</li>
- # <li>#••• — shortened HTML colour: (“<code>#000</code>”, “<code>#fc0</code>”, etc)</li>
- # <li>#•••••• — full length HTML colour: (“<code>#000000</code>”, “<code>#bd2300</code>”)</li>
- # <li>rgb(•••, •••, •••) — red, green and blue channels’ values: (“<code>rgb(200, 100, 0)</code>”)</li>
- # <li>rgb(•••%, •••%, •••%) — same as above, but in %: (“<code>rgb(100%, 175%, 0%)</code>”)</li>
- # <li>rgba(•••, •••, •••, •••) — red, green and blue channels’ values: (“<code>rgba(200, 100, 0, .5)</code>”)</li>
- # <li>rgba(•••%, •••%, •••%, •••%) — same as above, but in %: (“<code>rgba(100%, 175%, 0%, 50%)</code>”)</li>
- # <li>hsb(•••, •••, •••) — hue, saturation and brightness values: (“<code>hsb(0.5, 0.25, 1)</code>”)</li>
- # <li>hsb(•••%, •••%, •••%) — same as above, but in %</li>
- # <li>hsba(•••, •••, •••, •••) — same as above, but with opacity</li>
- # <li>hsl(•••, •••, •••) — almost the same as hsb, see <a href="http://en.wikipedia.org/wiki/HSL_and_HSV" title="HSL and HSV - Wikipedia, the free encyclopedia">Wikipedia page</a></li>
- # <li>hsl(•••%, •••%, •••%) — same as above, but in %</li>
- # <li>hsla(•••, •••, •••) — same as above, but with opacity</li>
- # <li>Optionally for hsb and hsl you could specify hue as a degree: “<code>hsl(240deg, 1, .5)</code>” or, if you want to go fancy, “<code>hsl(240°, 1, .5)</code>”</li>
