* Element.transform

[ method ]

* Adds transformation to the element which is separate to other attributes,

* i.e. translation doesn’t change `x` or `y` of the rectange. The format
|
||
* of transformation string is similar to the path string syntax:
|
||
| "t100,100r30,100,100s2,2,100,100r45s1.5"
|
||
* Each letter is a command. There are four commands: `t` is for translate, `r` is for rotate, `s` is for
|
||
* scale and `m` is for matrix.
|
||
*
|
||
* There are also alternative “absolute” translation, rotation and scale: `T`, `R` and `S`. They will not take previous transformation into account. For example, `...T100,0` will always move element 100 px horisontally, while `...t100,0` could move it vertically if there is `r90` before. Just compare results of `r90t100,0` and `r90T100,0`.
|
||
*
|
||
* So, the example line above could be read like “translate by 100, 100; rotate 30° around 100, 100; scale twice around 100, 100;
|
||
* rotate 45° around centre; scale 1.5 times relative to centre”. As you can see rotate and scale commands have origin
|
||
* coordinates as optional parameters, the default is the centre point of the element.
|
||
* Matrix accepts six parameters.

> Gradients
|
||
* Linear gradient format: “`‹angle›-‹colour›[-‹colour›[:‹offset›]]*-‹colour›`”, example: “`90-#fff-#000`” – 90°
|
||
* gradient from white to black or “`0-#fff-#f00:20-#000`” – 0° gradient from white via red (at 20%) to black.
|
||
*
|
||
* radial gradient: “`r[(‹fx›, ‹fy›)]‹colour›[-‹colour›[:‹offset›]]*-‹colour›`”, example: “`r#fff-#000`” –
|
||
* gradient from white to black or “`r(0.25, 0.75)#fff-#000`” – gradient from white to black with focus point
|
||
* at 0.25, 0.75. Focus point coordinates are in 0..1 range. Radial gradients can only be applied to circles and ellipses.

|

# <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(•••%, •••%, •••%) — 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>
