|
<p>This class handles multiple color spaces, and offers various
|
|
static methods for converting colors from one space to another.</p>
|
|
|
|
<p>The constructor accepts the following color representations:
|
|
<ul>
|
|
<li>a named color, e.g. 'aliceblue' (the colorspace must be RGB)</li>
|
|
<li>an hexadecimal string representation, e.g. '#FF0000' (the colorspace must be RGB)</li>
|
|
<li>an hexadecimal number representation, e.g. 0xFF0000 (the colorspace must be RGB)</li>
|
|
<li>a triplet of numbers, e.g. [-1, 0, 1], [0, 128, 255] (the numbers must be within the range determined by the colorspace)</li>
|
|
</ul>
|
|
</p>
|
|
|
|
<p>Note: internally, colors are represented as a [r,g,b] triplet with r,g,b in [0,1].</p>
