TagCanvas是一个基于HTML5 Canvas技术开发的标签云动画。
还提供一个以jQuery插件形式实现的版本号。
它支持文本和图片两种格式,可以以Sphere, hcylinder 或 vcylinder三种形状显示。
TagCanvas还支持IE浏览器(利用ExplorerCanvas实现)。

decel | 0.95 | Deceleration rate when mouse leaves canvas |
minBrightness | 0.1 | Brightness of tags at farthest point (0.0-1.0) |
textColour | "#ff99ff" | Colour of the tag text |
textHeight | 15 | Height of the tag text font (in pixels) |
textFont | "Helvetica, Arial, sans-serif" |

outlineOffset | 5 | Distance of outline from text, in pixels |
pulsateTo | 1.0 | Pulsate outline to this opacity (0.0-1.0) |
pulsateTime | 3 | Pulse rate, in seconds per beat |
depth | 0.5 | Controls the perspective (0.0-1.0) |
initial | null | Initial rotation, with horizontal and vertical as an array, e.g. [0.8,-0.3]. Values are multiplied by maxSpeed. |
freezeActive | false | Set to true to pause movement when a tag is highlighted. |
frontSelect | false | Set to true to prevent selection of tags at back of cloud. |
txtOpt | true | Text optimisation, converts text tags to images for better performance. |
txtScale | 2 | Scaling factor of text when converting to image in txtOpt mode. |
reverse | false | Set to true to reverse direction of movement relative to mouse position. |
hideTags | false | Set to true to automatically hide the tag list element if TagCanvas is started successfully. |
zoom | 1.0 | Adjusts the relative size of the tag cloud in the canvas. Larger values will zoom into the cloud, smaller values will zoom out. |
wheelZoom | true | Enables zooming the cloud in and out using the mouse wheel or scroll gesture. |
zoomStep | 0.05 | The amount that the zoom is changed by with each movement of the mouse wheel. |
zoomMax | 3.0 | Maximum zoom value. |
zoomMin | 0.3 | Minimum zoom value. |
shadow | "#000000" | Colour of the shadow behind each tag. |

weightSize | 1.0 | Multiplier for adjusting the size of tags when using a weight mode of size or both. |
weightGradient | {0:'#f00', 0.33:'#ff0', 0.66:'#0f0', 1:'#00f'} |
The colour gradient used for colouring tags when using a weight mode of colour or both. |
weightFrom | null | The link attribute to take the tag weight from. The default of null means that the weight is taken from the calculated link font size. |
shape | "sphere" | The shape of the cloud. Currently supported are sphere, hcylinder for a cylinder that starts off horizontal and vcylinder for a cylinder that starts off vertical. |
lock | null | A value of "x" limits rotation of the cloud to the (horizontal) x-axis, and a value of "y" limits rotation to the (vertical) y-axis. (These are strings, so the quotes are required) |
