TagCanvas 1.12
Published
This version of TagCanvas has a few new features, the first of which comes
from the new option outlineMethod. This option changes the
way that the highlighted tag under the cursor appears. The default setting
of "outline" looks a lot like the old outline method, but with the
rectangle drawn at the same depth as the selected tag (so parts of it could
be covered by any tags that are closer to the front of the cloud).
The old way of displaying the outline on top is available using "classic" as the setting, or there are two new settings that looks quite different. The "block" setting draws a solid rectangle behind the active tag, and the "colour" setting draws the text (or image) of the active tag in the outline colour. The "colour" method does not support pulsating at the moment, but I expect I'll get it working in a future version. Colour doesn't work for images on IE8 and below either, but I don't expect to fix that before my next skiing holiday to Hell.
The other new features are multi-font and multi-colour support. The way
these work is fairly simple: set the textColour or
textFont options to null, and TagCanvas will
pick up the font and/or colour to use for the tags from the links used
to generate the cloud. That doesn't sound very clear, so I expect I'll
upload a page of examples soon to explain it a bit better.
The last couple of changes in this version fix the default
pulsateTo for the stand alone version to be 1 (i.e. not
pulsating), the same as used in the jQuery version and what it says
the default should be in the options
list. Finally, this version doesn't draw anything when the cloud is
not moving, which reduces the amount of work the browser has to do.
As per usual, the updated scripts are available from the TagCanvas page.
