opacity Library Method
Short Description: Set opacity of associated HTML element
Signature: t.opacity (o)
Group: HTMLControl
Class: transition Class
Sets the opacity to o of the element associated with the current transition before playing the
main animation. The current implementation actually performs the style change
immediately when called.
Setting opacity to 0, i.e. making the element totally transparent, is another way of hiding
an element. In contrast to setting visibility to hidden however a totally transparent HTML
element still receives mouse events. This is sometimes very useful, if the HTML
element is drawn on canvas while the HTML element itself is shown transparently (i.e. not shown)
but still receives mouse events. See forwardingController Note 2 for an example.
Examples
taccgl.a("testimg").paint().opacity().opacityFinal().to(500,500,1).start(); | RUN |
taccgl.a("testimg").paint().opacity(0.5).opacityFinal().to(500,500,1).start(); | RUN |
taccgl.a("testimg").paint().opacityFinal().to(500,500,1).start(); | RUN |
taccgl.a("testimg").startTime(1).paint().opacity().opacityFinal().to(500,500,1).start(); | RUN |
taccgl.a("testimg").startTime(1).paint().opacity().opacityFinal().showBefore().to(500,500,1).start(); | RUN |
