Maintain aspect ratio of bottom banner?

<!-- button with scale9grid -->
<plugin name="button1" url="button.png"
align="center" edge="center" x="-25%"
scale9grid="12|9|74|71"
onhover="showtext(scale9grid button[br]click to toggle scale, hoverstyle);"
onclickA="tween(scale,3);set(onclick,call(onclickB));"
onclickB="tween(scale,1);set(onclick,call(onclickA));"
onclick="call(onclickA);"
/>

or set width to 100%
and height to XX pixels

Hi fellipe,

I think you are looking for the "prop" value property...

Quote from <plugin> Doc.

• width
  width of the plugin in absolute pixels or percents of the screenwidth
  set it to "prop" to allow scaling the width proportional to the height
  if nothing is set, the width of the source file will be set
• height
  height of the plugin in absolute pixels or percents of the screenheight
  set it to "prop" to allow scaling the height proportional to the width
  if nothing is set, the height of the source file will be set
