hi.
i have a viewport for my application and i want to create another smaller
viewport whose width and height is in the same ratio as the original viewport.
i'm having trouble calculating it correctly.
// here's the call to the method that creates the 2nd, smaller viewport
setSubWindowSize(viewportWidth,viewportHeight); // the params are the width and
height of the original viewport.
public function setSubWindowSize(width:Number,height:Number):Void {
// calculate ratio of width to height
var ratio:Number = viewportHeight/viewportWidth;
var calculatedWidth:Number = ratio*height;
var calculatedHeight:Number = height;
}
so, if my original viewport is 300 x 400, then the ratio will be 1.33 but the
new ratio(calculatedHeight/calculatedWidth) gives 0.75. can anyone see what is
wrong with my calculations?
any help is very much appreciated. thanks.
matt.
