Dear jorge,

my image viewer have 5 button, [zoom in] [zoom out] [reset to original position] [zoom 4x] [zoom 8x].

actually i'm doing a medical image viewer. so its need a function like microscope.. zoom 4 time & 8 times.


on the keyframe, here is my zoom function.

//zoom
zoom = function( action, type, soul, factor){
   if(action == "start"){
      if(type == "plus"){
         this[soul].onEnterFrame = function(){         
            with(this){
               _xscale += factor;
               _yscale += factor;               
            }
         }
      }
      if(type == "minus"){
         this[soul].onEnterFrame = function(){
            if(this._xscale>101){
               with(this){
                  _xscale += factor;
                  _yscale += factor;               
               }
            }
         }
      }      
   }else{
      delete this[soul].onEnterFrame;
   }
}



for my [zoom in]

//zoom in
on (press) {
   zoom("start", "plus", "image_mc", 5);
}
on (release) {
   btn4x.enabled = false,
   mc_4x._alpha = 25;
   btn8x.enabled = false,
   mc_8x._alpha = 25;
   zoom("stop", null, "image_mc", null);
   tip("");   
}
on (rollOver) {
   tip("Zoom in");
}
on (rollOut) {
   tip("");
}


for my [zoom 8x]

//zoom 8x
on (press) {
   zoom("start", "plus", "image_mc", 100);
}
on (release) {
   btn8x.enabled = false,
   mc_8x._alpha = 25;
   btn4x.enabled = false,
   mc_4x._alpha = 25;
   zoom("stop", null, "image_mc", null);
   tip("");   
}
on (rollOver) {
   tip("8x");
}
on (rollOut) {
   tip("");
}

basically.. my problem is.. when user press the [zoom 4x] button, it will zoom 50% from its original image. Then it will stop.

Wut i having here.. if user press the key for too long.. it will multiply the zoom ratio.

hope u understand wut i mean.

thanks...

p/s : i know dat my question sound stupid.. and i think the was and easy solution but my newbie brain cant think the solution of it..

Add a fith parameter, the maximun :

zoom = function(action, type, soul, factor, max){

and add an if to limit the zoom


 ...
 this[soul].onEnterFrame = function(){         
            with(this){
               _xscale += factor;
               _yscale += factor;               
            }
 }
 if(_xscale>=max) delete this[soul].onEnterFrame 
 ...
