Resize artwork in indesign CS6, javascript

[Yuliascript]

Hi,

I get user's input through dialog how much to enlarge or reduce artwork in % and than re-scale it based on that. When indesign does it in UI, it allows user to go back to 100% by just inputting 100% into re-size window. How can I access this information through my script, because right now if artwork was resized to 110%, request for 100% will not do anything in my script:

var myRectangle = myDoc.pages
.rectangles[0];
var myArt = myRectangle.graphics[0];
         var  xScale = myScale / 100;    
         var  yScale = myScale / 100;    
         myArt.horizontalScale = myArt.horizontalScale * xScale;     
          myArt.verticalScale = myArt.verticalScale * yScale;  

Thank you.

Hi Yulia,

Try the following it should work

var myRectangle = myDoc.pages
.rectangles[0];  
var myArt = myRectangle.graphics[0];  
var  xScale = myScale ;      
var  yScale = myScale ;      
myArt.horizontalScale = xScale;       
myArt.verticalScale = yScale; 

What you were doing is setting the scale with respect to the current scale, now if you set the scale initially at 5% it would have the correct result but after that if you send 100 as my scale value it will have no effect and the scale would remain 5, as xScale/yScale would be 1.

Thank you, Manan,

It makes perfect sense.

But for whatever reason when I try to run it, it stops at the line:

myArt.horizontalScale = xScale;

Thank you.

I know why. I had to add this:

myScale = eval (myScale);

before this:

myArt.horizontalScale = myScale;   
myArt.verticalScale = myScale;

i used a number value for setting myScale and it worked without eval. What value does your myScale hold before you run eval over it?

My number is coming from dialog box, so I think, script perceives it as string.
