Center object inside another object in illustrator script

[shaig khaligli]

I have a simple problem, but I haven't found a solution it.

I have a object and rectangle grouped together and want to scale the object proportionally and have it centered inside the rectangle.

I'm looking for an automated solution to this because I have a lot of objects that need to be scaled and centered like this.

The art I'm working with is similar to this.

You simply do pageItem.resize(w, h).

#target illustrator

function test(){

  var doc = app.activeDocument;

  var obj = doc.pathItems.getByName("obj");

  obj.resize(150, 150);

};

test();

Silly-V​ thanks for response !

But I need different solution. I have different sizes of vector objects in artboard. I want to add each of them to groupped standart sized rectangles and make the icons be center and fit the rectangle. I just need script to make below " Before - After " thing.

How do you decide what % of height is to be smaller than the rectangle, which gives it such amount of padding room?

I guess icon's height has to be 80% of rectangle's height. Actually I want to resize all my icons in artboard proportionally / keeping the aspect ratio. Let's say my rectangle should be 500x500px. My icon's height should be not more than 400px.

here's some pseudo code that may help..

var icon = the icon artwork

var background = the background square

var iconDimension,scale;

//get the largest dimension of the icon

if icon.width > icon.height

    iconDimension = icon.width;

else

    iconDimension = icon.height;

//get the scale percentage

if iconDimension < background.width

    scale = (iconDimension / background.width) * 100

else

    scale = (background.width / iconDimension) * 100

//get 80% of the scale

scale = scale*.8;

//resize the icon

icon.resize(scale,scale);

//make sure the icon is still centered in the background box

icon.left = (background.left + background.width/2) - icon.width/2

icon.top = (background.top - background.width/2) + icon.height/2
