IM equivalent to Adobe JS action script

[thes4s67]

Hi everyone, can someone help me convert this adobe action script to something in imagemagick.

Code: Select all

#target photoshop
app.preferences.rulerUnits = Units.PIXELS;
 
var backgroundC = new SolidColor();
    backgroundC.rgb.red = 255;
    backgroundC.rgb.green = 255;
    backgroundC.rgb.blue = 255;
    backgroundColor = backgroundC;
   
var doc = activeDocument
 
doc.resizeCanvas(Math.max(doc.width,doc.height),Math.max(doc.width,doc.height))

Basically this takes the image and turns it into a square and adds white background. I use the script in Photoshop, but I believe this can be done FASTER with ImageMagick. Any help is greatly appreciated.
