var fileNames = [ "Input1.png", "Input2.png" ]

var doc = new aw.Document()
var builder = new aw.DocumentBuilder(doc)

shapes = fileNames.map(fileName => builder.insertImage(fileName))

// Calculate the maximum width and height and update page settings 
// to crop the document to fit the size of the pictures.
pageSetup = builder.pageSetup
pageSetup.pageWidth = Math.max(...shapes.map(shape => shape.width));
pageSetup.pageHeight = shapes.reduce((sum, shape) => sum + shape.height, 0);
pageSetup.topMargin = 0
pageSetup.leftMargin = 0
pageSetup.bottomMargin = 0
pageSetup.rightMargin = 0

doc.save("Output.png")
