For some tests in UFT I need to start the chrome scanner maximized but with a certain zoom. To start maximized I have seen that you have to add the flag -start-maximized , but I have not found a flag to start with the zoom of 70%.
C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --profile-directory="Profile 3" -start-maximized
I do not know if there is an easier way but what I can think of is that you install in chrome the extension Tampermonkey and create a custom script that looks like this:
// ==UserScript==
// @name Zoom predeterminado
// @description Pone un zoom personalizado a las paginas del include
// @include https://www.google.es/*
// @include http://es.stackoverflow.com/*
// @version 1.1
// @grant
// ==/UserScript==
document.body.style.zoom = "70%";
You can put as many lines of @include as you want to specify the pages where you will act. If you want me to act in all pon @include *://*/*
And below, set the% zoom% you need.
If you configure it in the browser by clicking on "Customize and control Google Chrome" - > Configuration, then click on "Show advanced configuration ..." and look for the part that says "Web Content", there you can change the zoom.
If you add the parameter --force-device-scale-factor=1.5 appears scaled to 1.5
Here you have a list with all the parameters that you can send:
