How to get Retina (x2) screenshots?

[bertelli]

I'm using this script and it's awesome, but I don't understand how to get Retina (x2) screenshots?

Currently puppetron doesn't generate retina screenshots. It's on purpose because the large screenshots seems to crash the chrome instance which I haven't figure out how to fix.

If you use puppeteer directly, you could set it via setViewport with deviceScaleFactor setting: https://github.com/GoogleChrome/puppeteer/blob/master/docs/api.md#pagesetviewportviewport

Thank you! so what's the main difference and advantage of using Puppertron vs Puppeteer? Thanks again! Great work!

Puppeteer is a low-level JavaScript library to control headless Chrome with specific API methods.

Puppetron uses Puppeteer and provides a web interface to demonstrate some of its features.

So by right, Puppetron is not meant to be used to do anything serious, it's just a demo site or proof-of-concept of what Puppeteer can do. It's pretty similar to another demo site made by other Google devs: https://try-puppeteer.appspot.com/

If you just want to manually generate random screenshots (or html or pdf) of sites, feel free to use Puppetron site/script. If you want to do some sort of automation and using it as a service for your site, it's better to write your own using Puppeteer to suit your specific use-cases or use 3rd-party services, for example Screen.rip.
