Apps Script v8: ArrayBuffers and Typed Arrays

[Bruce Mcpherson]

Apps Script V8 implements ArrayBuffers and Typed arrays from ES6. If you’ve used Apps Script Crypto Utilities or done any work with Blobs, then this is what’s going on behind the scenes, now exposed as part of the language.

Thanks Bruce.

Have you tried to manipulate images thanks to that? (eg: resize / compress an existing image)

[Bruce Mcpherson]

Hi Romain

No I haven't tried that. This is something I do a lot in Node, but for that there are a number of packages for manipulating images. I may have a look at the details if I get some time.

cheers

Great, if you are already familiar with existing packages for Node it would be interesting to see how easy / possible it is to reuse them in Apps Script.

I know several people in the past were interested by easy image manipulation directly in Apps Script (eg: to resize a bunch of images stored in Drive)

To be honest I have seen javascript code doing that with blobs (as bytearrays), in apps script, in the past...?

Thank you for the information. From the information, I could know that Google Apps Script can become more affinity to Javascript when the binary data is processed. Also I would like to measure the process cost for this.

[Bruce Mcpherson]

Yes, you could fiddle around with byte arrays in legacy apps script, but the mapping variables that spread over multiple bytes back to actual numbers is now solved with the Typed Arrays
