Recently, I had been looking for creating an image from coordinate data. Unfortunately I have never found them. So I made this. This Google Apps Script (GAS) library creates an image file from coordinate data.
You can see the detail information at https://github.com/tanaikech/CreateImg.
There is a part where I would like to improve in this library. That’s convByteSlice(). I think that there is the method to be faster about the part. If you know much about the logical operation using GAS, if you teach me about the improvements. I’m so glad.
