I'm sure I've done this before but I can't remember how
So I have an RGBA bitmap that I've loaded into a variable tile image
Each value is the 32bit representation of a pixel
How can I convert it to the same format as you get from the pixels of costume reporter?
I feel there's a shortcut available to me somewhere to save me the trouble of decoding the integers
Here's what I would do. Convert the 32 bit to hex, then just convert that to rgba. Of course there's probably a much better way to do that though.
That's the sort of thing I'm trying to avoid the effort of doing 
Something in the back of my mind says there's an easy way to do this
RGBA mod 256 to get the lowest byte
RGBA = round( RGBA/256) to shift bytes
Repeat 4 times for 32bit 
Ta for that but it turns out my data isn't quite right - it's not actually integers 
It's sort of in bytes (but not quite!)
The data length should be exactly 520000 but it looks like some some of the byes are being returned as 16bit values - very strange - I need to work out what's going on!
I'm down a deep rabbit hole
I'm getting my data via my MQTT extension and it turns out that JavaScript fails to convert it cleanly and gets confused due to unicode
I'm off out for the evening so I'll have to look at it later!
I see nothing wrong with Chrome@Win10
When I google stuff, there seems to be problems with large arrays using that approach (as shown in my project)
The use of the spread operator ("..."), which simulates calling a proc with zillions of parameters, usually causes a problem.
But it seems that "typed array".toString() is skewed on your platform.
In this case toString() should return text "53,89,137..." without any unicode consideration.
I found this solution and it seems to work
With HOF in JS
result = payload.reduce( (res, val) => res+String.fromCharCode( val), "")
