Way to get each pixel RGBA values?

[w7rus]

Kinda confused what does .data contain in loaded object and how to use pixels() method.

I've ended up doing something like this because data was length of 4 * width * height, but that gave no positive result...

local data = testpnmg.load(pngContents)

local charArray = ffi.new("unsigned char[" .. #data.data .."]")
ffi.copy(charArray, data.data, #data.data)
for i=1, #data.data / 4 do
    print("R ", charArray[i], " G ", charArray[i + 1], " B ", charArray[i + 2], " A ", charArray[i + 3])
end
