love.math.colorFromBytes

 Available since LÖVE 11.3 This function is not supported in earlier versions.

Converts a color from 0..255 to 0..1 range.

Function

Synopsis

`r, g, b, a = love.math.colorFromBytes( rb, gb, bb, ab )`

Arguments

`number rb`
Red color component in 0..255 range.
`number gb`
Green color component in 0..255 range.
`number bb`
Blue color component in 0..255 range.
`number ab (nil)`
Alpha color component in 0..255 range.

Returns

`number r`
Red color component in 0..1 range.
`number g`
Green color component in 0..1 range.
`number b`
Blue color component in 0..1 range.
`number a (nil)`
Alpha color component in 0..1 range or nil if alpha is not specified.

Notes

Here's implementation for 11.2 and earlier.

```function love.math.colorFromBytes(r, g, b, a)
if type(r) == "table" then
r, g, b, a = r[1], r[2], r[3], r[4]
end
r = clamp01(floor(r + 0.5) / 255)
g = clamp01(floor(g + 0.5) / 255)
b = clamp01(floor(b + 0.5) / 255)
a = a ~= nil and clamp01(floor(a + 0.5) / 255) or nil
return r, g, b, a
end```

Where `clamp01` is defined as follows

```local function clamp01(x)
return math.min(math.max(x, 0), 1)
end```
