to-uint8  

Convert input array to uint8 array, detecting floats if required. Useful to ensure that an input array contains pixels/colors.


``js
var u8 = require('to-uint8')

var pixels = u8([[0,0,0,1], [1,1,1,1]]) //
`



u8data = u8(data, detectFloat=true)



Return Uint8Array u8data with input data values, possibly converted from floats, if required. data can be an Array, Array of Arrays, TypedArray, Buffer, ArrayBuffer, base64 string or any other container.

`js
u8(new Uint16Array([0, 1, 2])) //
u8(new Float32Array([0, .5, 1])) //
u8(new Float64Array([0, .5, 1])) //
u8([0, .5, 1]) //
u8([[0,0,0,0], [1,1,1,1]]) //

// untyped array with int-ish values doesn't get converted
u8([0, 1, 255]) //

// unless passed a flag to force conversion
u8([0, 1, 255], false) //

// bad data returns null
u8(/abc/) // null
``
