How to convert int[] to byte[]

Question

I have an array of integers which represent a RGB image and would like to convert it to a byte array and save it to a file.

What\'s the best way to convert an array

Answer 1

You need to decide how you convert 1 integer to a set of bytes first.

Most probably (?) 1 integer to 4 bytes, and use the shift (>> or <<) operators to get each byte out (watch that byte ordering!). Copy to a byte array 4 times the length of the integer array.
