I have the following data from a photoshop file that uses zip-compression (RFC1951):
250, 255, 159, 1, 47, 248, 63, 42, 63, 172, 229, 1, 2, 12, 0, 209, 255, 31, 225
Which decompresses to the following, x16:
255, 255, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
Re-compressing this gives me:
251, 255, 159, 1, 47, 248, 63, 42, 63, 172, 229, 1
Why isn't this exactly the same as the original input?
