Input IDAT size = 15928 bytes
Input file size = 16018 bytes

Trying:
  zc = 9  zm = 8  zs = 0  f = 0		IDAT size = 12352
  zc = 9  zm = 8  zs = 1  f = 0
  zc = 1  zm = 8  zs = 2  f = 0
  zc = 9  zm = 8  zs = 3  f = 0
  zc = 9  zm = 8  zs = 0  f = 5
  zc = 9  zm = 8  zs = 1  f = 5
  zc = 1  zm = 8  zs = 2  f = 5
  zc = 9  zm = 8  zs = 3  f = 5
                               
Selecting parameters:
  zc = 9  zm = 8  zs = 0  f = 0		IDAT size = 12352

Output IDAT size = 12352 bytes (3576 bytes decrease)
Output file size = 12430 bytes (3588 bytes = 22.40% decrease)
