Input IDAT size = 148494 bytes
Input file size = 148788 bytes

Trying:
  zc = 9  zm = 8  zs = 0  f = 0		IDAT size = 120990
  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 = 120990

Output IDAT size = 120990 bytes (27504 bytes decrease)
Output file size = 121068 bytes (27720 bytes = 18.63% decrease)
