            [‐1, ‐‐shrink‐fast] [‐2, ‐‐shrink‐normal] [‐3, ‐‐shrink‐extra]

            [‐h, ‐‐help] [‐V, ‐‐version] FILES...


       The main purpose of this utility is to recompress the data present in the .png, .mng, .gz,
       .tgz and .svgz files.

       The internal structure of the files isn’t changed.  Only the compressed data is modified.


       ‐z, ‐‐recompress FILES...
              Recompress the specified files. If the ‐1, ‐2, ‐3, ‐4 options  are  specified  it’s
              used  the  smallest  file  choice  from  the  previous  compressed data and the new
              compression. If the ‐0 option is specified the file is always rewritten without any

       ‐0, ‐‐shrink‐store
              Disable  the  compression.  The file is only stored and not compressed. The file is
              always rewritten also if it’s bigger.

       ‐1, ‐‐shrink‐fast
              Set the compression level to ˝fast˝.

       ‐2, ‐‐shrink‐normal
              Set the compression level to ˝normal˝. This is the default level of compression.

       ‐3, ‐‐shrink‐extra
              Set the compression level to ˝extra˝.

       ‐4, ‐‐shrink‐insane
              Set the compression level to ˝insane˝. It’s VERY SLOW.

       ‐f, ‐‐force
              Force the use of the new file also if it’s bigger.


       The advdef program cannot be used to recompress huge files because it  needs  to  allocate
       memory for both the complete compressed and uncompressed data.
