DESCRIPTION

14       The  main  purpose of this utility is to recompress the data present in
15       the .png, .mng, .gz, .tgz and .svgz files.
16
17       The internal structure of the files isn’t changed.  Only the compressed
18       data is modified.

OPTIONS

21       ‐z, ‐‐recompress FILES...
22              Recompress  the  specified  files. If the ‐1, ‐2, ‐3, ‐4 options
23              are specified it’s used the smallest file choice from the previ‐
24              ous compressed data and the new compression. If the ‐0 option is
25              specified the file is always rewritten without any compression.
26
27       ‐0, ‐‐shrink‐store
28              Disable the compression. The file is only stored  and  not  com‐
29              pressed. The file is always rewritten also if it’s bigger.
30
31       ‐1, ‐‐shrink‐fast
32              Set the compression level to ˝fast˝.
33
34       ‐2, ‐‐shrink‐normal
35              Set the compression level to ˝normal˝. This is the default level
36              of compression.
37
38       ‐3, ‐‐shrink‐extra
39              Set the compression level to ˝extra˝.
40
41       ‐4, ‐‐shrink‐insane
42              Set the compression level to ˝insane˝. It’s VERY SLOW.
43
44       ‐f, ‐‐force
45              Force the use of the new file also if it’s bigger.
46

LIMITATIONS

48       The advdef program cannot be used to recompress huge files  because  it
49       needs  to  allocate  memory for both the complete compressed and uncom‐
50       pressed data.
