DESCRIPTION

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 isncqt changed. Only the compressed data is modified.

OPTIONS

-z, --recompress FILES...
Recompress the specified files. If the -1, -2, -3, -4 options are specified itcqs 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 compression.
-0, --shrink-store
Disable the compression. The file is only stored and not compressed. The file is always rewritten also if itcqs bigger.
-1, --shrink-fast
Set the compression level to a"fasta".
-2, --shrink-normal
Set the compression level to a"normala". This is the default level of compression.
-3, --shrink-extra
Set the compression level to a"extraa".
-4, --shrink-insane
Set the compression level to a"insanea". Itcqs VERY SLOW.
-f, --force
Force the use of the new file also if itcqs bigger.

LIMITATIONS

The advdef program cannot be used to recompress huge files because it needs to allocate memory for both the complete compressed and uncompressed data. This file is Copyright (C) 2003, 2004 Andrea Mazzoleni
