NAME
       advpng - AdvanceCOMP PNG Compression Utility

SYNOPSIS
       advpng [-l, --list] [-z, --recompress] [-0, --shrink-0]
	    [-1, --shrink-fast] [-2, --shrink-normal [-3, --shrink-extra]
	    [-4, --shrink-insane] [-i, --iter N]
	    [-f, --force] [-q, --quiet]
	    [-h, --help] [-V, --version] FILES...
DESCRIPTION
       The  main purpose of this utility is to recompress png files to get the
       smallest possible size.

       Please note that this utility is not able to read a generic file.  It´s
       granted	to be able to read only the files generated by the AdvanceMAME
       emulator.

       To compress the files this utility uses the following strategies:
       ·      Remove all ancillary chunks.
       ·      Concatenate all the IDAT chunks.
       ·      Use the 7zip Deflate implementation.

OPTIONS
       -l, --list FILES...
	      List the content of the specified files.

       -z, --recompress FILES...
	      Recompress the specified files. If the -1, -2,  -3  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 compression.

       -0, --shrink-store
	      Disable  the  compression.  The file is only stored and not com‐
	      pressed. The file is always rewritten also if it´s bigger.

       -1, --shrink-fast
	      Set the compression level to "fast" using the zlib compressor.

       -2, --shrink-normal
	      Set the compression level to "normal" using the  7z  compressor.
	      This is the default level of compression.

       -3, --shrink-extra
	      Set  the	compression  level to "extra" using the 7z compressor.
	      You can define the compressor iterations	with  the  -i,	--iter
	      option.

       -4, --shrink-insane
	      Set  the compression level to "insane" using the zopfli compres‐
	      sor.  You can define the	compressor  iterations	with  the  -i,
	      --iter option.

       -i, --iter N
	      Define  an  additional numer of iterations for the 7z and zopfli
	      compressors for modes -3 and -4.	More iterations usually give a
	      better  compression,  but	 may require a lot more time.  Try for
	      example with 10, 15, 20, and so on.

       -f, --force
	      Force the use of the new file also if it´s bigger.
