ipack(1)		    General Commands Manual		      ipack(1)

NAME
       ipack - Manipulate Flex files containing	Shapes

SYNOPSIS
       ipack -c	SCRIPT

       ipack -x	SCRIPT

       ipack -u	SCRIPT

DESCRIPTION
       Flex  files  containing Shapes are used for the storage visual elements
       by the games Exult supports. While expack(1) can	operate	on such	files,
       using  ipack  is	 more comfortable. It can extract images from the Flex
       file directly into PNG-format, and create or update Flex	files  from  a
       list of PNG files.

       The first parameter determines the mode of operation:

       -c Creation
	      New Flex and palette files are created according to the instruc-
	      tions contained in the SCRIPT file.

       -u Update
	      Works like Creation, but updates an existing Flex	file.

       -x Extraction
	      The contents of the Flex file described in the SCRIPT  file  are
	      extracted	as PNG is dissected into its contents, as described in
	      this script file.

   Script File Format
       Empty lines, and	lines starting with a pound sign (#) are ignored.

       The names of the	associated Flex	archive	and palette files are given in
       lines containing	optional whitespace, one of the	tokens archive or pal-
       ette, whitespace, and the filename.

       Other lines define one shape each, and must begin with  an  image  slot
       number, followed	by a slash (/),	the number of frames, a	colon (:), and
       finally the PNG file specification.  The	numbers	may be given either in
       decimal,	 in octal prefixed with	0; or in hexadecimal prefixed with 0x.
       The file	specification consists of the filename PREFIX, optionally fol-
       lowed  by  a  number  and direction in brackets,	optionally followed by
       whitespace and the word flat.

       Per default, each shape corresponds to a	number of PNG files  (one  for
       each frame) named PREFIXnn.png with nn replaced by the frame number. If
       the optional bracket expression is used in the specification the	 Shape
       corresponds  to	a  single  PNG	file  instead.	This file contains all
       frames, each of which is	8 by 8 pixels in size, arranged	next  to  each
       other in	a rectangular grid. The	number in the bracket expression gives
       the size	of this	grid in	the direction indicated. The direction can  be
       either down or across.

EXAMPLES
       ipack -c	island.scr
	      Creates  a  Flex	file  and  a  palette file as specified	by is-
	      land.scr.

       ipack -x	island.scr
	      Extracts all components described	in island.scr  from  the  Flex
	      file given therein.

   Example script
       # script	file for island.flx
       archive island.flx
       # put the palette into this file
       palette island.pal
       # the zeroth image has 32 frames	in the files
       # zero00.png to zero31.png
       0/32:zero
       # image 5 consists of 22	frames stored in file
       # five.png in a grid 5 frames across (which means
       # 5 rows	of which the last holds	only 2 frames)
       5/22:five(5 across) flat
       # image 4 consists of 12	frames stored in file
       # four.png in a 3 by 4 grid
       4/12:four(4 down) flat
       # images	1 to 3 are unspecified

BUGS
       Tiled  Shapes  are  currently  extracted	into multiple PNG files, not a
       single file as expected during Create/Update.
