DJVUMAKE(1)			 DjVuLibre-3.5			   DJVUMAKE(1)

NAME
       djvumake - Assemble DjVu image files.

SYNOPSIS
       djvumake djvufile [chkid=argument]...

DESCRIPTION
       Program	djvumake assembles a single-page DjVu file djvufile by copying
       or creating chunks according  to	 the  provided	arguments.   Supported
       arguments are as follows:

       INFO=w,h,dpi
	      Create  the  initial information chunk.  Arguments w, h, and dpi
	      describe the width, height and resolution	 of  the  image.   All
	      arguments	 may  be  omitted.  The default resolution is 300 dpi.
	      The default width and height will be retrieved  from  the	 first
	      mask chunk specified in the command line options.

       Sjbz=jb2file
	      Create  a	 JB2  foreground mask chunk.  File jb2file may contain
	      raw JB2 data, or be a DjVu file  containing  JB2	data  such  as
	      those produced by program cjb2.

       Smmr=mmrfile
	      Create a MMR/G4 foreground mask chunk.  File mmrfile may contain
	      raw MMR data or be a DjVu file containing MMR data.

       BG44=iw44file[:n]
	      Create one or more IW44 background chunks.  File	iw44file  must
	      contain  IW44  data.   Such files can be obtained by compressing
	      the background image with program c44  and  extracting  the  raw
	      IW44  data  using	 program djvuextract.  The optional argument n
	      indicates the number of chunks  to  copy	from  the  IW44	 file.
	      Omitting the number of chunks copies all available chunks.

       BGjp=jpegfile
	      Create a JPEG encoded background chunk.  File jpegfile must con‐
	      tain JPEG encoded data.

       BG2k=jpegfile
	      Create a JPEG-2000 background chunk.  File jpegfile must contain
	      JPEG-2000	 encoded  data.	 The DjVu decoder does not yet display
	      files containing JPEG-2000 data.

       FGbz=bzzfile
	      Create a foreground color chunk describing one solid  color  for
	      each JB2 encoded mark.  File bzzfile is best created by extract‐
	      ing the chunk data from an  existing  DjVu  file	using  command
	      djvuextract.

       FG44=iw44file
	      Create  a	 IW44 foreground color chunk.  File iw44file must con‐
	      tain IW44 data.  Such files can be obtained by  compressing  the
	      background  image	 with  command c44 and extracting the raw IW44
	      data using program djvuextract.  Only the first chunk is copied.

       FGjp=jpegfile
	      Create a JPEG foreground color chunk.

       FG2k=jpegfile
	      Create a JPEG-2000 foreground color  chunk.   The	 DjVu  decoder
	      does not yet display files containing JPEG-2000 data.

       INCL=fileid
	      Create  a	 DjVu3	include	 chunk	pointing to the component file
	      named fileid.  The resulting file should then be included into a
	      multipage document using command djvm.

       PPM=ppmfile
	      Create a IW44 background chunk and a IW44 foreground color chunk
	      by masking and subsampling the PPM file ppmfile.

	      Assume, for instance, that we have a PPM image  myimage.ppm  and
	      an  identically  sized  PBM bitonal image mymask.pbm whose black
	      pixels indicate which pixels belong to the foreground.   Such  a
	      bitonal  file might have been obtained by thresholding or color-
	      keying the PPM image. We can then produce a  DjVuDocument	 image
	      using the following two commands:

	  cjb2 mymask.pbm mymask.djvu
	  djvumake my.djvu Sjbz=mymask.djvu PPM=myimage.ppm

       Please	refer	to   the   DjVu	  specification	  (   http://www.djvu‐
       zone.org/djvu/djvu/djvuspec/ ) for more information about the  composi‐
       tion of a legal DjVu image file.
