       djvumake	- Assemble DjVu	image files.

       djvumake	djvufile [chkid=argument]...

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

	      Create  the  initial information chunk.  Arguments w, h, and dpi
	      describe the width, height and resolution	of the image.  All ar-
	      guments 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.

	      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.

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

	      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.

	      Create a JPEG encoded background chunk.  File jpegfile must con-
	      tain JPEG	encoded	data.

	      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.

	      Create a foreground color	chunk describing one solid  color  for
	      each JB2 encoded mark.  The argument can be the name filename of
	      a	file containing	the raw	data.  Such files are best created us-
	      ing  program  djvuextract(1).   Alternatively the	argument could
	      describe a sequence of color zones.  Each	color zone specifies a
	      color  name  color,  and optionally the coordinates x,y,w,h of a
	      rectangle.  Each mark receives the color of the last color  zone
	      whose  rectangle	intersects  the	bounding box of	the mark.  The
	      mark is painted black if its bounding box	does not intersect one
	      of the zones.  The rectangle coordinates are expressed in	pixels
	      with the origin at the bottom left corner	of the page.  The full
	      page  is	assumed	 when  no rectangle coordinates	are specified.
	      Color names can be specified with	exactly	six  hexadecimal  dig-
	      its, e.g.	 FGbz=#FF8080, or by one of the	following sixteen HTML
	      color names defined by the W3C, e.g.  FGbz=#red.

			    |aqua     black   blue     fuchsia |
			    |gray     green   lime     maroon  |
			    |navy     olive   purple   red     |
			    |silver   teal    white    yellow  |
	      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.

	      Create a JPEG foreground color chunk.

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

	      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.

	      Create a JB2 shape dictionary.  File jb2file  must  contain  raw
	      JB2 data describing a JB2	dictionary.

	      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

       The  DjVu specification documents in the	directory doc of the DjVuLibre
       distribution provide the	authoritative information about	 the  composi-
       tion of a legal DjVu image file.

       This  program  was written by Leon Bottou <>
       and was then improved  by  Andrei  Erofeev  <>,
       Bill Riemers <> and many others.
