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  argu-
	      ments  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 pro-
	      duced 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 contain 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=(filename|{#color[:x,y,w,h]})
	      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 using 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 spec-
	      ified with exactly six hexadecimal digits, 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  |
							      +----------------------------------+
       FG44=iw44file
	      Create  a  IW44  foreground color chunk.	File iw44file must contain IW44 data.  Such files can be obtained by compressing the back-
	      ground 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  multi-
	      page document using command djvm.

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

       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

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