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

       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.

       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.djvuzone.org/djvu/djvu/djvuspec/ ) for more information about the composition of a
       legal DjVu image file.
