       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
       arguments are as follows:

              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.

              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
              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 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.
