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 pro-
       vided 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 contain-
              ing 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 specified 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 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.

       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 composition of a legal DjVu image file.
