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 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
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 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 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.
