.SH NAME

djvumake \- Assemble DjVu image files.

.SH SYNOPSIS

.BI "djvumake " "djvufile" " [" "chkid" "=" "argument" "]..." 

.SH DESCRIPTION

Program

.B djvumake

assembles a single-page DjVu file 

.I djvufile

by copying or creating chunks according to the provided arguments. 

Supported arguments are as follows:

.TP

.BI INFO= w , h , dpi

Create the initial information chunk.  Arguments 

.IR 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.

.TP

.BI Sjbz= jb2file

Create a 

.SM JB2 

foreground mask chunk.  File 

.I jb2file

may contain raw JB2 data, 

or be a DjVu file containing JB2 data

such as those produced by program

.BR cjb2 .

.TP

.BI Smmr= mmrfile

Create a

.SM MMR/G4 

foreground mask chunk.  File 

.I mmrfile

may contain raw MMR data or be a DjVu file 

containing MMR data.

.TP

.BI BG44= iw44file "[:" n "]"

Create one or more 

.SM IW44 

background chunks.  File 

.I iw44file 

must contain

.SM IW44 

data.

Such files can be obtained by compressing the background image

with program 

.B c44

and extracting the raw 

.SM IW44 

data using program

.BR djvuextract .

The optional argument

.I n

indicates the number of chunks to copy from the IW44 file.

Omitting the number of chunks copies all available chunks.

.TP

.BI BGjp= jpegfile

Create a 

.SM JPEG

encoded background chunk.

File 

.I jpegfile

must contain 

.SM JPEG 

encoded data.

.TP

.BI BG2k= jpegfile

Create a 

.SM JPEG-2000 

background chunk.

File

.I jpegfile

must contain 

.SM JPEG-2000

encoded data.

The DjVu decoder does not yet display

files containing JPEG-2000 data.

.TP

.BI FGbz=( filename |{# color [: x , y , w , h ]})

Create a foreground color chunk describing one solid

color for each

.SM JB2

encoded mark. 

The argument can be the name

.I filename

of a file containing the raw data.

Such files are best created using program

.BR djvuextract (1).

Alternatively the argument could describe a sequence of color zones.

Each color zone specifies a color name

.IR color ,

and optionally the coordinates

.IR 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. 

.BR FGbz=#FF8080 ,

or by one of the following sixteen HTML color names 

defined by the W3C, e.g.

.BR FGbz=#red .

.TP

.BI FG44= iw44file

Create a 

.SM IW44 

foreground color chunk.  

File 

.I iw44file 

must contain 

.SM IW44 

data.

Such files can be obtained by compressing the background image

with command 

.B c44

and extracting the raw 

.SM IW44 

data using program

.BR djvuextract .

Only the first chunk is copied.

.TP

.BI FGjp= jpegfile

Create a 

.SM JPEG

foreground color chunk.

.TP

.BI FG2k= jpegfile

Create a

.SM JPEG-2000

foreground color chunk.

The DjVu decoder does not yet display

files containing JPEG-2000 data.

.TP

.BI INCL= fileid

Create a DjVu3 include chunk pointing to the component file named 

.IR fileid .

The resulting file should then be included into a 

multipage document using command 

.BR djvm .

.TP

.BI Djbz= jb2file

Create a 

.SM JB2 

shape dictionary.  File 

.I jb2file

must contain raw JB2 data

describing a JB2 dictionary.

.TP 

.BI PPM= ppmfile

Create a

.SM IW44

background chunk and a 

.SM IW44 

foreground color chunk 

by masking and subsampling the 

.SM PPM

file

.IR ppmfile.

Assume, for instance, that we have a 

.SM PPM 

image 

.B myimage.ppm

and an identically sized

.SM PBM

bitonal image 

.B 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 

.SM PPM 

image. We can then produce a DjVuDocument image using the

following two commands:

.IP "" 3

.B cjb2 mymask.pbm mymask.djvu

.br

.B djvumake my.djvu Sjbz=mymask.djvu PPM=myimage.ppm

.br

.br

.PP

The DjVu specification documents in the directory

.B doc

of the DjVuLibre distribution provide the

authoritative information about the composition 

of a legal DjVu image file.
