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=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 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.
- 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.
