11
14 Program djvumake assembles a single-page DjVu file djvufile by copying
15 or creating chunks according to the provided arguments. Supported
16 arguments are as follows:
17 INFO=w,h,dpi
19 Create the initial information chunk. Arguments w, h, and dpi
20 describe the width, height and resolution of the image. All
21 arguments may be omitted. The default resolution is 300 dpi.
22 The default width and height will be retrieved from the first
23 mask chunk specified in the command line options.
24 Sjbz=jb2file
26 Create a JB2 foreground mask chunk. File jb2file may contain
27 raw JB2 data, or be a DjVu file containing JB2 data such as
28 those produced by program cjb2.
29 Smmr=mmrfile
31 Create a MMR/G4 foreground mask chunk. File mmrfile may contain
32 raw MMR data or be a DjVu file containing MMR data.
33 BG44=iw44file[:n]
35 Create one or more IW44 background chunks. File iw44file must
36 contain IW44 data. Such files can be obtained by compressing
37 the background image with program c44 and extracting the raw
38 IW44 data using program djvuextract. The optional argument n
39 indicates the number of chunks to copy from the IW44 file.
40 Omitting the number of chunks copies all available chunks.
41 BGjp=jpegfile
43 Create a JPEG encoded background chunk. File jpegfile must con‐
44 tain JPEG encoded data.
45 BG2k=jpegfile
47 Create a JPEG-2000 background chunk. File jpegfile must contain
48 JPEG-2000 encoded data. The DjVu decoder does not yet display
49 files containing JPEG-2000 data.
50 FGbz=(filename|{#color[:x,y,w,h]})
52 Create a foreground color chunk describing one solid color for
53 each JB2 encoded mark. The argument can be the name filename of
54 a file containing the raw data. Such files are best created
55 using program djvuextract(1). Alternatively the argument could
56 describe a sequence of color zones. Each color zone specifies a
57 color name color, and optionally the coordinates x,y,w,h of a
58 rectangle. Each mark receives the color of the last color zone
59 whose rectangle intersects the bounding box of the mark. The
60 mark is painted black if its bounding box does not intersect one
61 of the zones. The rectangle coordinates are expressed in pixels
62 with the origin at the bottom left corner of the page. The full
63 page is assumed when no rectangle coordinates are specified.
64 Color names can be specified with exactly six hexadecimal dig‐
65 its, e.g. FGbz=#FF8080, or by one of the following sixteen HTML
66 color names defined by the W3C, e.g. FGbz=#red.
67 ┌──────────────────────────────────┐
69 │aqua black blue fuchsia │
70 │gray green lime maroon │
71 │navy olive purple red │
72 │silver teal white yellow │
73 └──────────────────────────────────┘
74 FG44=iw44file
75 Create a IW44 foreground color chunk. File iw44file must con‐
76 tain IW44 data. Such files can be obtained by compressing the
77 background image with command c44 and extracting the raw IW44
78 data using program djvuextract. Only the first chunk is copied.
79 FGjp=jpegfile
81 Create a JPEG foreground color chunk.
82 FG2k=jpegfile
84 Create a JPEG-2000 foreground color chunk. The DjVu decoder
85 does not yet display files containing JPEG-2000 data.
86 INCL=fileid
88 Create a DjVu3 include chunk pointing to the component file
89 named fileid. The resulting file should then be included into a
90 multipage document using command djvm.
91 Djbz=jb2file
93 Create a JB2 shape dictionary. File jb2file must contain raw
94 JB2 data describing a JB2 dictionary.
95 PPM=ppmfile
97 Create a IW44 background chunk and a IW44 foreground color chunk
98 by masking and subsampling the PPM file ppmfile.
99 Assume, for instance, that we have a PPM image myimage.ppm and
101 an identically sized PBM bitonal image mymask.pbm whose black
102 pixels indicate which pixels belong to the foreground. Such a
103 bitonal file might have been obtained by thresholding or color-
104 keying the PPM image. We can then produce a DjVuDocument image
105 using the following two commands:
106 cjb2 mymask.pbm mymask.djvu
108 djvumake my.djvu Sjbz=mymask.djvu PPM=myimage.ppm
109 The DjVu specification documents in the directory doc of the DjVuLibre
111 distribution provide the authoritative information about the composi‐
112 tion of a legal DjVu image file.
