PROGRAM:

NAME


djvups - Convert DjVu documents to PostScript.

SYNOPSIS


djvups [options] [djvufile] [outputfile]

DESCRIPTION


This program decodes DjVu file djvufile, and generates a PostScript file named outputfile.
The DjVu data is read from the standard input when argument djvufile is not specified or
when it is equal to a single dash. Similarly, the output data is written to the standard
output when argument outputfile is not specified or equal to a single dash.

PostScript printers have various capabilities. Investigate options -level and -gray for
obtaining the best results.

OPTIONS


-help Prints the list of recognized options.

-verbose
Displays a progress bar.

-page=pagespec
Specify the document pages to be converted. The page specification pagespec
contains one or more comma-separated page ranges. A page range is either a page
number, or two page numbers separated by a dash. Specification 1-10, for instance,
prints pages 1 to 10. Specification 1,3,99999-4 prints pages 1 and 3, followed by
all the document pages in reverse order up to page 4.

-format=ps
Produce a PostScript file. This is the default.

-format=eps
Produce an Encapsulated PostScript file. Encapsulated PostScript files are
suitable for embedding images into other documents. Encapsulated PostScript file
can only contain a single page. Setting this option overrides the options -copies,
-orientation, -zoom, -cropmarks, and -booklet.

-copies=n
Specify the number of copies to print.

-orientation=orient
Specify whether pages should be printed using the auto, portrait, or landscape
orientation.

-mode=modespec
Specify how pages should be decoded. The default mode, color, renders all the
layers of the DjVu documents. Mode black only renders the foreground layer mask.
This mode does not work with DjVuPhoto images because these files have no
foreground layer mask. Modes foreground and background only render the foreground
layer or the background layer of a DjVuDocument image.

-zoom=zoomspec
Specify a zoom factor zoomspec. The default zoom factor, auto, scales the image to
fit the page. Argument zoomspec also can be a number in range 25 to 2400
representing a magnification percentage relative to the original size of the
document.

-frame=yesno
Specifying yes causes the generation of a thin gray border representing the
boundaries of the document pages. The default is no.

-cropmarks=yesno
Specifying yes causes the generation of crop marks indicating where pages should be
cut. The default is no.

-level=languagelevel
Select the language level of the generated PostScript. languagelevel. Valid
language levels are 1, 2, and 3. Level 3 produces the most compact and fast
printing PostScript files. Some of these files however require a very modern
printer. Level 2 is the default value. The generated PostScript files are almost
as compact and work with all but the oldest PostScript printers. Level 1 can be
used as a last resort option.

-color=yesno
The default value, yes, generates a color PostScript file. Specifying value no
converts the image to gray scale. The resulting PostScript file is smaller and
marginally more portable.

-gray This option is equivalent to option -color=no and is provided for convenience.

-colormatch=yesno
The default value, yes, generates a PostScript file using device independent colors
in compliance with the sRGB specification. Modern printers then produce colors
that match the original as well as possible. Specifying value no generates a
PostScript file using device dependent colors. This is sometimes useful with older
printers. You can then use option -gamma to tune the output colors.

-gamma=gammaspec
Specify a gamma correction factor for the device dependent PostScript colors.
Argument gammaspec must be in range 0.3 to 5.0. Gamma correction normally pertains
to cathodic screens only. It gets meaningful for printers because several models
interpret device dependent RGB colors by emulating the color response of a cathodic
tube.

-booklet=opt
Turns the booklet printing mode on. The booklet mode prints two pages on each side
in a way suitable for making a booklet by folding the sheets. Option opt can take
values no for disabling the booklet mode, yes for enabling the recto/verso booklet
mode, and recto or verso to print only one side of each sheet.

-bookletmax=max
Specifies the maximal number of pages per booklet. A single printout might then be
composed of several booklets. Argument max is rounded up to the next multiple of 4.
Specifying 0 sets no maximal number of pages and ensures that the printout will
produce a single booklet. This is the default.

-bookletalign=align
Specifies a positive or negative offset applied to the verso of each sheet.
Argument align is expressed in points (one point is 1/72th of an inch, or 0.352
millimeter) This is useful with certain printers to ensure that both recto and
verso are properly aligned. The default value is of course 0.

-bookletfold=base[+incr]
Specifies the extra margin left between both pages on a single sheet. The base
value base is expressed in points (one point is 1/72th of an inch, or 0.352
millimeter). This margin is incremented for each outer sheet by value incr
expressed in millipoints. The default value is 18+200.
