- DviDvi converts a DVI-file into another DVI-file. This is version
- 1.0, author Thomas Rockicki, Amiga-Port (better: PasTeX-Port) Jochen
- Wiedmann. Copyright (C) 1988-91, Radical Eye Software
-
- Here's a little hack I threw together for those doing pagination
- tricks. The dvidvi program converts a DVI file into another DVI file,
- with perhaps certain changes.
-
- Enjoy; this is an early release, so make suggestions, improvements,
- and I'll get back to you with a better version later.
-
- Invocation: Parameters, options and arguments
- *********************************************
-
- Invocation is
-
- dvidvi param infile outfile
-
- What are the parameters? The 'easy' parameters are the following:
-
- -f n
- page n is first page selected
-
- -l n
- page n is last page selected
-
- -n n
- select at most n pages. Notice that n is the number of pages
- selected, independently of the number of pages actually contained
- in a sheet
-
- -i { n1..n2 | n1 }[,...]
- include pages (ranges allowed). When this option is used, ONLY the
- specified pages are selected. However, we can exclude from these
- pages with the option -x
-
- -x { n1..n2 | n1 }[,...]
- exclude pages (ranges allowed)
-
- -q
- work in quiet mode, that is do not print in the screen messages of
- how the work is being done.
-
- -r
- reverse the order of the pages.
-
- -sm m
- Scale the magnification. (Magnification is multiplied by
- magstep(m)).
-
- -sh m
- Scale the document-height. (Height is multiplied by magstep(m)).
-
- -sw m
- Scale the document-width. (Width is multiplied by magstep(m)).
-
- The page numbers for the above options -f, -l, -i and -x can
- be specified in different ways.
-
- 1. If a number n is given, it is interpreted as the n'th page from the
- begining of the .dvi file. Of course, this number is independent
- of the page number assigned by TeX.
-
- 2. TeX page numbers are those who are actually written in the page;
- these page numbers can be modified, for example, by using the TeX
- commands \pagenumbering, \setcounter{page}{n}, and
- \addtocounter{page}{n}. A TeX page number can be specified
- by preceding the number n with the character @. Thus, if you
- specify -f @25 -l @30 you select the pages between 25 and 30,
- these numbers being those assigned by TeX.
-
- 3. However, several pages can have the same TeX page number in a .dvi
- file. For example, the introductory pages in a book are numbered
- i, ii, and so on until the first chapter begins and then, the
- pages are numbered 1, 2, etc. In this case, the pages numbered i
- and 1 in the .dvi file have the same TeX page number. If you want
- to select for example the second occurrence of the page numbered
- 1, you can specify a page number as (@2)1. Thus @1 is equivalent
- to (@1)1. For example, if you specify -f (@2)1 -l(@2)10 you
- select the pages between 1 and 10 of the first chapter, not the
- introductory pages between i and x.
-
- There is another parameter that tells DviDvi how you want to change
- page layout and specifications. But this parameter is somewhat
- complicated and therefore explained in a special section. See Examples.
-
- Examples (the -m-parameter)
- ***************************
-
- There is another parameter that tells dvidvi how you want to change
- page layout and specifications. This is the -m parameter.
-
- The number preceding the colon is the modulo value. Everything will
- be done in chunks of pages this big. If there is no colon, than the
- default value is assumed to be one. The last chunk of pages is padded
- with as many blank pages as necessary.
-
- Following the colon is a comma-separated list of page numbers.
- These page numbers are with respect to the current chunk of pages, and
- must lie in the range zero to the modulo value less one. If a negative
- sign precedes the number, then the page is taken from the mirror chunk;
- if there are m chunks, then the mirror chunk of chunk n is the chunk
- numbered m-n-1. Put simply, it is the chunk numbered the same, only
- from the end. This can be used to reverse pages. If no number is
- given, the page number defaults to 1.
-
- Following each page number is an optional offset value in
- parenthesis, which consists of a pair of comma-separated dimensions.
- Each dimension is a decimal number with an optional unit of measure.
- The default unit of measure is inches, or the last unit of measure
- used. All units are in true dimensions. Allowable units of measure
- are the same that TeX allows: in, mm, cm, pt, pc, dd and
- cc.
-
- Simple enough, eh? Okay, let's do some simple things.
-
- -m -
- Reverses the order of the pages. This time, both the modulo and
- the page number are defaulted.
-
- -m 2:0
- Selects the first, third, fifth, etc. pages from the file. Print
- this one after printing the next, taking the paper out of the feed
- tray and reinserting it into the paper feed.
-
- -m 2:-1
- Selects the second, fourth, etc. pages, and writes them in reverse
- order.
-
- -m 4:-1,2(4.25in,0in)
- -m 4:-3,0(4.25in,0in)
- Useful for printing a little booklet, four pages to a sheet,
- double-sided, for stapling in the middle. Print the first one,
- put the stack back into the printer upside down, and print the
- second. The `in' specifications are superfluous.
-
- -m ,(1pt,1)
- Scare your system administrator! Actually, things are so blurry
- with this option, you may want to send enemies letters printed
- like this. *Long* letters.
-
- -m 4:0(5.5in,4.25),3(0,4.25)
- -m 4:1(0in,4.25),2(5.5,4.25)
- Print a four-page card on one sheet. Print the first, rotate the
- paper 180 degrees and feed it again. (PostScript people can do
- funny tricks with PostScript so this isn't necessary.)
-
- Installing and using DviDvi with DviPS
- **************************************
-
- Installation isn't very hard: Just copy the program to a place
- contained in your search-path.
-
- Note that you don't need the parameters -sm, -sw and -sh with
- DviPS: The document-width and -height are simply ignored by Dvips and
- the magnification can be changed with the -x parameter.
-
- A little example might help, which prints a DVI file with two pages
- per sheet of paper:
-
- dvidvi -m 2:0,1(7.3,0.0) infile.dvi outfile.dvi
-
- dvips -x 694 outfile.dvi
-
- Note that the -x-parameter divides the magnification by magstep(2),
- because 694 equals to 1000 divided by 1.44 (magstep(2)).
-
- Installing and using DviDvi with PasTeX
- ***************************************
-
- Things are a little bit more complicated using PasTeX. This is
- because PasTeX (ShowDVI and DVIprint, to be a little more precise) uses
- the informations about document-width and height contained in the DVI
- file to determine the size of RAM that is needed. Further it isn't
- possible to scale the magnification in a device-independent way. (For
- example you need to divide the number 180 by magstep(2) when printing
- on a Nec-P6 in draft-mode instead of the device-independent number 1000
- from the example above.)
-
- DviDvi satisfies our needs with the options -sm, -sw and
- -sh here. The example above would look here as follows:
-
- dvidvi -m 2:0(0.0,-0.75),1(7.3,-0.75) -sm -2 -sw 4 infile.dvi
- outfile.dvi
-
- dviprint landscape on outfile.dvi
-
- Installing looks nearly the same as installing DviDvi for DviPS
- (Simply copy the program to whereever you want), except that the
- automatical font-generation needs to get a little bit enhanced. (We
- need to support magstep(-4) up to magstep(9) now instead of magstep(0)
- up to magstep(9).) This is done by removing replacing the original file
- MakeTeXFont.rexx with the file PasTeX/MakeTeXFont.rexx from the
- DviDvi-distribution.

- Contacting Thomas Rockicki
- **************************
-
- I (Jochen Wiedmann for now) am very sorry, that i don't know Thomas
- Rockicki's address, especially because of his friendly invitation to
- make suggestions about the program. All i found was an old
- Internet-address in Georg Hessmann's dvips-distribution. I don't know
- if it's still valid, but here it is:
-
- rockicki@neon.stanford.edu
-
- You can contact me as well, if you have problems concerning the
- Amiga-port. I don't know if i can help (all i know about DVI files was
- what i learned in the last three hours), but i'll try. Here's how you
- reach me:
