Patch for pdftex and magnification
To fix an incompatibility in tetex,
download the package pdftexpatch.tar.gz. Untar it; enter the
directory; become root; run pdftexinipatch.sh.
It will adjust the formats for pdftex so that \magnification
will work compatibly when producing pdf output.
Modern usage of TeX often bypasses the dvi stage by using pdftex to
produce pdf format output. In fact this is rapidly becoming
standard. Unfortunately the authors of pdftex have adopted policies
for defining the size of the text region that lead to
incompatibilities in TeX processing when producing pdf. The error
occurs when pdftex encounters a \magnification command.
In TeX (using the Plain macros) the \magnification is
frequently used to produce text size that is readable. It scales
everything up within the normal paper size. However, when producing
pdf (but not when producing dvi), pdftex fails to do this scaling
correctly, because it relies on different variables for its vsize,
voffset etc. I have had a long discussion (read argument) with the
authors of pdftex. They do not consider this erroneous behavior to be
worth fixing. Or at least they have so far refused to fix it.
Actually there is something of a demarcation problem in that the fix
that is offered here is applied to the file pdftex.ini. That file is
considered by some to be the responsibility of the TeX distribution
rather than the programmers of pdftex. The distribution tetex, which
is what linux distributions have used for a long time, is now not
actively being developed. Therefore it does not seem possible to
persuade anyone to patch the system to correct this incompatibility.
That is why the present script is being distributed. If you have
problems with plain TeX files, \magnification, and pdftex
producing pdf, you can use the package to correct your tetex system so
that it will do correct scaling. It works automatically (on standard
