更改 {pdf-,Xe-}TeX 中的頁邊距

Question

在 TeX 中，變更\hsize和 會\vsize變更主文字大小和 dvi 輸出的頁面大小。當我使用 pdftex 或 xetex 編譯文件時，頁面大小仍為 A4。如何更改頁邊距？

最小的例子：

\hsize=5cm \vsize=4cm
\footline{\hfil The page ends here!\hfil\the\pageno}
This document leaves much white space when {\tt pdftex\/}ed or {\tt xetex\/}ed.

Answer 1

{Lua-,pdf-,Xe-}TeX 的解

\hsize=2in \vsize=3in
\pdfpagewidth=4in
\pdfpageheight=5in
\footline{\hfil The page ends here!\hfil\the\pageno}
This document is by far better! Notice that \TeX{} starts every page
one inch away from the upper and left margin.
This example doesn't compile with {\tt tex} anymore.
