[Tex/LaTex] Right angle symbols at corners of each page

paper-size

enter image description here

Why do some pdf files generated from LaTeX have those right angle symbols on the four corners of each page?
Do they mean to crop away the margins on top, bottom, left and right?

What is LaTeX code for implementing the symbols?

How can we crop away those surrounding margins for every page in such a pdf without its LaTeX code?

Thanks.

The actual paper size of the document in question is 8.5" x 11" (letter); the final format — as indicated by the crop marks — is 7" x 10" (504 x 720 bp). You have to cut .75" (54 bp) on the left and right and .5" (36 bp) on top and bottom.

You can trim the margins with pdfcrop.sh and the option -t "<left> [<top> [<right> <bottom>]]" :

$ ./pdfcrop.sh -t "54 36" input.pdf output.pdf

The result is a nicely trimmed 7" x 10" (504 x 720 bp) document:

bp = big point = postscript point = 1/72"

Paper Size – Print Two-Sided B5 Book on A4 Corners

Maybe you can use a4paper to specify the paper size, and manually play with margins? For example, if you are using B5, then the page width is 176mm. Assume you want 25.4mm margins on the page, this leaves 176 - (2 * 25.4) = 125.2mm width for text. The pagewidth is 250mm, so the total text height should be 250 - (2 * 25.4) = 199.2mm So you can set

\setlength{\textwidth}{125.2mm}
\setlength{\textheight}{199.2mm}

in the preamble. Now, A4 paper has width 210mm, so the difference is 210 - 176 = 34mm. You want the odd pages on top left, and even pages on the top right, so you set

\setlength{\oddsidemargin}{0mm}
\setlength{\evensidemargin}{34mm}
\setlength{\topmargin}{0mm}

(since 25.4mm is added to the values of \oddsidemargin, \evensidemargin, and \topmargin automatically). This should get you what you want.

[Tex/LaTex] How to specify a very long page

You can solve both problems by using the paperwidth and paperheight options geometry provides instead of setting the values "manually" with \setlength:

\documentclass{article}
\usepackage[left=10px,right=10px,top=10px,bottom=10px,paperwidth=8in,paperheight=33in]{geometry}

\usepackage{lipsum}
\newsavebox\widgetbox
\begin{document}

\setbox\widgetbox\vbox
  {\vspace*{6pt}\noindent Type of Widget: \dotfill \break
  Observations: \dotfill \break
  \null\dotfill\par}

\lipsum[1]

\cleaders\copy\widgetbox\vskip0pt plus 1fill
\end{document}
