Removing pdf margins

 Today I was working under ESO proposals and I would include two  figure side by side, as esoform does not accept minipage I generate a pdf with the figures. But, then the problem start. It was necessary to remove the borders of the PDF file (figure I would insert). So I found the following text,  at: http://www.mobileread.com/forums/showthread.php?t=25331

By using the first example I was able to remove the borders of my figures page.

Many pdf files come for the printing, thus usually some large margins. But to read on Cybook you don't want margin, or do you? For me I just want as much space to display the text as possible.

I found one tool under linux. Very simple:

PDFCROP 1.5, 2004/06/24 - Copyright (c) 2002, 2004 by Heiko Oberdiek.
Syntax: pdfcrop [options] [output file]
Function: Margins are calculated and removed for each page in the file.
Options: (defaults)
--help print usage
--(no)verbose verbose printing (false)
--(no)debug debug informations (false)
--gscmd call of ghostscript (gs)
--pdftexcmd call of pdfTeX (pdftex)
--margins " " (0 0 0 0)
add extra margins, unit is bp. If only one number is
given, then it is used for all margins, in the case
of two numbers they are also used for right and bottom.
--(no)clip clipping support, if margins are set (false)
--(no)hires using `%%HiResBoundingBox' (false)
instead of `%%BoundingBox'
--papersize parameter for gs's -sPAPERSIZE=,
use only with older gs versions <7.32 ()
Examples:
pdfcrop --margins 10 input.pdf output.pdf
pdfcrop --margins '5 10 5 20' --clip input.pdf output.pdf

Truques em Latex - Comentar trechos de texto

Você já se deparou com um parágrafo de texto que gostaria de comentar? e precisa colocar o % em todas as linhas?

Há uma maneira muito prática de fazer isso:
Primeiro: 
Ative o pacote verbatim

\usepackage{verbatim} 

Depois é só fazer:

\begin{comment}
Este texto é legal.

Mas meu orientador não gostou.
Por isso tive que comentá-lo!
\end{comment}

Viram, muito fácil.
