[Tex/LaTex] Include figure from PDF file

graphicsincludepdfpdfpages

I want to include a figure from another PDF.

There is the quick way, where I take a screen shot, save as my desired format and the \includegraphics[scale=xx]{<file path>} but this is messing up the scaling, want the text size in the image to match the text size of my document.

I'm condering using \includepdf[pages=x,trim= l r b t,clip]{<file path>}.

I'd like to know, in general, if there is a smarter way.

Example

I want to include a chart from a user manuel usemanual.pdf showing relations between variables when defining a input grid for a computational model, in my document Thesis.tex

Best Answer

graphicx is able to add only one page from a PDF file and to trim it.

\documentclass{article}
\usepackage{graphicx}
\begin{document}
Some text

\includegraphics[
  page=15,
  trim=14.8cm 5cm 1cm 21cm,
  clip
]{../calcolo/trigonometria/trigonometria.pdf}

Some other text

\end{document}

This is the original page:

Some trial and error in determining the amount of trimming will solve the problem.
