I have come across this code here(How to manipulate an externally-generated pdf figure in LateX?) that allows me to send some labels/annotations to an image in a pdf file. The pdf file is already cropped but when I compile it, I see the pdf file as a whole A4 paper with a number in the bottom.

Here is the code:

\documentclass{article}

\usepackage{graphicx}

\begin{document}


\begin{picture}(0,0)%
  \put(0,0){\includegraphics[width=.4\textwidth]{Telescope_Lens.pdf}}%

\end{picture}%

\end{document}

This is the original image in the pdf file (notice how the image is cropped): enter image description here

And this is the image i get when I compile (Notice the page number and how long the image has become): enter image description here

Any idea what is happening here? Many thanks

  • Erh, you're explicitly setting the width of the inserted image, so your second image looks like how I'd expect it

    Welcome to TEX StackExchange! Standard article class use letter paper in page size. According to your setting width=.4\textwidth, the image is displayed properly. This is the way how it will be shown in the page. What is your expected result?

  • Thank you @Tom for the reply. I am expecting an image exactly like the first image. I just did not understand why there is a page number in the bottom while my first image is cropped and ready for annotations. My purpose was to send some annotations/labels to the image but ended up with this long A4-type page! May 10, 2022 at 6:18
  • The article class will do that for you: it inserts your image into a full-size sheet of paper. Perhaps some other class (standalone ?) might be more appropriate. Of course everything depends upon your final goal.

    You could probably use \documentclass{standalone} and package tikz to achieve that.

The \documentclass{standalone} and package tikz will do the job.

Thank you both.
