  Hi Tom,
  I am using the mini example below. Then in the generated pdf file the caption and the figure have too long separation. Please, suggest me some idea to reduce this distance.

  Regards,
  Humberto

  \documentclass{article}
  \usepackage{graphicx}
  \begin{document}
  \begin{figure}[!htp]
  \centering
  \includegraphics[viewport=-80 480 950 600, width=8in,height=5.0in,keepaspectratio]{Doc2.eps}
  \caption[Graph of the quadratic function]{Graph of the quadratic function $y=f(x)=\frac{\pi}{2}\sin{(\pi x)}$}\label{fig:graph1}
  \end{figure}
  \end{document}

    Hi Humberto!

    Wow, I didn’t know these includegraphics-options. Two things that I noticed with the set of options you use.

    1. viewport crops the image. The first two numbers indicate the part of the image that is removed from the bottom left corner. A negative number doesn’t make sense there.
    2. You use absolute width and height, and fix the aspect-ratio at the same time. Try either width or height and keepaspectratio or just width and height.

    To keep things simple, I suggest you use textwidth as a unit, it keeps the aspect-ratio. In case you need to crop your image, viewport is fine, but use positive numbers. Here is an example:

    \includegraphics[viewport=10 10 480 480, width=0.8\textwidth]{Doc2.eps}

    Hope it helps!

    Best, Tom.

  Hi Tom,
  Thanks for your suggestion. I tried it, but the separation between the graph and the caption increased. Can this problem be initiated with the creation of the eps file? I used a graph that was in pdf and I saved as eps file.

  Thanks,

  Humberto

    Hi Humberto,

    I’m so sorry, I just noticed that I forgot an important detail. You need to use the starred version of includegraphics to crop the image. Otherwise, it gets shifted, which is what you observe. Here is an example:

    \includegraphics*[viewport=0 0 100 100]{Doc2.eps}

    Thanks for your comment,
    Tom.

  Hi Tom,

  Thanks again, but with these commands only the captions appears, not the graph.

  \documentclass{article}
  \usepackage{graphicx}
  \begin{document}
  \begin{figure}[!htp]
  \centering
  \includegraphics*[viewport=0 0 100 100]{Doc2.eps}
  \caption[Graph of the quadratic function]{Graph of the quadratic function $y=f(x)=\frac{\pi}{2}\sin{(\pi x)}$}\label{fig:graph1}
  \end{figure}
  \end{document}

    Hey Humberto,

    Did you change the crop size? It may be that your figure is just white in the bottom-left 100x100pts. Best, Tom.

  Hi Tom

  Using the Window below, the starred version of includegraphics did not show the figure, however this command shows the figure with the large distance from the caption.

  \includegraphics[viewport=0 200 780 780]{Doc2}

  The figure was created using a testgenerator sofware and pasted in microsoft word, then I saved it as pdf file, and I transformed in an eps figure. You maybe right the figure is just white in the bottom-left. How much I need to crop it, such that I can get a reasonable distance between the figure and the caption?

    Hey Humberto,

    I’m not sure what your figure looks like, so I can’t really tell you much about the values you should use. However, you may want to try using bb instead of viewport. Apparently, viewport are the coordinates relative to the bounding box (bb) of the graph. See the graphicx guide for the definition.

    Your approach to get the eps-figure surprises me. Does your test-generator software not provide a way to export figures? If not, MS Paint may be a better choice than Word.

    Best, Tom.

  Thank you so much for your suggestions to fix my problem with the space between figures and the caption. I finally fixed it using the command trim in

  \includegraphics[trim =0in 7in 1in 0.2in, scale=.45]{graphs}

    Hey Humberto,

    Thanks for providing your solution. I actually wrote a post on the topic. I forgot to sent you a message, sorry.

    For the future, please try to find a post where your question fits best. You can use the search field on the right.

    Thanks, Tom.
