I'm working with the IEEE conference teamplate on Overleaf, a two-collumn teamplate. I used the tool Diagram to draw figure and now I'm exporting the figure to pdf and then will import to the paper like this:

\begin{figure*}[ht!]
 \centering   \includegraphics[width=\textwidth]{figures/figure.pdf}
\end{figure*}

I know that with the option [width=\textwidth], the figure will be scaled to the width of current text. But with scaling, my figure seem to be a litte blur. Because the original width is different from the absolute value of \textwidth. My question is what is the absolute value of \textwidth? Or how to print it out in latex code?

Here, Diagram allows to export figure to the expected size, I'm not sure about the unit but I think 1346 here means 1346 pt: enter image description here

    Try \documentclass{article} \begin{document} \the\textwidth \end{document}. – Οὖτις Mar 08 '23 at 10:20
  • Note: \the\textwidth shows the width in pt=1/72.27". You can use package printlen to print in another unit, e.g., in bp=1/72" (usually used by other applications as point size). – cabohah Mar 08 '23 at 10:29

    I do not understand what you are trying to do here? What exactly did you create that you want to insert? And if it is a diagram, why is is not vector graphics? (aka resolution does not matter) – daleif Mar 08 '23 at 10:32

    note \begin{figure*}[ht!] is wrong, figure* does not have an h option, probably it should be \begin{figure*} so you also allow the figure to be full page. – David Carlisle Mar 08 '23 at 10:54

    If the figure seem blurred is because the PDF have not a vectorial draw, but a bitmap image like JPG photographs with not enough resolution (<300 ppp or so) or maybe is only an effect of the pdf viewer. Zoom at 400% or so. If it it is a vectorial draw, any part will look big, but perfect. If it is a bitmap, you will see the image clearly pixelated, and then the only solution is use a vectorial image or a bitmap with much more pixels. – Fran Mar 08 '23 at 12:03

Possibly the software produces a bitmap image although wrapping it in a PDF file, so scaling is not the best approach.

Since the IEEEtran class has a fixed value for \textwidth, you can see it by doing

\the\textwidth

in your document. This will print 516.0pt and all you need is to convert this into PostScript points: since there are 72.27pt in an inch, but only 72 PostScript points, you can compute with a calculator

>>> 516*72/72.27
514.07222914072229140722

and pass 514 for the width to the Diagram software. Then include your graphics with no scaling.
