# [Tex/LaTex] How to make images appear at their actual size

graphicspdftex

Whenever I insert an image into my PDFTex document (using the code below) it seems to be resized to fit the width of the page. I know I can change this using the scale parameter, but that means I have to play with the scaling factor until it comes out roughly the size I actually created it.

\begin{center}
\includegraphics[scale=0.75]{ikonos.png}
\end{center}


Is there a way to display an image without scaling it to the width of the page?

Be warned, however, that .png files often don't include the correct information on resolution. This will lead pdfTeX to insert them as 72 dpi images, which may not be desirable. See other questions on apparently 'blocky' images, for example.
