[Tex/LaTex] Centering image around center of page

graphics

Is there an option to align the center of an image with the centre of a page?

Background: essentially I have got an image that has got some white stuff left and right, while top and bottom is fine as it is. I don't want to crop it, so I thought I could just overscale it slight so that the white stuff falls beyond the margin of the page. But when using \centering or \begin{center} ... \end{center} I could not achieve the required result since the figure looks like it is bounded by the left margin. Maybe I put the commands in the wrong place though (e.g. should I put it around the figure or around the \includegraphics)

Any help appreciated!

You can use a \makebox if you want the graphics to stick out on both sides:

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{graphicx,lipsum}
\begin{document}
\lipsum[1]

\centering
\makebox[\linewidth]{\includegraphics[width=1.5\linewidth]{example-image}}
\end{document}

[Tex/LaTex] Change float background colour

Looking at the color documentation, it says that \colorbox uses the parameters \fboxrule and \fboxsep. Maybe try

\setlength\fboxrule{0pt}
\setlength\fboxsep{0pt}

before using the \colorbox.

Edit:
It seems to work for me. The space between the rules isn't added by the \colorbox, but by the ruled float style. One possibility would be to design a new float style and then use \restylefloat from the float package to change the style of the algorithm floats. Rather than do that, I just added some kerns.

I'm becoming less and less convinced this is the right way to do these things. It feels like we're just piling hack on top of hack here. I feel like this is partly due to using LyX, but I have zero experience with it, so I'm not positive.

[Tex/LaTex] How to center large figures in LaTeX and how to fix short justified lines

\centerline{\includegraphics{foo}}
Can you provide an example? You can use \raggedright or even ragged2e package to control the paragraph. However, I wonder how the short lines fill the whole page width.
