Extend a figure 100% horizontally with a fixed height in LaTeX?

Question

How can I insert a figure (i.e. graphic) that extends 100% of the viewport but with a given height?

Answer 1

You can use the usual [width=X,height=Y] parameters, but instead of giving a literal X use \columnwidth...

If you want the figure to span multiple columns, use \begin{figure*} instead of \begin{Figure}
