# How can I have both onecolumn and twocolumn in the same page in ACM SIGPLAN paper

I need to have in the same page both onecolumn and twocolumn. As default, a page in ACM SIGPLAN latex is twocolumn. But I have a picture that need to be located in onecolumn. When I use : \onecolumn here picture \twocolumn ... My image will be put in a seprate page (alone). But I don't put it in a seprate page. I wonder if I have in the same page both onecolumn and twocolumn, i.e have that image at the top of the page in onecolumn, and the rest of that page contains ordinary text in two columnn.

Is it possible? SIGPLAN latex: http://drupal.sigplan.org/sites/default/files/sigplanconf-guide.pdf

This question came from our site for professional and enthusiast programmers.

It would be great if you could post a small mock-up of a document in the sigplanconf document class using lipsum and perhaps some images from mwe so that community members have something to work with. It will speed up the search for solution, surely. –  Werner Mar 6 '13 at 17:20

I think the trick might be to use the \begin{figure*}...\end{figure*} environment. That should give you a figure that spans the whole page width, while allowing the rest of that page to be in two columns. In contrast, the \begin{figure}...\end{figure} environment gives you a figure that spans only one column.
