cairo:ps-surface-eps (surface)

surface -- a PostScript cairo:surface-t instance
eps -- true if the surface will output Encasulated PostScript

The cairo:ps-surface-eps function checks whether the PostScript surface will output Encapsulated PostScript. The (setf cairo:ps-surface-eps) function will set if the PostScript surface will ouput Encapsulated PostScript.

This function should only be called before any drawing operations have been performed on the current page. The simplest way to do this is to call this function immediately after creating the surface. An Encapsulated PostScript file should never contain more than one page.
