@deffn Function cairo-pdf-surface-create  (@var{width-in-points}@tie{}@code{<double>}) (@var{height-in-points}@tie{}@code{<double>}) [(@var{filename}@tie{}@code{<char>})] @result{}@tie{} (@var{ret}@tie{}@code{<cairo-surface-t >})
Creates a PDF surface of the specified size in points to be written to
@var{filename}. If @var{filename} is not given, the output is sent to
the current output port.


@table @var
@item filename
a filename for the PDF output (must be writable), @samp{@code{#f}} may
be used to specify no output. This will generate a PDF surface that may
be queried and used as a source, without generating a temporary file.

@item width-in-points
width of the surface, in points (1 point == 1/72.0 inch)

@item height-in-points
height of the surface, in points (1 point == 1/72.0 inch)

@item ret
a pointer to the newly created surface. The caller owns the surface and
should call @code{cairo-surface-destroy} when done with it. This
function always returns a valid pointer, but it will return a pointer to
a "nil" surface if an error such as out of memory occurs. You can use
@code{cairo-surface-status} to check for this.

@deffn Function cairo-pdf-get-versions  @result{}@tie{} (@var{versions}@tie{}@code{<cairo-pdf-version-t const*>}) (@var{num-versions}@tie{}@code{<int>})
Used to retrieve the list of supported versions. See
@code{cairo-pdf-surface-restrict-to-version}.

@table @var
@item versions
supported version list

@item num-versions
list length

@deffn Function cairo-pdf-surface-set-size  (@var{surface}@tie{}@code{<cairo-surface-t>}) (@var{width-in-points}@tie{}@code{<double>}) (@var{height-in-points}@tie{}@code{<double>})
Changes the size of a PDF surface for the current (and subsequent)
pages.

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 or immediately
after completing a page with either @code{cairo-show-page} or
@code{cairo-copy-page}.

@table @var
@item surface
a PDF @code{<cairo-surface-t>}

@item width-in-points
new surface width, in points (1 point == 1/72.0 inch)

@item height-in-points
new surface height, in points (1 point == 1/72.0 inch)
