Guile/Cairo, files formats/surfaces

[Tomas By <tomas@basun.net>]

Hi all,

(Am following instructions on http://www.nongnu.org/guile-cairo/dev/)

I'm trying to create EPS files using guile-cairo, but have some 
problems. Am using version 1.14.2, the latest in Ubuntu.

scheme@(guile-user)> (cairo-version-string)
$1 = "1.14.2"

According to the web documentation at
http://www.nongnu.org/guile-cairo/docs/html/PostScript-Surfaces.html#PostScript-Surfaces
there should be a procedure `cairo-ps-surface-set-eps' to make the 
Postscript surface produce EPS, but this procedure is not defined:

scheme@(guile-user)> cairo-ps-surface-set-eps
;;; <unknown-location>: warning: possibly unbound variable 
`cairo-ps-surface-set-eps'

(It is not listed in /usr/share/guile/site/cairo/cairo-procedures.txt 
either, whatever that may mean.)

Also, the `recording' surface does not seem to be included in 
guile-cairo. Is there some reason for this? (other than lack of 
time/round tuits)

Finally, I am using SVG surfaces to make images which I then draw on PS 
surfaces and include in a Latex document. What surprises me is that the 
final pictures seem to be pixellated, not vector drawings. I am only 
using some simple Cairo commands (move to, line to, arc) to create the 
images. It seems to me that since SVG & PS/EPS are all vector formats 
there should not be any pixellation at all?

Grateful for any help in explaining this.
