[cairo] postscript?

[Charles Doutriaux]

Hello,

I'm going to try to simplify my problem as much possible

basically I'm drawing a LOT of little square with about 20 patterns.

I used to generate the pattern each and every time i would draw the 
square, which is much inefficient

A while ago somebody on the list suggested i only create the pattern 
once and then reuse it.

I finally got around doing this, but I still get the EXACt same 
postscript file. I'm not sure what I'm doing worng.

basically i limited calls to :
      pattern = cairo_pattern_create_for_surface (image);
      cairo_pattern_set_extend (pattern, CAIRO_EXTEND_REPEAT);
by saving pattenr
but i'm still calling:
          cairo_set_source(cr,pattern);
a gazillion times

Any idea why the postscript is still exactly the same?

I'm pasting an excerpt of  an example of the postscript output. i'll try 
to generate a small one next.

C.
