when using dashes and patterns the putput "freaks" out for lines!
This is postscript only, cairo works great with png for example
I'm pasting a small C example, turn on/off any of do32, dodashes or dopattern
ude <cairo.h>
#include <cairo-ps.h>

int ndashes;
double offset=0.;
 dashes[0]=8.;
 dashes[1]=4.;
 dashes[2]=4.;
 dashes[3]=4.;
 ndashes = 4;

   if (do32) image = cairo_image_surface_create(CAIRO_FORMAT_ARGB32,4,4);
   else image = cairo_image_surface_create(CAIRO_FORMAT_RGB24,4,4);
   cr2 = cairo_create (image);
   cairo_set_source(cr2,cairo_get_source(cr));
   cairo_move_to(cr2,0,0);
