In a custom draw function, I have this snippet:  
when the draw function is called, I can see the  
println messages printed on the REPL.  
But the Gtk window did not show the image from the svg file.

{ I also tried to comment out lines marked by # ?  
Still no image. }

What do I need to change in the code ?

thanks

ctx = Gtk.getgc(widget)

…  
r = Rsvg.handle\_new\_from\_file(“/Users/hpwei/julia/pieces/merida/w\_q.svg”)  
d = Rsvg.handle\_get\_dimensions(r)  
cs = Cairo.CairoImageSurface(d.width,d.height,Cairo.FORMAT\_ARGB32);  
c = Cairo.CairoContext(cs); # ?  
Rsvg.handle\_render\_cairo(c,r). # ?

```
println("svg width ", d.width). # this is ok
println("svg height ", d.height)

set_source_surface(ctx, cs, 0, 0) 
paint(ctx). # ?
fill(ctx)

```
