Hi Aditya,
I’m trying to include my additions into your code, but it doesn’t work.
numeric sketch_amount; sketch_amount := 3bp;
numeric sketch_passes; sketch_passes := 5;
def sketchdraw expr p =
do_sketchdraw(p if (path p): randomized sketch_amount fi)
enddef;
def do_sketchdraw(expr p) text t =
normaldraw p t ;
enddef;
Now I want to draw that path several times.
If I understand it right, I can’t put that into "sketchdraw" because that
leaves the end open for path additions like "withcolor".
But it also doesn’t work in "do_sketchdraw"; I thought it might like this:
def do_sketchdraw(expr p) text t =
for i=0 upto sketch_passes :
normaldraw p t ;
% withtransparency ("multiply", 1/sketch_passes) ; % and how can I add
that without breaking other additions?
endfor
enddef;
But that just blocks, I guess there’s an infinite loop.
I’d be happy about some advise.
