```Dear Fellows: I´ve been working over this problem for a long time and
so far I haven't got the desired results. I need to create a linear
gradient (or at least simulate it) from left to right in a polygon. I
don't want to use metafun and the problem is how to fake it in eps. I
am in urgent need for a solution and I don´t have anyone to ask for
help excepto for this list. Could anybody help me please?
This is code I have so far:

path eme; % this is the polygon I need filled with a simulated
gradient from one color to another (horizontally).
eme = (-2.4u,6.2u)--(-4.5u,6.2u)--(-5.9u,0u)--(-4.15u,5.28u)--
(-5.25u,0u)--(-3.8u,4.389u)--(-3.7u,4.134u)--(-4.6u,0u)--(-3.45u,
3.485u)--(-3.30u,3.1u)--(-3.95u,0u)--(-3.15u,2.71u)--(-2.1u,0u)--
(0,0)--(0.81u,2.97u)--(2.0u,0u)--(4.10u,0u)--(1.7u,6.2u)--(-0.49u,
6.2u)--(-1.38u,3.58u)--cycle;
%%% Relleno
s := .1;
alt:= 6.2u;
lateral:= -6u;
for i=0 step s until 200:
fill eme shifted (-6u+i,0) withcmykcolor (i/100)[(1,0.60,.60,0),
(1,1,1,1)];
endfor;
endfig;
end;

Thanks a lot for you help.!!!
