Hi, I would like to obtain, if possible, a gray gradient like in the image. My code uses Metapost but maybe this is possible with Metafun. Thanks. Fabrice \starttext \startMPcode u=1.2cm; interim ahangle := 30; z0=(0,0); z1=(3u,0); z2=(3u,4u); z3=(0,4u); z4=(0.8u,4u); z5=(2.2u,4u); path rectangle; rectangle=z0--z1--z2--z3--cycle; picture X; X = image( drawoptions(withpen pencircle scaled 1.25 withcolor \MPcolor{orange}); draw (left--right) scaled 2; draw (down--up) scaled 2; drawoptions(); ); fill z0--z4--z3--cycle withcolor .5[red,green]; fill z1--z5--z2--cycle withcolor .5[red,green]; fill z0--z4--z5--z1--cycle withcolor 0.625white; draw z0--z4--z3--cycle; draw z1--z5--z2--cycle; draw rectangle; path a[]; a1 = subpath (0, 1) of rectangle shifted 10 down; a2 = subpath (3, 4) of rectangle shifted 10 left; a3 = subpath (2.26, 2.76) of rectangle shifted 13 up; drawdblarrow a1; label.bot("$30$", point 1/2 of a1); drawdblarrow a2; label.lft("$x+20$", point 1/2 of a2); drawdblarrow a3; label.top("$x$", point 1/2 of a3); draw X shifted z0; draw X shifted z1; draw X shifted z2; draw X shifted z3; draw X shifted z4; draw X shifted z5; label.ulft("B",z3); label.urt("C",z2); label.lrt("D",z1); label.llft("A",z0); label.top("E",z4); label.top("F",z5); \stopMPcode \stoptext
Also look at the LuaMetaFun manual chapter 8. In fact the whole manual is
worth a read. I'm sure you find much of use in it.
Best Wishes

Have a look into the Metafun manual, chapter 8.1 “shading”.

While the luametafun (“Metafun XL”) manual is also (meta)fun, I meant the general metafun(-s|-p) manual, the big one (>400 p. in the “print” version, >600 p. in the “screen” version). Recommended! Hraban Am 06.10.23 um 10:08 schrieb Keith McKay:

Hi,
Sorry for the late response. Thanks for the help. So I read the documents
and managed to get a gradient even if it's not exactly like the figure.

draw lmt_shade [
path = (z0--z4--z5--z1--cycle),
direction = "left",
alternative = "linear",
colors = {"black", "lightgray"},
] ;

Hi Fabrice, You could define you own shades of gray (I believe there are at least 50) by adjusting the rgb values as I've shown below. definecolor [ name = "verylightgray", r = 0.995, g = 0.995, b = 0.995 ] ; definecolor [ name = "lightergray", r = 0.55, g = 0.55, b = 0.55 ] ; draw lmt_shade [ path = (z0--z4--z5--z1--cycle), direction = "left", alternative = "linear", colors = {"lightergray", "verylightgray"}, ] xshifted 5cm; I added it to your code after the lines: draw z0--z4--z3--cycle; draw z1--z5--z2--cycle; draw rectangle; Hope this helps.
