Dear Hans,
I read the “luametafun.pdf” and run the codes one by one.
It is a really nice to have those figures easily.
During the reading, I found that there is a difference between the
figure in the manual and the output of my run.
I run the following code at page 24-25 in “luametafun.pdf”.
\startMPcode{doublefun} draw lmt_contour [
xmin = 0, xmax = 4*pi, xstep = .05,
ymin = -6, ymax = 6, ystep = .05,
levels =7,
height = 5cm,
preamble = "local sin, cos = math.sin, math.cos",
function = "cos(x) + cos(y)"
background = "bitmap",
foreground = "edge",
linewidth = 1/2,
cache = true,
];
\stopMPcode
In the output, the background of text is gray while the background of
text in the manual is white.
Here are versions of LuaMetaTeX and ConTeXt which I use.
%%%%%%%
This is LuaMetaTeX, Version 2.03.4
