[NTG-context] memoir-style chapter heading
Am completely new to using Metafun, which I presume I would need to use to achieve a Hansen Memoir-style Chapter heading (chapter title overlayed on a large lightgray number). Of course, I am assuming I would need to use Metafun to create this... So my first question is to ask if I could achieve the same effect without Metafun? I have read through the Metafun manual, and I think I can understand how to overlay text on a graphic (MP), but it would be currently beyond me to draw numbers of the kind we find in, say, the Memoir examples. Has anyone created such an example? I was keenly looking for one in the manual and elsewhere, in terms of ConTeXt/Metafun commands, but could not find one. But I'd be quite prepared to 'have a go' at this, if I had some pointers of just where to start! I assume I would have to \defineoverlay[number] and then add text on top \framed (but without the frame borders). Am I at least correct about this?

Jairo
Try
draw unitsquare scaled 1cm shifted (xcm, ycm);
Page 11 of the manual metafun-p.pdf is your friend here. My recent
conversation with Taco on this list will be usefull as well.

Many thanks for your reply, Taco.
This was extremely handy and helpful (it is also the first time I
understand what \xmlfilter is used for).
My final solution required nesting filters, which worked perfectly fine
(included below).
Many thanks for your help,

Re: [NTG-context] Missing graphic in MPpage when viewing in Apple MAC Preview or GIMP 2.10 but not Adobe
Thanks Taco!
I have been playing about with an example from this site
https://tex.loria.fr/prod-graph/zoonekynd/metapost/metapost.html
which was originally for a square and I obviously didn't get my angles
right. Thanks for spotting it. I'm beginning to appreciate where the Fun
in MetaFun comes from.

Hi Keith,
It took me a while before I saw it, but I think you wanted to type in
z0 = (60,60);
z1 = z0 rotated 120;
z2 = z0 rotated 240;
instead of
z0 = (60,60);
z1 = z0 rotated 120;
z2 = z1 rotated 240;
because the latter puts z2 at z0, resulting in a path that is a straight line. The
fact that AR displays anything at all is probably some form of correction like
"fill of empty path == single pixel line”.

Dear List
I have come across a problem which I don't think is due to ConTeXt but I'm
hopping the great and the good of this list may be able to explain what is
going on.
The code below produces an MPpage with a shaded background and two graphics
along with a line of outlined text. When I view in Adobe (or the output from
TeXworks) I see everything as it should be. However, I wanted to convert the
MPpage to a jpeg file and when I opened the pdf in either Apple MAC Preview or
Gimp 2.10 the two graphics are missing, and I have no idea why.
Could someone explain a way round this? Here is the code.
Thanks

There is no way to change the color of the title page from your module itself, the only way is to change the value module (s-module-basic.mkiv) which is used to create the formatted source. The same has to be done to disable the frame where you have to comment the \showframe line in the module mentioned above.
