Thank you! Yes, it would be great to learn more about MetaFun - if you 
can point me to the test suite, then I can document a few good tutorial 
level examples in the Wiki (beginner & intermediate). MetaFun's turbo 
charged capabilities are awesome!


the test suite is a zip on the website alongside the others (not only 
metafun)


best is to to look at the luametafun manual in the distribution (which 
is anyway where the tests come from)


there is also the metafun manual (that i occasionally update / extend) 
but the newest things are in the luametafun manual

Hans,

Thank you! Yes, it would be great to learn more about MetaFun - if you can
point me to the test suite, then I can document a few good tutorial level
examples in the Wiki (beginner & intermediate). MetaFun's turbo charged
capabilities are awesome!

One idea I am thinking (maybe for a student level project) would be MetaFun
library for Figma  (popular design tool).

Hans,

Thank you for the snippets. These are super helpful (I am assuming commands
like `withpatternscale` are MetaFun extensions and Wow!).

I have added them to a new Wiki Page -
https://wiki.contextgarden.net/Fill_Patterns and linked it the main MetaFun
wiki page - https://wiki.contextgarden.net/MetaFun_-_MetaPost_in_ConTeXt

Thanks again!

best regards,
Ramkumar

[NTG-context] Best way to apply a fill-pattern to a closed shape?

2021-08-28 Thread Ramkumar KB via ntg-context 
Hello List,

I have a use case to apply a particular pattern to a closed shape. I am
using Metapost for the figures.

After some research this package seems to quite good, in terms of having
all the patterns normally used -  https://ctan.org/pkg/minim-hatching

But I could not figure out how to use this with ConTeXt. Or maybe there is
already a better way to do this in ConTeXt and am missing that trick.

Any tips would be really helpful.

Thank you.

Best regards,
Ramkumar
