Hi everyone! I have a question regarding transparency groups in MetaFun. As a toy example, I want to draw a grid of lines where the whole grid should have an opacity of 25%. If I draw intersecting lines individually with `withtransparency(1, .25)` the overlapping parts will have a total opacity

[NTG-context] MetaFun manual's "texvar" is not working for me

Hello list, I’m trying to reproduce the positional graphics examples in the MetaFun manual on pp. 151-153. There are two examples of code for the mpos:box. The first example uses \MPvar to retrieve variables set using \setupMPvariables. This works fine. The second example uses texvar to

Hi Wolfgang, Thank you for your reply. I did as you suggested but it still never worked. However it did make me delve further into the Metafun, LuaMetaFun and the Colouring ConTeXt manuals where I found examples of the *resolvedcolor* helper which I used as follows: definecolor [name

Hi Fabrice Thank you for your reply. It works the way I wanted. Wolfgang also replied and this has lead me to an alternative method. See my reply to him in this mailing list. Best Wishes Keith On 28/04/2022 13:45, Fabrice L wrote: Sorry, I was a little too enthusiastic, here here is the co

Hi, In the MWE below I define an rgb colour, myColor1, using random numbers for the r, g and b components. I then use it to fill a unitsquare the size of the page, which works as expected. In the loop that follows I then use the defined colour, myColor1, along with white and the variable r to

[NTG-context] $\sin \theta$ behave differently in metafun

Dear all, I use $\sin \theta$ and $\cos \theta$ behave differently in text and in metafun. It works well sometime before but it doesn’t in metafun now. What is wrong in my example? Thank you for reading. Best regards, Dalyoung Here is a MWE. \startbuffer[pointCircle] numeric u; u:=1cm; pair
