Re: [NTG-context] Metapost and TikZ color code equivalent

15 Feb 2020


      Hi Henri,
Why does the blue path not rotate 90 with the draw command but rotate with
the fill command ?

\startMPcode

  def match (expr alpha, pos) =
    fill unitsquare xscaled 4cm  yscaled 0.2cm rotated alpha shifted pos
    withcolor yellow ;
    fill origin -- (4cm,0) -- (4.1cm,-0.05cm) --  (0.1cm,-0.05cm) --
    cycle rotated alpha withcolor(.6yellow + black);
    draw origin -- (0,0.2cm) -- (4cm,0.2cm) -- (4cm,0) -- (4.1cm,-0.05cm)
    -- (0.1cm,-0.05cm) -- cycle rotated alpha withcolor blue;
     draw origin -- (0,0.2cm) -- (4cm,0.2cm) -- (4cm,0) -- (4.1cm,-0.05cm)
    -- (0.1cm,-0.05cm) -- cycle rotated alpha withcolor blue;
    draw fullcircle xscaled 0.50cm yscaled 0.44cm shifted (4.125cm,0.1cm)
    rotated alpha;
    draw fullcircle xscaled 0.50cm yscaled 0.44cm shifted (4.125cm,0.1cm)
    rotated alpha
    withshademethod "circular 1"
    withshadevector (0,1)
    withshadecolors (red,white);
    enddef;
  match(0,(0,0));
  match(90,(4.2cm,0));
  match(90,(0,0));
  match(0,(0,4.2cm));

\stopMPcode

Hi,
Hi,
I have corrected for the dimensions of the ellipse but I cannot achieve
the same effect for the red color.
Thank you.

How to have the color defined by {yellow!60!black} with Metapost ?
color MyColor ; MyColor := .6[yellow,black] ;
See metafun manual, section 1.13.
Thank you.
