[NTG-context] Re: Fwd: Re: how to apply gradient color to a piece of text?

10 Apr 2024

      seams this code means to put a hidden text with same size behind metapost
shape.
but it does not work properly for me (current version: 2024.04.01 08:59)
and produce empty page but with searchable hidden text.
also when i edit the code and replace metapost part like this:

\startMPcode
     draw lmt_outline [
         kind = "outline",
         text = "\getbuffer[MyText]",
      ]
         withcolor red
      ;
\stopMPcode

it produces a selectable hidden text on top of body and red text that drawn
by metapost below of that.

How can this problem be solved?

i attached the codes and pdf results.

thank you Harban and Keith McKay.
\startMPpage
           picture tt ; tt := lmt_outline [
               kind = "path",
               text = "\definedfont[name:texgyrepagellabold*default]foo
    f o o",
           ] ;
fill
              for i within tt : pathpart i && endfor cycle
              withshademethod "linear"
              withshadedirection down
              withshadecolors (red, blue) ;
    \stopMPpage
I'll add this:
\startMPpage
          draw lmt_outline [
              kind = "outline",
              text = "\definedfont[name:texgyrepagellabold*default]foo f
    o o",
          ]
              withshademethod "linear"
              withshadedirection down
              withshadecolors (red, blue)
          ;
    \stopMPpage
so a single path option (no picture)

Thank you so much for the sample examples
it would be great to also make text select able in output pdf
the third example currently does not work. did you mean you will add
this feature for next updates?
we're talking outlines so that is paths which implies no search but you
can do this (Keith and/or Hraban will explain and/or wikify it)
\starttext
\startbuffer[MyText]
     \definedfont[name:texgyrepagellabold*default]foo f o o%
\stopbuffer
\startbuffer[MyText]
     \framed[align=normal,frame=off]{\input{tufte}}%
\stopbuffer
\setbox\scratchbox\hbox\bgroup
     \startMPcode
          draw lmt_outline [
              kind = "outline",
              text = "\getbuffer[MyText]",
          ]
              withshademethod "linear"
              withshadedirection down
              withshadecolors (red, blue)
          ;
     \stopMPcode
\egroup
\startoverlay
{\scale[height=\htdp\scratchbox,width=\wd\scratchbox]{\effect[hidden]{\getbuffer[MyText]}}}
     {\box\scratchbox}
\stopoverlay
\stoptext
