Not for me either. I used it somewhere so I'll need to look back in my files.
\startMPpage picture tt ; tt := lmt_outline [ kind = "fillup", text = "\definedfont[name:texgyrepagellabold*default]foo f o o", ] xsized 12cm ; path bb ; bb := boundingbox tt ; path pp ; pp := bb enlarged 2cm ; fill pp withshademethod "linear" withshadedirection down withshadecolors (red, blue) ; draw tt withcolor green ; \stopMPpage no need to loop over tt ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

draw tt withcolor green ; \stopMPpage
no need to loop over tt
But the intention was to get a gradient _within_ the text. Might there be a problem with the latest changes to gradients? Hraban

I've found my original file and the image is as Hraban says below. The code is the original in the post I quoted and gives a green background with shaded colours in the text. Best Wishes Keith On 07/04/2024 18:42, Henning Hraban Ramm wrote:

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

\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)
Hans
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?

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.

as mentioned kind = "outline" will be in the next upload so with the current one you need to use the also posted here for ... endfor variant
also when i edit the code and replace metapost part like this:
\startMPcode draw lmt_outline [ kind = "outline", text = "\getbuffer[MyText]", ] withcolor red ; \stopMPcode
