i want to produce a gradient header
i tried this code but it does not produce any result:
\startext
\def\Mystyle#1{\startMPcode
picture tt ; tt := lmt_outline [
kind = "path",
text = "#1",
] ;
fill
for i within tt : pathpart i && endfor cycle
withshademethod "linear"
withshadedirection up
withshadecolors (red, blue) ;
\stopMPcode
}
\definehead[Myhead][section]
\setuphead[Myhead][
style=\Mystyle,
]
\startMyhead[title=sample] a sample text \stopMyhead
\stoptext
You can't use commands with parameters as argument for the style key.
To format single parts (number or title) of a section title you have to
apply a command to the "deep...command" key but even then you have to
make manual changes to the vertical alignment of the text.
%%%% begin example
\starttexdefinition spaces Mystyle #1
\setbox\scratchboxone\hbox{#1}%
\setbox\scratchboxtwo\hbox\bgroup
\startMPcode
picture tt ; tt := lmt_outline [
kind = "path",
text = "#1",
];
fill
for i within tt : pathpart i && endfor cycle
withshademethod "linear"
withshadedirection up
withshadecolors (red, blue) ;
\stopMPcode
\egroup
\boxyoffset\scratchboxtwo-\dp\scratchboxone
\box\scratchboxtwo
\stoptexdefinition
\starttext
\setuphead
[section]
[
deeptextcommand=\Mystyle,
% deepnumbercommand=\Mystyle,
]
\startsection[title=Lorem ipsum]
\samplefile{lorem}
\stopsection
\stoptext
%%%% end example
and the code below works but does not colorize numbers of this heads:
\starttext
\def\Mystyle#1{\startMPcode
picture tt ; tt := lmt_outline [
kind = "path",
text = "#1",
] ;
fill
for i within tt : pathpart i && endfor cycle
withshademethod "linear"
withshadedirection up
withshadecolors (red, blue) ;
\stopMPcode
}
\def\startMysection#1{\startsection[title=\Mystyle{#1}]}
\def\stopMysection{\stopsection}
\startMysection{hello}
what is best method?
\stopMysection
\stoptext
what is your suggestion?
To apply the format the the complete section title you have to create
your own style and apply it with the "command" key, to get the number
and title for the current section use the \structurenumber and
\structuretitle macros.
%%%% begin example
\starttexdefinition spaces protected Mystyle #1#2
\startMPcode
picture tt ; tt := lmt_outline [
kind = "path",
text = "\structurenumber\space\structuretitle",
];
fill
for i within tt : pathpart i && endfor cycle
withshademethod "linear"
withshadedirection up
withshadecolors (red, blue) ;
\stopMPcode
\stoptexdefinition
\starttext
\setuphead
[section]
[command=\Mystyle]
\startsection[title=Lorem ipsum]
\samplefile{lorem}
\stopsection
\stoptext
%%%% end example
