The ConTeXt mailing list is probably more suitable for this discussion, so I'm redirecting your question there (if anyone responds to it). On 5/2/07, Stephan Hennig wrote:
Hi,
my attempt to shade a piece of text with MetaFun fails (see below). Is this a restriction of MetFun/MetaPost or of the PDF format?
While there is an explicit example for transparent text in metafun-p.pdf on p. 185 I didn't find one for shaded text. Is shading text possible?
Best regards, Stephan Hennig
input metafun beginfig(1); sh_sqr := define_linear_shade(origin, (100bp,0), white, blue); sh_txt := define_linear_shade(origin, (100bp,0), white, red); fill unitsquare scaled 100bp withshade sh_sqr; label("Not shaded!", (50,50)) withshade sh_txt; endfig; end
Compile with
mpost shad mptopdf shad

It should be possible to do it inside PDF, but it's not implemented (yet?).
Thanks. Would be a nice feature for, e.g., invitation cards.
PDF uses 8 different kinds of text: filled, stroked (already implemented with \starteffect[outline]...\stopeffect), ... and some others. See Chapter 5.2 of PDF reference manual. You probably need Text rendering type 4. Extending support for it would be a nice excercise in metafun programming, but I'm too slow to figure it out in a reasonable time. I *really* need to finish extending smooth shading patterns to a more generic model, and I will keep your problem in mind in case it remains unsolved, but don't count on me if you need it now. There are some people on the ConTeXt mailing list (apart from Hans of course) who might be able to help. Mojca
