Hi John, John Culleton schrieb:
A project specifies that for the cover of a brochure there be a photograph as the background (doable in Context), and semi-transparent rectangles across the page highlighting the various strings of text. The rectangles darken but do not completely block out the underlying illustration. It is a layer cake, a photo, with semi-transparent rectangles laid across it, and type within the rectangles.
This is a job more easily done in Gimp etc. but my question is, can it be done in Context at all? How do I create the semi-transparent elements?
something like \startuniqueMPgraphic{transp:dim} fill OverlayBox withcolor transparent(1,.25,white); % mode,transp.,color \stopuniqueMPgraphic \defineoverlay[transp:dim] [\uniqueMPgraphic{transp:dim}] \framed[background=transp:dim]{your text} There are some problems with transparency in MP at the moment, so the fill color is fixed and not a parameter of the MP graphic. Anyhow, this should do the job. Peter
