Creating a semi-transparent backdrop with metapost is quite simple,
but I am not sure whether that works with cmyk, you'll have to try
yourself. Code goes something like this:
For the records: This is, how I'll use it:
\startuniqueMPgraphic{texthole}
for dx = 0 upto 40:
dy := dx;
wa := 10 + dx;
wb := \overlaywidth - dx - 10;
ha := dy + 10;
hb := \overlayheight - dy - 10;
fill (wa,ha)--(wb,ha)--(wb,hb)--(wa,hb)--cycle
withcolor transparent("normal", .04, black);
endfor;
\stopuniqueMPgraphic
\defineoverlay[shaded][\useMPgraphic{texthole}]
\starttext
\rotate[rotation=12]{%
\framed[height=50mm, width=50mm, frame=off, background=shaded,
backgroundoffset=5mm, align=middle]%
{\offset[x=1mm,y=-2mm]{\externalfigure[koe][width=50mm]}}%
}
\stoptext
I'm glad I found \offset, because framed's offset parameter can't
distinguish x and y offset.
Positive offset moves right and down, negative offset moves just up -
I guess that's a buglet.
