background offsets

background offsets

[Jens-Uwe Morawski]

Hi,

for a screen-document i draw an overlay under the text-area.
The overlay is a simple MP-figure:

fill unitsquare yxscaled(\overlaywidth+6pt,\overlayheight+6pt) 
	withcolor transparent (1,0.7,white) ;

This overlay is centered under the text-area giving a 3pt offset
to every side.

I would prefer to specify the offset in the \setupbackgrounds
command:
\setupbackgrounds[text][text][offset=3pt,background=<overlay-name>]

and use in the MP-figure only:
fill unitsquare yxscaled(\overlaywidth,\overlayheight) 
	withcolor transparent (1,0.7,white) ;

but this only works for \framed, not for \setupbackgrounds. Why?

Thanks.

Best,
  Jens

fill unitsquare xyscaled(OverlayWidth,OverlayHeight) enlarged 6pt ;

so it's under the text, then why is it transparent?

backgroundoffset=3pt

ahh, so many MetaFun commands i don't know about :)

BTW, i've tried hyperpath, hyperlink but it corrupts my PDF file.
Have you used it successfully?

because it looks nice -) Using a transparent white text background
on top of a colored page background gives a not totally white
background for the text. Thus there is enough contrast for the
text but it looks not that flashy.

in the MetaFun manual is written that offset applies to both frame
 _and_ background. Thus i thought using offset would be enough.

Thanks.
