Hi,
I make a hole in a MetaPost graphic and add a graphic as background but
in MkIV I get no hole but the lines I try to remove are still visible.
All files with the two results from MkII (what I want) and MkIV are in
the attachment.
\starttext
\startMPcode
picture temp ;
path mask ;
draw (0,1cm)--(2cm,1cm) ;
draw (1cm,0)--(1cm,2cm) ;
temp := currentpicture ;
currentpicture := nullpicture ;
mask := unitsquare scaled 2cm -- reverse fullsquare scaled 1cm shifted
(1cm,1cm) -- cycle ;
clip temp to mask ;
currentpicture := temp ;
draw fullsquare scaled 5mm shifted (1cm,1cm) ;
temp := currentpicture ;
currentpicture := nullpicture ;
externalfigure "holz280.jpg" scaled 2cm ;
addto currentpicture also temp ;
\stopMPcode
\stoptext
Wolfgang

i have no clue (nor time to look into it in detail) but this seems to
work ok:
% engine=luatex interface=en
\starttext
\startMPpage
externalfigure "cow.pdf" scaled 2cm ;
clip currentpicture to boundingbox currentpicture -- reverse
unitsquare scaled 1cm shifted (.5cm,.5cm) -- cycle ;
\stopMPpage
\stoptext
