clipping bug [or the return of the long cat]

clipping bug [or the return of the long cat]

[Peter Rolf]

hi,

this time fully 'context live' approved, only with natural ingredients
and even more tasty. yummy yum :D



% engine=luatex
\starttext

\definelayer[stack]

\setlayer[stack][x=0pt,y=0pt]{%
\clip[hoffset=0pt,voffset=0pt,width=20cm,height=1cm]%
{Clipping some layer text}}

%\flushlayer[stack]

\setbox\scratchbox\hbox{The cat was too long to fit in this small sentence.}
\framed[offset=overlay]{\clip[hoffset=0pt,voffset=0pt,width=110pt,height=15pt]{\box\scratchbox}}

\stoptext



the second clip uses the width value of the prior clip (20cm).
but if the layer is flushed, the second clip works nearly as expected 
(only frame is missing). interesting.
there also seems to be some mess (or only a side effect?) with the
setting of

\setupsystem[\c!n=2,\c!m=2]

sometimes the number one is used, sometimes the number two.
must break, it's supper time.


regards, peter

there seem to be an ugly sideeffect in combination with \startTEXpage .. 
\stopTEXpage. I use this to encapsulate my test graphics. The resulting 
page is only 1.1mm width (tested with several different sized gfx; width 
is always this value, height is normal).

all tested with the beta from 07.06.2008 and luatex trunk (08.06.2008). 
todays beta has additional problems with text color (always black) and 
also some unicolored backgrounds appear black only. so i went back to 
the prior beta version and changed only the clip part.

regards, peter

hm ... example ...

(keep in mind that mkiv's color handling is like fonts, i.e. no coloring 
of unboxed stuff as in \color[red]{\box\whatever})

:)

only a very big one (with non public code). currently no time, but i 
will try to create some small examples later.

yes. it's also possible, that i have to adapt my code again.

all i can say at the moment is, that it works with the beta from 
07.06.2008 and fails with the current. we will see (shouldn't be a hard 
problem).

hmmm, another try (but same result)


% engine=luatex

\startuniqueMPgraphic {foo}
   fill OverlayBox;
\stopuniqueMPgraphic
