clipping bug [or the return of the long cat]
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

:) only a very big one (with non public code). currently no time, but i will try to create some small examples later.
(keep in mind that mkiv's color handling is like fonts, i.e. no coloring of unboxed stuff as in \color[red]{\box\whatever})
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). peter
