textbackground and margin
by Aditya Mahajan 19 May '06

19 May '06

Hi Hans, textbackground does not honour topoffset/bottomoffset at pagebreak. Is this by design? \definetextbackground [test] [ location=paragraph, rulethickness=1pt, leftoffset=1em, topoffset=5cm, bottomoffset=5cm] % For test purposes \starttext \starttextbackground[test] \dorecurse{15}{\input knuth \endgraf} \stoptextbackground \stoptext Is there some parameter to adjust the offset before and after a pagebreak. (I want them to be same as bottomoffset and topoffset.) Or should I take care of this in mpos:par:columnset with something like (pseudo code) if nofmultipars > 1 draw multipars[1] enlarge bottom by bottomoffset; for i = 2 upto nofmultipars: draw multipars[i] enlarge top by topoffset enlarge bottom by bottomoffset; endfor; endif; Or is there some easier way to just I influence boxfilloffset for do_draw_par in core-mp.tex?

Tex Errors But Good PDF Output
by Browder, Tom 19 May '06

19 May '06

I'm using definitions and abbreviations in section titles and get errors from TeX during processing (using texexec). If I ignore the errors and hit return repeatedly, eventually the process ends and I get an apparently good PDF file. I've included the log file--notice the complaints about undefined control sequences. I'm using a master tex file and \input the various chapters (I've turned off all but a couple of inputs for debugging). Is there anything apparent I'm doing wrong? Thanks so much. -Tom

--batch --interaction=batch does not always process file in batch mode, while internally running mp. \starttext \startMPpage draw path ; \stopMPpage \stoptext texmfstart texexec.rb --batch --interaction=batchmode --pdf test should not stop at the error. However it does. Running ConTeXt ver: 2006.05.08 23:37. Aditya -- Aditya Mahajan, EECS Systems, University of Michigan http://www.eecs.umich.edu/~adityam || Ph: 7342624008

Framed in nested enumeration
by Aditya Mahajan 19 May '06

19 May '06

Hi, Inside a nested enumeration \frame[align=leftflush] does not work correctly. For example \defineenumeration [problem] [text=Problem, location=hanging, headstyle=\sc, % headcolor=brown, % before={\resetnumber[formula]\page[desirable]}, after=\blank, ] \defineenumeration [solution] [ text=Solution, number=no, % headcolor=darkblue, headstyle=bold, location=serried, width=broad, before=\blank, after=\blank, ] \starttext \startproblem \input knuth %A multi paragraph problem \startsolution A multi paragraph solution \leftaligned{In leftaligned works fine} \framed[frame=on,align=leftflushed,width=broad] { Inside framed does not} \startformula \stopsolution \stopproblem \stoptext Is there an option other than align=leftflushed for this kind of thing. Thanks, Aditya -- Aditya Mahajan, EECS Systems, University of Michigan http://www.eecs.umich.edu/~adityam || Ph: 7342624008

textbackground and midaligned
by Aditya Mahajan 19 May '06

19 May '06

I encountered a very strange problem. The very presence of \definetextbackground changed the meaning of \midaligned (and \rightaligned). Attached are the minimal example that illustrate the problem. The first file, nobackground.tex has no background and works as expected. The second file background.tex has a textbackground and \midaligned is no longer middle aligned. Any insight into this strange behaviour? Aditya -- Aditya Mahajan, EECS Systems, University of Michigan http://www.eecs.umich.edu/~adityam || Ph: 7342624008

Weird texexec hang
by nico 19 May '06

19 May '06

Hello, I took me quite some time to extract the following sequence from a 300p book, that makes the compilation hang. It looks like if it's in an infinite loop, but I don't know what happens. It seems related to the interaction of float, verbatim, and background stuff. I thought it was a local resource problem (few memory on my machine) but trying the code in live context never gave something either (i hope it is not still running!). What's wrong in my definitions/setups to have such a behaviour? \setuplayout[middle] \setupcolors[state=start] \setupinteraction[state=start] \definefloat[dbsidebar] \setupfloat [dbsidebar] [criterium=0.7\textwidth, leftmargindistance=-\outercombitotal, rightmargindistance=-\outercombitotal, default={outer,middle}] \setupcaption[dbsidebar][location=bottom,number=no] \defineframedtext [framesidebar] [width=.9\textwidth,bodyfont=small, corner=round,background=screen,backgroundscreen=.95] \setupbackground [background=screen, frame=on, strut=yes, topoffset=2mm, width=broad, before=\blank, after={\blank[small]}, align=right] % Verbatim environment for programlisting \definetyping[code] \setuptyping[code] [bodyfont=small, before={\startbackground}, after={\stopbackground}] \starttext \input tufte \input tufte \placedbsidebar{joke} {\startframesidebar \startcode some code \stopcode \stopframesidebar} \input tufte \input tufte \placedbsidebar{joke} {\startframesidebar \startcode some code \stopcode \stopframesidebar} \stoptext Regards, BG

definitions local to a component
by Sanjoy Mahajan 19 May '06

19 May '06

What's the safe way to make \def's local to a component? I could wrap each component in a \begingroup..\endgroup but that might do bad things to the output routine. -Sanjoy `Never underestimate the evil of which men of power are capable.' --Bertrand Russell, _War Crimes in Vietnam_, chapter 1.

Wrong image size evaluation
by nico 18 May '06

18 May '06

Hello, I have some troubles with a PNG image, that is not correctly rendered by context (too small). The difference I've found with another correctly displayed image is that the file does not contain any resolution unit (but a pixels/inch default seems reasonable). Is there a workaround or specific setup to make this work (without explicit width setting)? Here is the test file I use. If you wish I can send the images, or find the troublesome PNG image at: http://svnbook.red-bean.com/trac/browser/trunk/src/en/book/images/ch01dia1.… Thanks for your help. \starttext \startyping identify -verbose images/ch02dia1.png images/ch02dia1.png PNG 146x168 146x168+0+0 PseudoClass 135c 2kb 0.008u 0:01 Image: images/ch02dia1.png Format: PNG (Portable Network Graphics) Geometry: 146x168 Resolution: 28.34x28.34 Units: PixelsPerCentimeter \stoptyping \externalfigure[images/ch02dia1.png] \startyping identify -verbose images/ch01dia1.png images/ch01dia1.png PNG 511x585 511x585+0+0 DirectClass 54kb 0.094u 0:01 Image: images/ch01dia1.png Format: PNG (Portable Network Graphics) Geometry: 511x585 Resolution: 72x72 Units: Undefined \stoptyping \externalfigure[images/ch01dia1.png] \stoptext Regards, BG

Dense encoding, part II ???
by Mojca Miklavec 18 May '06

18 May '06

Hello, on the [tex-fonts] mailing list there was a recent discussion of people putting effort into enabling proper encoding to support typesetting of Lithuanian (in LaTeX). Before they start creating and using yet another encoding (incompatible with others and not shipped with any standard TeX distribution): is there any chance to finish the companion encoding in some reasonable time? Even if they keep using LaTeX, I think that the same mechanism can be used in LaTeX as the one which combined EC (T1) with TS1. There is probably not that much left to be done. The letter part of the encoding is finished (and the Polish fonts already ship with those metric files) and quite some ideas for the companion font are already there. The major part left is to create ConTeXt support for combining two encodings, but from the past experiance with Hans that is probably a matter of not even a couple of hours. Or should we wait for Oriental TeX first? Mojca
