fitting a picture to the available space
by Thomas A. Schmitz 12 Sep '08

12 Sep '08

Hi guys, I'm pulling my hair out. I'm trying to set up an automatism to fit pictures to the available space on a slide. I need to consider three parameters: 1. If the user supplies a value for width= or height= , use this value (captured in a macro); 2. respect the maxwidth and maxheight which must not exceed the frame; 3. if the picture is smaller than the available space, blow it up so that it reaches the maxwidth or maxheight (but doesn't exceed either). factor=max or =fit does not work because it allows pictures to exceed one of the maximum values. About a year ago Giuseppe Bilotta wrote a message which I append; it describes my problem. Is there a generic solution for this problem? If there is, I'll gladly take it; if there isn't, I thought I had a solution but may need help with expanding and conditionals, then I'll be back with more questions. Anyway, good night all, and thanks.

Hi, I am using ConTeXt ver: 2008.09.10 14:01 MKIV fmt: 2008.9.11 and the following file \starttext \startMPcode label.bot(\sometxt{$\mathop{}$}, origin) ; \stopMPcode \stoptext gives !

Missing number, treated as zero. <to be read again> ## It runs correctly with MKII. Any ideas? Aditya

frameoffset in textbackground
by Wolfgang Werners-Lucchini 12 Sep '08

Hallo, I asked this question a week ago, but got no answer. Does anybody know what is 'frameoffset' for? I can not see any difference with and without this parameter. ---------------------------------- \setupcolors[state=start] \definetextbackground[strong] [backgroundcolor=lightgray, location=paragraph, frame=on, frameoffset=5mm] \starttext bla \starttextbackground[strong] zack \stoptextbackground blub \stoptext ------------------------------------ Wolfgang

Request for "digested" readers: please change subject
by Mojca Miklavec 12 Sep '08

12 Sep '08

Hello, ConTeXt mailing list is really a huge one and an overkill to follow it as a whole. But to all those of you who read mail in digested mode: feel free to hit reply and answer there, but then please: a) delete all the other non-relevant 24 messages in the digest b) If original subject was "ConTeXt rules!", please change the subject from "ntg-context Digest, Vol X, Issue Y" into "Re: ConTeXt rules!" or "Re: [NTG-context] ConTeXt rules!" It will still mess up the threading a bit (this happens a lot anyway), but simplify matters to all other readers of the mailing list. I think that gmane offers some possibility to answer via their interface as well, but I have never tried it. Thanks a lot, Mojca

One very silly question
by Yue Wang 12 Sep '08

12 Sep '08

Hi, I read the manual, and it said: rm, ss,tt,hw,cg are styles, bf,it,bi,sl,bs, sc, os, tf are alternatives. one can use one alternative in one style like \rm\bf. However, I think we should add more alternatives like boldsmallcaps or bold old style number? in opentype, smcp, onum are just features, and every alternatives (like bold, bold italic) have them. btw, I think there should be a (fontconfig like) mechanism for setting up opentype fonts easier?

installation of ConTeXt
by Goebel, Juergen 12 Sep '08

12 Sep '08

Hi, Do I really have to install ruby? I downloaded it, but can't find anything like install, setup or something like this. Even the readme is not very helpful at all. And another question: for using Ruby - and therefore ConTeXt - do I need cygwin? Regards, Juergen

Re: [NTG-context] rows and columns in TABLE (fwd)
by Peter Münster 11 Sep '08

11 Sep '08

Hello, I would like to adjust the height of each row. But I manage to get the desired result only with a seventh dummy column. Consider this example with and without the mode "seven": %\enablemode[seven] \starttext \setupTABLE[r][2,3,4,5,6,7][height=6ex] \bTABLE[width=0.125\textwidth] \bTR \bTH 1. col\eTH \bTH 2. col\eTH \bTH 3. col\eTH \bTH 4. col\eTH \bTH 5. col\eTH \bTH 6. col\eTH \doifmode{seven}{\bTH 7. col\eTH} \eTR \bTR \bTD[nr=6]6 rows in 1. col\eTD \bTD[nr=2]2 rows in 2. col\eTD \bTD[nr=6]6 rows in 3. col\eTD \bTD[nr=2]2 rows in 4. col\eTD \bTD 1 row in 5. col\eTD \bTD[nr=2]2 rows in 6. col\eTD \doifmode{seven}{\bTD\eTD} \eTR \bTR \bTD[nr=2] 2 rows in 5. col\eTD \doifmode{seven}{\bTD\eTD} \eTR \bTR \bTD[nr=2]2 rows in 2. col\eTD \bTD[nr=2]2 rows in 4. col\eTD \bTD[nr=4]4 rows in 6. col\eTD \doifmode{seven}{\bTD\eTD} \eTR \bTR \bTD[nr=2] 2 rows in 5. col\eTD \doifmode{seven}{\bTD\eTD} \eTR \bTR \bTD[nr=2]2 rows in 2. col\eTD \bTD[nr=2]2 rows in 4. col\eTD \doifmode{seven}{\bTD\eTD} \eTR \bTR \bTD 1 row in 5. col\eTD \doifmode{seven}{\bTD\eTD} \eTR \eTABLE \stoptext Any hints, you to adjust the heights without the dummy column? TIA for any help! Cheers, Peter -- http://pmrb.free.fr/contact/

A ConTeXt bug tracker to keep track of reported bugs?
by Khaled Hosny 11 Sep '08

11 Sep '08

I've reported several bugs (mostly Arabic related) and I'm afraid it might get lost as time goes, I wonder if there is a bug tracker for ConTeXt where we can track reported bugs? I searched the wiki and I didn't find any thing. -- Khaled Hosny Arabic localizer and member of Arabeyes.org team
