Re: \MPpos, pxy, initialize_box(), oh my! (Hongwen Qiu) hi hongwen, thanks for taking an interest. my initial post had a mistake: i meant to refer to the /Metafun/ manual, not the Metapost manual. that probably didn't help. i guess what i should have said is, i know that pxy can give me the bounding /box/ (the rectangle with the maximum horizontal and vertical extents of its contents, be they set in horizontal or vertical mode), but can it give me the subset of that, the bounding /path/, if you will, when the contents are text which flows over several lines. the bounding /path/ may not be rectangular, although it will be something like the union of the bounding boxes of the text's individual lines. i think if you look at the correct reference, the difference of the effects is clear. i think the challenge is that you don't know where the line breaks will occur until you typeset it. --adam [-- Attachment #2: adam_fuller.vcf --] [-- Type: text/x-vcard, Size: 446 bytes --] begin:vcard fn:Adam Fuller n:Fuller;Adam org:University of Canterbury;Mechanical Engineering adr:Private Bag 4800;;Intersection of Creyke Rd and Engineering Rd;Christchurch;Canterbury;8041;New Zealand email;internet:adam.fuller@pg.canterbury.ac.nz title:Ph.D. candidate tel;work:(+64) 3 364 2987 ext. 8390 tel;fax:(+64) 3 364 2078 tel;home:(+64) 3 366 3455 tel;cell:(+64) 21 0254 8677 url:http://www.mech.canterbury.ac.nz/ version:2.1 end:vcard [-- Attachment #3: Type: text/plain, Size: 486 bytes --] ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 7+ messages in thread

In the latter case it can be calculated directly after the paragraph is typeset, but in the former case a second pass is needed. \tpos {A-5} Given the above code, I think you can get some information about the horizontal and vertical pos of texts from \fpos and \tpos. And the mpos:par is defined in anch-pgr.mkii and anch-pgr.mkiv. But I haven't dig into the code which implement mpos:par. Hope you can find useful information there.

I still think that the extra space before "y" and "z" would be appreciated. But nevertheless, different settings for different needs sounds like a good idea.

It should be bigger than the space after the x. I could work around it by typing $a,\,x,\dots,\,b$ but this is somewhat inconvenient and even a bit too much spacing... On the other hand, the spacing before \dots is just right, but the spacing after \dots is too small: the spaces between commas and periods ",...," should all be the same. Is this a bug? Can this be changed by a global option or something? Thanks for any help in advance.

(Are you using MKIV or MKII)? I had a similar issue with MKIV. autopunctuation=no fixed it for me. ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 7+ messages in thread
