large delimiters for equation
by Roger Mason 25 Nov '13

25 Nov '13

Hello, I'd like to have delimiters that match the height of the fraction in an expression like this: \startformula c\Delta T = t\big{(} \frac{c}{v_s} - \frac{c}{v_f} \big{)}. \stopformula I looked in the docs and tried a few likely solutions without luck. Please accept my apologies if this is documented eleswhere. Thanks, Roger

Now all issues with this font are solved (new issues within my actual project will surely follow, but no font-issues, I hope). I have to say once more, that I never had experienced before a such fast and competent software-support, that is at least as valuable as the software itself is! To your comments: Ok, yes, it is not a really normal font. It is specially designed for typesetting the holy quran (which is really no easy work). And there is so absolutely no problem that ALL numbers are mapped to ligatures -> there are no digits in the text of the holy quran :) (all numbers are written out at that time). Thanks again!

Every record should be ideally in the form: ID;page-number;Y-coord. \setposition{id} \message{id:\MPp{id};\MPy{id};\MPx{id}} should work (untested). Then you can parse the log file. Aditya

So, to clear all questions: for this min-example (which is at the moment my last unsolved problem with this font) I used this font: http://fonts.qurancomplex.gov.sa/download/UthmanicHafs1Ver09Font.zip And yes, Corel Draw uses this font, too. BUT: There might me some issue with this font relating this end-of-aya-symbol, independent from ConTeXt. See the attached JPG, which is the output of CorelDraw, if I input exactly the same arabic code, like in my example. You see in the picture a different behaviour between the one-digit and two-digit numbers aswell. But it is a different behaviour from ConText, the symbol is used, but the brackets are not replaced. Can you reproduce it now? Thanks! Huseyin

Placing a > combining Hamza over a Tatweel to “fake” it is wrong IMO. So in Amiri > you just type “بِءَايَٰتِ” and voilà, every thing is rendered correctly (the > same is true for the small Alef). Yes, that works. But the direct way works with Uhtmanic1HafsVer9: \definefont[arabicamiri][file:amiri-regular.ttf*arabic at 15pt] \definefont[arabicuth][file:UthmanicHafs1Ver09.ttf*arabic at 17pt] \starttext \setupalign[r2l] \arabicamiri بِـَٔايَـٰتِ \blank \arabicuth بِـَٔايَـٰتِ \stoptext To be honest, in Corel Draw UthmanicHafs is the perfect font for my purpose - at least in CorelDraw - e.g.: The ayat-numbers are printed as a unicode-symbol, not as numbers (perfect, because ConTeXt has problems with the direction with arabic numbers, they are mirrored in ConTeXt). But it is only perfect in CorelDraw, in ConTeXt some things are not recognized correctly, as I mentioned. E.g. this one: \definefont[arabicamiri][file:amiri-regular.ttf*arabic at 15pt] \definefont[arabicuth][file:UthmanicHafs1Ver09.ttf*arabic at 17pt] \starttext \setupalign[r2l] \arabicuth لِّلْمُتَّقِينَ ﴿٢﴾ \stoptext If I put the same arabic into CorelDraw, it prints a nice Unicode-Symbol for the number - see the JPG I have attached here, screenshot from CorelDraw, but ConTeXt ignores the brackets and prints just a verys small number. There are some problems like this. Are they easy to fix, or is this problem deeply involved? Huseyin

Hi Ondra, thanks for your help. > Apparently, replacing a number enclosed in ornate parentheses (U+FD3E > and U+FD3F) with a number in the "end of ayah" ornament is a specialty > of the UthmanicHafs font. If I input the digit (e.g. U+0662) and then > the special non-printable "end of ayah" character (U+06DD), ConTeXt > and Amiri successfully output the digit inside the ornament. Hmm, ok. But if it is a speciality of UthmanicHafs, why CorelDraw understands it natively? > Of course, since U+06DD is a non-printable character, it might be a > pain to work with in a text editor; you might want to define a custom > command for this purpose: > > \def\eoa#1{#1\char"06DD} Thanks, that works fine: \definefont[arabicamiri][file:amiri-regular.ttf*arabic at 15pt] \definefont[arabicuth][file:UthmanicHafs1Ver09.ttf*arabic at 17pt] \def\eoa#1{#1\char"06DD} \starttext \setupalign[r2l] \arabicuth لأَفَبِهَـٰذَا ٱلْحَدِيثِ أَنتُم مُّدْهِنُونَ ﴿٨١﴾\eoa \stoptext But now another question arises: How to input this command into my unicode of quran automatically? (I am using notepad++). Not the best way to do this manually for all 286 Ayas (and then search and replace for all ayas of all suras). And still: There must be some tricks in CorelDraw handling fonts, which would be great to have in ConText :) Thank you! Huseyin PS: Sorry for these annoyong thread-breaking all the time - I really do not know, what I make wrong here. I am using Thunderbird. If anybody knows how to use thunderbird for email lists correctly, I would be thankful.

The first aya, with a single one-digit number is not regonized correctly, but the second is (with a two-digit-number). Why? Huseyin
