* setups within typescripts: can it be done? @ 2013-03-11 16:51 Idris Samawi Hamid ادريس سماوي حامد 2013-03-13 1:01 ` Hans Hagen 0 siblings, 1 reply; 4+ messages in thread From: Idris Samawi Hamid ادريس سماوي حامد @ 2013-03-11 16:51 UTC (permalink / raw) To: ntg-context Dear gang, Here is the situation: For an upcoming book project I may use a set of proprietary fonts whose license that does not allow modification even for personal, private use. Some characters I need are absent, but the components I need are there (macrons, dots, etc). So I can conceivably use \defineactivecharacter to map each needed unicode char to a \def made of glyph components in the font. Now in a typescript we have different fonts: Each individual font needs its own setup in terms of \defineactivecharacter. So the final typeface will be able to associate each individual font with its associated setup. So here's my idea: ============== \startsetups font1 \defineactivecharacter b blah1 \stopsetups \startsetups font2 \defineactivecharacter b blah2 \stopsetups \starttypescript [serif] [name] \definefontsynonym [MyFont1][name:SuperFontRgular][features=myfeatures,fallbacks=myfallback,setups=font1] \definefontsynonym [MyFont2][name:SuperFontItalic][features=myfeatures,fallbacks=myfallback,setups=font2] \stoptypescript =============== Is this doable? If not is there another way? If doable, is there a better way? If this is totally undoable, then here is another approach: Is there a way in mkiv to make a definition that can translate the following: ========== If font1 is active use def1 If font2 is active use def2 : Else \relax ========== If not, are there any other ideas? Thanks in advance for any hints and guidance.

Not all fonts come with all combined glyphs. Although we have an auto|-|compose feature in \CONTEXT\ it sometimes helps to be specific with respect to some combinations. This is where the \type {compositions} goodie kicks in: \starttyping local compose = { [0x1E02] = { anchored = "top", }, [0x1E04] = { anchored = "bottom", }, [0x0042] = { -- B anchors = { top = { x = 300, y = 700, }, bottom = { x = 300, y = -30, }, }, }, [0x0307] = { anchors = { top = { x = -250, y = 550, }, }, }, [0x0323] = { anchors = { bottom = { x = -250, y = -80, }, }, }, } return { name = "lm-compose-test", version = "1.00", comment = "Goodies that demonstrate composition.", author = "Hans and Mojca", copyright = "ConTeXt development team", compositions = { ["lmroman12-regular"] = compose, } } \stoptyping Of course this assumes some knowledge of the font metrics (in base points) and \UNICODE\ slots, but it might be worth the trouble. After all, one only needs to figure it out once. But keep in mind that it will always be a kludge. A slightly different way to define such compositions is the following: \starttyping local defaultunits = 193 - 30 local compose = { DY = defaultunits, -- [0x010C] = { DY = defaultunits }, -- Ccaron -- [0x02C7] = { DY = defaultunits }, -- textcaron } -- fractions relative to delta(X_height - x_height) local defaultfraction = 0.85 local compose = { DY = defaultfraction, -- uppercase compensation } return { name = "lucida-one", version = "1.00", comment = "Goodies that complement lucida.", author = "Hans and Mojca", copyright = "ConTeXt development team", compositions = { ["lbr"] = compose, ["lbi"] = compose, ["lbd"] = compose, ["lbdi"] = compose, } } \stoptyping Of course no one really needs this because \OPENTYPE\ Lucida fonts have replaced the \TYPEONE\ versions. ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl ----------------------------------------------------------------- ___________________________________________________________________________________ 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] 4+ messages in thread

If you're referring to the private-use restriction: Adobe allows private/personal modifications for most fonts, so I could get away with making small fallbacks, etc. In the end, I may very well go with a company like Adobe for just this reason. (On the other hand, all of their optical sized book fonts are made by the same designer and have the same feel ... I'd like to try something different if I can find it). If you're referring to finding a font that has all the requisite characters: Hardly any HQ commercial text font for books has the requisite characters (mostly but not all in the Latin Extended Additional block). TeX-Gyre has the chars (I lobbied for them some years ago) but for the current project T-G is not really an option. >> components I need are there (macrons, dots, etc).

Indeed. OTOH, I just found this wonderful (+very-expensive) Dutch typeface that is still(!) only available in Type1/ttf format.

I remember that we had to use an expensive Dutch font once (more than 1000 euro for a few files) that was so bugged with respect to its encoding (glyphs all over the wrong places) that I had to make a special enc vector for it. The vendor didn't even bother to consider the fact that the font could be bugged (was probably mostly used in a choose each glyph by click and point from a matrix mode).
