Snapshot 20070307

10 May '12

Hi all, I decided to do a snapshot now instead of waiting for friday, because I want to start concentrating on something else besides font support issues. What's new: * Non-CID PostScript-based Opentype fonts are now combined over the entire document, and properly subsetted. The code is borrowed from xdvipdfmx with some minor adjustments Adding support for CID-keyed OpenType fonts would not be hard but at the moment I lack example input (and incentive). * A small extension to the virtual fonts structure: you can use f.fonts[1] = { 'id' = 38} to do a backreference to a previously defined font. This saves quite a few computations * There was a bug in the handling of \leaders in the output whereby it's width was taken to be twice what it should be while writing to the PDF, fixed now. * The font inclusion code is cleaned up a bit by Hartmut. * Some compilation problems were fixed. * There is (quite a bit of) debugging information printed out when OTPs are in use, because I am tracking down a bug reported by Idris. The input of each and every OTP step is shown on the terminal in a line line this: [57902][1568][58423][1568][58408][1568][58921] those are the decimal values of ocp i/o characters. If you don't need them, don't worry about it. Happy TeXing, Taco ----- Downloading and installation details: If you go to https://foundry.supelec.fr/frs/?group_id=10 you will see that there are three new released files: * luatex-snapshot-20070307.tar.bz2 This is the source tree. * luatex-snapshot-20070307-win32.zip A cross-compiled (mingw) windows binary. This is a web2c based binary, so it needs a texmf.cnf file (It will NOT work if you have only miktex installed). * luatex-snapshot-20070307-linux-i386.tar.bz2 An intel 32 linux binary (2.6.17)

letterspacing and (no) ligatures
by Robert 18 Sep '11

18 Sep '11

Hi, here are two bugs: * in pdftex, \letterspacefont does not disable the ligatures, but this is what happens in luatex. * neither \tagcode nor \pdfnoligatures seem to have any effect (for non-letterspaced fonts, that is). Example: \input luaotfload.sty \font\x="Latin Modern Roman:+liga;+tlig" at 12pt \tagcode\x`\f=-1 % no effect \pdfnoligatures\x % ditto \x fi -- \letterspacefont\y\x 100 % killing the ligatures \y fi -- \bye Best regards, -- Robert

Fwd: [poppler] [PATCH] Fixup LaTeX composed characters
by Martin Schröder 25 Mar '11

25 Mar '11

FYI. Don't ask me what's the problem with our PDF seems to be... ---------- Forwarded message ---------- From: Tim Brody <tdb2(a)ecs.soton.ac.uk> Date: 2011/3/25 Subject: [poppler] [PATCH] Fixup LaTeX composed characters To: poppler(a)lists.freedesktop.org Hi All, Attached is a patch to address the previous problem I wrote about with pdflatex-produced PDFs that contain overlapping-diacritics/accents. This patch contains: - a table of diacritic to Unicode combining character code-points - if an overlapping character is detected checks whether the first (in stream-sequence) character is in the table - pops the diacritic off the word - appends the diacritic to the character as a Unicode combining character This does not fix \b{o} or \d{o} because TeX places them on the next line (so aren't detected as overlapping). Yes, this is an issue with pdflatex but there are 100,000s of TeX-produced PDFs for which we don't have source for ... -- All the best, Tim. _______________________________________________ poppler mailing list poppler(a)lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/poppler

Using .ttc fonts with lua(la)tex in mactex 2010
by Beingalink 07 Mar '11

07 Mar '11

I just decided to investigate this problem a bit deeper and finally found out that doing some manual changes in otfl-names.lua, enables me to use these fonts again. I tested it using "Hoefler Text.ttc". The entries in otfl-names.lua regarding hoefler text are: -------------------------------------------------------- { ["familyname"]="Hoefler Text", ["filename"]={ "Hoefler Text.ttc", 0 }, ... }, { ["familyname"]="Hoefler Text", ["filename"]={ "Hoefler Text.ttc", 1 }, ... }, { ["familyname"]="Hoefler Text", ["filename"]={ "Hoefler Text.ttc", 2 }, ... }, { ["familyname"]="Hoefler Text", ["filename"]={ "Hoefler Text.ttc", 3 }, ... }, -------------------------------------------------------- I added the actual path to the .ttc file and thus changed the entries to this: -------------------------------------------------------- { ["familyname"]="Hoefler Text", ["filename"]={ "/Library/Fonts/Hoefler Text.ttc", 0 }, ... }, { ["familyname"]="Hoefler Text", ["filename"]={ "/Library/Fonts/Hoefler Text.ttc", 1 }, ... }, { ["familyname"]="Hoefler Text", ["filename"]={ "/Library/Fonts/Hoefler Text.ttc", 2 }, ... }, { ["familyname"]="Hoefler Text", ["filename"]={ "/Library/Fonts/Hoefler Text.ttc", 3 }, ... }, -------------------------------------------------------- Doing these changes let me do the following in lualatex which didn't work before: \setmainfont[Ligatures=TeX]{Hoefler Text} I'm not a programmer so I'm not sure if the changes I did are actually safe to adopt but perhaps this can help someone to fix this issue in the repository so it will work in future versions of lua(la)tex. To be sure, I'll paste the non-shortened excerpt with the changes I did here: { ["familyname"]="Hoefler Text", ["filename"]={ "/Library/Fonts/Hoefler Text.ttc", 0 }, ["fontname"]="HoeflerText-Regular", ["fullname"]="Hoefler Text", ["names"]={ ["family"]="Hoefler Text", ["fullname"]="Hoefler Text", ["psname"]="HoeflerText-Regular", ["subfamily"]="Regular", }, ["size"]={}, ["slant"]=0, ["weight"]=5, ["width"]=5, }, { ["familyname"]="Hoefler Text", ["filename"]={ "/Library/Fonts/Hoefler Text.ttc", 1 }, ["fontname"]="HoeflerText-Black", ["fullname"]="Hoefler Text Black", ["names"]={ ["family"]="Hoefler Text", ["fullname"]="Hoefler Text Black", ["psname"]="HoeflerText-Black", ["subfamily"]="Black", }, ["size"]={}, ["slant"]=0, ["weight"]=7, ["width"]=5, }, { ["familyname"]="Hoefler Text", ["filename"]={ "/Library/Fonts/Hoefler Text.ttc", 2 }, ["fontname"]="HoeflerText-Italic", ["fullname"]="Hoefler Text Italic", ["names"]={ ["family"]="Hoefler Text", ["fullname"]="Hoefler Text Italic", ["psname"]="HoeflerText-Italic", ["subfamily"]="Italic", }, ["size"]={}, ["slant"]=-13.5, ["weight"]=5, ["width"]=5, }, { ["familyname"]="Hoefler Text", ["filename"]={ "/Library/Fonts/Hoefler Text.ttc", 3 }, ["fontname"]="HoeflerText-BlackItalic", ["fullname"]="Hoefler Text Black Italic", ["names"]={ ["family"]="Hoefler Text", ["fullname"]="Hoefler Text Black Italic", ["psname"]="HoeflerText-BlackItalic", ["subfamily"]="Black Italic", }, ["size"]={}, ["slant"]=-13.5, ["weight"]=7, ["width"]=5, },
