Snapshot 20070307
by Taco Hoekwater 10 May '12

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)

Hi, It seems that commits 4019 & 4021 have finally fixed the use of Snow Leopard's .ttc system fonts! Best wishes, Taco

[***SPAM***] \underbrace and \overbrace strangeness with Cambria Math
by Graham Douglas 01 Dec '10

01 Dec '10

Hi All With the following minimal test file % test file \documentclass[11pt,twoside]{article} \usepackage{unicode-math} \begin{document} \setmathfont[math-style=TeX]{Cambria Math} \setmainfont{Cambria} $$ \underbrace{ a+b+\cdots+z }_{26} \overbrace{ 1+2+\cdots+100 }^{5050} $$ \end{document} I see odd results with Cambria Math (PDF sent with this e-mail) This is LuaTeX, Version beta-0.65.0-2010113019 (format=lualatex 2010.11.15) 30 NOV 2010 23:00 Package: fontspec 2010/11/07 v2.1d Package: unicode-math 2010/09/27 v0.5b Using regular Computer Modern there are no problems. Does anyone else see the same issue with Cambria Math? If I need to report this elsewhere (lualatex-dev) I'll do so. Cheers Graham

pdftexversion, OmegaVersion etc.
by Khaled Hosny 30 Nov '10

30 Nov '10

I was wondering, since luatex is not a direct replacement of pdftex, omega or aleph, what is the point of having such primitives? Wouldn't it be more cleaner of they are removed or is there any use for them? pdftexversion pdftexrevision OmegaVersion AlephVersion Alephminorversion Alephrevision Alephversion Omegaminorversion Omegarevision Omegaversion eTeXVersion eTeXminorversion eTeXrevision eTeXversion Regards, Khaled -- Khaled Hosny Arabic localiser and member of Arabeyes.org team Free font developer

Q: image size
by Patrick Gundlach 30 Nov '10

30 Nov '10

Hi, what is the difference of img.width and img.xsize? (reference manual 4.5.2 img.keys) For example, the cow.pdf gives me img.width = 18646779 and img.xsize = 18089984 What are the units? img.width is in sp, what about img.xsize? Patrick

node.next(), node.prev()
by Patrick Gundlach 29 Nov '10

29 Nov '10

Hi, is there a difference between -- assume that x is a node n = x.next and n = node.next(x) ? I guess that node.prev(n) needs the prev pointer set, right? Patrick

Include cropped PDF files
by Patrick Gundlach 29 Nov '10

29 Nov '10

Hi, I'd like to include cropped PDF files in my document. What is the correct way? Currently I use something like this: image = img.scan{filename = filename , pagebox = "crop" } img.node(image) Is it safe to add pagebox = "crop" to _all_ image inclusions? Any other, better way? Patrick
