Luatex 1.08.0 announcement
by luigi scarso 28 Oct '19

28 Oct '19

============================================================== LuaTeX 1.08 2018-08-28 ============================================================== (1) This release is a prelude to 1.10, the next stable iteration of LuaTeX after version 1.00. (2) Lua 5.3 is now considered to be default and we might use 5.4 in version 1.10. There are no real functional changed expected. You still need to rename the binary for 5.3! (3) Binary mode is no longer available in MPlib but it is still available in stand alone MetaPost. This simplifies compilation and reduces dependencies. (4) The dependency on Poppler for pdf image inclusion has been removed. We now use a small dedicated library written by Pawel Jakowski. We no longer need c++ compilers. We're in the process of making it behave well on all platforms. It has been tested on intel platforms. (5) We know that there can be some (alignment) issues with the arm platform but these are looked into. Therefore, later this year we will release 1.09. Version 1.10 is planned for TeXlive. We hope that ffi works ok on intel and arm platforms at that point. (6) There have been some extensions to the Lua libraries and some callbacks have been added. Also, a few new primitives have been introduced. The documentation mentions the stable extensions. (7) There are the usual bug fixes and cleanups but there have been no real fundamental changes in the API. The LuaTeX team

attachments in PDF/A-3
by Pablo Rodriguez 22 Apr '19

22 Apr '19

Dear list, my sample to add attachments to a PDF/A-3 valid document is the following: \setuptagging[state=start] \setupbodyfont[30pt] \setupbackend [format=PDF/A-3a, intent=sRGB IEC61966-2.1, profile={sRGB.icc,default_gray.icc}, level=0] \setupcolors[pagecolormodel=auto] \setupinteraction[state=start] \starttext \startTEXpage[offset=1em] an attachment\attachment[file=xml-mkiv.pdf] \stopTEXpage \stoptext There are five reported errors when tested with the latest development version of veraPDF (http://downloads.verapdf.org/dev/verapdf-installer.zip): - Annotation should have /F value (https://github.com/veraPDF/veraPDF-validation-profiles/wiki/PDFA-Parts-2-an…); unless their Rect key value 1 equal to value 3 and value 2 equal to value 4, or the annotation subtype is /Popup or /Link. - Although not reported, the /F value should conform these considerations: If present, the F key's Print flag bit shall be set to 1 and its Hidden, Invisible, ToggleNoView, and NoView flag bits shall be set to 0. https://github.com/veraPDF/veraPDF-validation-profiles/wiki/PDFA-Parts-2-an… - Annotations need an appearance dictionary (https://github.com/veraPDF/veraPDF-validation-profiles/wiki/PDFA-Parts-2-an…); unless the same exception for the /F value apply. - The /EmbeddedFile dictionary should specify the MIME type in its /Subtype entry (https://github.com/veraPDF/veraPDF-validation-profiles/wiki/PDFA-Parts-2-an…). - The /AFRelationship key is missing from the /Filespec dictionary (https://github.com/veraPDF/veraPDF-validation-profiles/wiki/PDFA-Parts-2-an…). Possible values are: Source, Data, Alternative, Supplement, EncryptedPayload, FormData, Schema or Unspecified (from https://www.pdfa.org/wp-content/uploads/2018/10/PDF20_AN002-AF.pdf). - The /Filespec lacks association with the PDF document or any of its parts, such as pages (https://github.com/veraPDF/veraPDF-validation-profiles/wiki/PDFA-Parts-2-an…). From https://www.pdfa.org/wp-content/uploads/2018/10/PDF20_AN002-AF.pdf, it seems that either the /Catalog or a /Page dictionary (there are other ones, but I would limit attachments in ConTeXt to those two [if not to the /Catalog itself only]) should contain an /AF entry with the reference to the /Filespec object(s). I assume that the value type for the /AF entry is an array of one or multiple object references. These are all the issues veraPDF finds when validating the PDF document generated from the source above. I hope it helps. Many thanks for your help, Pablo -- http://www.ousia.tk

Quoting problems in grph-con.lua
by Kevin Boulain 21 Apr '19

21 Apr '19

Hi, >From my understanding, there are some superfluous quotes in context/base/mkiv/grph-con.lua, cancelling the proper quoting done by validcommand in context/base/mkiv/util-sbx.lua. For my document, it tries to run something like (the space in the 'Google Drive' directory breaks the generation): inkscape ""[...]/Google Drive/[...].svg"" --export-dpi=600 --export-pdf=""[...]/Google Drive/[...].svg.pdf"" Applying this patch fixes the double quotes issue: local runner = sandbox.registerrunner { name = "svg to something", program = "inkscape", template = longtostring [[ - "%oldname%" + %oldname% --export-dpi=%resolution% - --export-%format%="%newname%" + --export-%format%=%newname% ]], However, it seems there are more similar quotes in the other templates of the file. mtx-context | current version: 2019.04.16 08:54 (I hope this is the proper way of reporting.) Regards.

Hi Hans, the new luametatex release doesn't work with the \pageinjection command. The resulting pdf shows the same content on all pages, e.g. in the following example I get the first page twice. \starttext Before \pageinjection [empty] After \stoptext Wolfgang
