Re: [pdftex] Who does the releases?

Hi Martin, > Thanh, > I was surprised by the release today (learned of it through > tetex-pretest). I suggest renaming it to 1.20a-rc3 and splitting > off pdfxtex ASAP. I was told that you were not very happy with the latest upload, because it overwrote the stable sources in texlive/tetex. I am sorry to hear about that. However, I would like to clarify a few points: 1) I think that the pdftex sources are in the development branch, and they are moved to the stable branch only when Sebastian approves it. 2) I am not aware that I should not do a release. We have agreed that you will be doing/monitoring/scheduling releases. Does it mean that I should not make any release at all. Then can you please tell me how I should name my changes? 3) It's not clear to me why pdfxtex should be gone ASAP. If it should not be built by default, isn't it better to change the config files not to compile it unless an option `--with-pdfxtex' is explicitly given? 4) At the meantime, I will rename the latest sources to 1.20a-rc3 as you suggested. My next changes will be uploaded to pdftex.sarovar.org and wait there until we agree that they can be released. 5) If something goes wrong, can you please let me know directly. Best regards, Thanh

pdf(e)tex compatible with tex?
by Staszek Wawrykiewicz 11 May '04

11 May '04

I'm so sorry, but I found some incompatibilities in pdfetex in dvi mode. My silly test, attached in il1test.zip, or in case that the mailer could remove it, available from ftp:/ftp.gust.org.pl/TeX/GUST/test/il1test.zip can show you that some primitives give strange output, e.g. not expected headlines and footers using pdfetex based latex format. This example can be compared with 'latex' or 'pdflatex' from TeX Live 2003 against the *current* stuff from P4 depot (pdf(e)tex 1.20b-2.1). Ps. Martin, your 'Bye' was rejected, so I'd still like to hear your opinions. Best, -- Staszek Wawrykiewicz StaW(a)gust.org.pl

easy font expansion (image inclusion)
by Akira Kakuto 09 May '04

09 May '04

Hi Thanh, I have obtained a very small "pointlike" image by \includegraphics{foo.jpg} where foo.jpg is a usual size image. Therefore I have revived previous values for arguments of "pdf_print_real" as follows: pdf_append_list(pdf_ximage_objnum(p))(pdf_ximage_list); if not is_pdf_image(image) then begin pdf_print_real(ext_xn_over_d(pdf_width(p), ten_pow[6], one_hundred_bp), 6); pdf_print(" 0 0 "); pdf_print_real(ext_xn_over_d(pdf_height(p) + pdf_depth(p), ten_pow[6], one_hundred_bp), 6); -------> pdf_append_list(pdf_ximage_objnum(p))(pdf_ximage_list); if not is_pdf_image(image) then begin pdf_print_real(ext_xn_over_d(pdf_width(p), ten_pow[4], one_bp), 4); pdf_print(" 0 0 "); pdf_print_real(ext_xn_over_d(pdf_height(p) + pdf_depth(p), ten_pow[4], one_bp), 4); Best regards Akira

Hi, When embedding a file using \pdfobj file {...} i get whateverendstream is this valid? shouldn't endstream be on its own line?

Thanks a lot. It will be better for pdf[ex]TeX to exit with an error message without causing access violation, when a user calls hz without embedding relevant fonts. Best regards Akira

easy font expansion
by The Thanh Han 07 May '04

07 May '04

Hi, I did some (quite heavy) changes on pdftex to support font expansion, so it can be used easily. So far the font expansion feature requires that user must be able to create expanded tfm (eg cmr10+10.tfm). Now font expansion can be used without expanded tfm. One can say: \font\f=cmr10 \pdffontexpand\f 20 20 5 autoexpand and pdftex will create those expanded tfm like cmr10+10, cmr10-20, etc. automatically. This also works for virtual fonts (like ptmr8t). The sources tarball is available at http://vntex.sourceforge.net/private/thanh/pdftex/pdftex-2004_05_02.tar.bz2 [to Hans Hagen: the djgpp binary of pdfxtex is avail. at the same location] I didn't submit this version to the texlive repository yet, because I changed the sources quite a lot and it can introduce new bugs. For those interested in details of automatical font expansion: 1) a tfm is expanded by copying the metrics from the base tfm, then character widths, kerns and italic corrections are adjusted. 2) for virtual fonts: nothing is changed apart from local font definitions (they are automatically expanded just like (1)). This means that some accents can be misplaced by a very small amount (0.01--0.01pt). If this amount seems too much to you, then the wokraround is to create expanded tfm manually. A minimal test file can look like: ======================================= \pdffontexpand\font 20 20 5 autoexpand \pdfadjustspacing 2 <A few long paragraphs here> \bye ======================================= Then open the pdf file in acroreader and look at File->Info->Fonts, or use pdffonts (comes from xpdf) to see whether the body font is expanded. What is font expansion good for? 1) if you care about micro-typography like even word spacing and greyness of your pages; 2) if you are typesetting narrow columns and would like to get rid of those overfull/underfull boxes or frequent hyphenations with none (or liltle) manual tweaking. Feedbacks are welcome very much. Thanh PS: this version also fixes the problem with \mag

The new pdfxTeX is compatible with Olaf's new tex.ch if you use tex.ch2 with only 5 lines: @x @d format_extension=".efmt" {the extension, as a \.{WEB} constant} @y @d format_extension=".xfmt" {the extension, as a \.{WEB} constant} @z Best regards Akira
