Type3 fonts and the way to go

Aloha,The Thanh Han posted:>I spent a few hours playing with type3 fonts, but was not able to create>a type3 font that uses another font (type1). It seems that the text>operators somehow doesn't work inside the CharProc stream for type3>fonts.> ...>But anyway, if someone is interested in this issue, please>have a look into the pdf I created, maybe I did something wrong.-Ressources, as Hans Hagen pointed out, the /Ressources of the pageand therefore object 13 need both /Fonts defined. -Encoding, as you're defining chars 97 and 98 and use 'A' and 'B' which are 65 and 66 in my StdEncoding table you won't get that muchpage impression...-Scaling, you need to reread the chapter about text space details. You aredefining a /FontMatrix of [0.001 etc.] which gives you a 1000x1000 glyphcoordinate system. For /A you use this (750 re), but for /B you definea very small /F1. I don't have a facility to compile your f2.tex with an recent pdftex, soi changed the abovementioned points directly in the f2.pdf. Here are the objects with the changes:13 0 obj << /Font << /F2 10 0 R /F1 9 0 R >> /ProcSet [/PDF /Text] >> endobj 10 0 obj << /Type /Font /FontBBox [0 0 1000 1000] /FirstChar 65 /Widths [750 750] /FontMatrix [0.001 0 0 0.001 0 0] /Encoding 5 0 R /CharProcs 4 0 R /Resources 6 0 R /LastChar 66 /Name /F2 /Subtype /Type3 >> endobj 5 0 obj << /Type /Encoding /Differences [65 /A /B] >> endobj 2 0 obj << /Length 35 >> stream 1000 0 d0 BT /F1 900 Tf (B) Tj ET endstream endobj As far as i understand f2.tex it should be very easy to change (except for the /Ressourcesentry). Wishing a happy day LOBI

pdftex1.21a build, linker problem
by andreas.lobinger＠freenet.de 12 Feb '05

12 Feb '05

Aloha, i'm building pdftex on a sort-of standard sparc-sun-solaris2.8. I get a linker problem in building ctangleboot ... /bin/sh ../libtool --mode=link gcc -o ctangleboot ctangleboot.o cwebboot.o lib/lib.a ../kpathsea/libkpathsea.la -lm gcc -o ctangleboot ctangleboot.o cwebboot.o lib/lib.a ../kpathsea/.libs/libkpathsea.a -lm ld: fatal: symbol `main' is multiply-defined: (file ctangleboot.o and file lib/lib.a(main.o)); ld: fatal: File processing errors. No output written to ctangleboot collect2: ld returned 1 exit status gmake: *** [ctangleboot] Error 1 It seems, that the build process is assuming a ld that quietly suppresses multiply defined objects. This shouldn't be so. Wishing a happy day LOBI

[ pdftex-Patches-257 ] Experimental patch for pdftex character protrusion
by noreply＠sarovar.org 09 Feb '05

Patches item #257, was opened at 2005-01-10 21:43 You can respond by visiting: http://sarovar.org/tracker/?func=detail&atid=495&aid=257&group_id=106 Category: None Group: Unstable (example) >Status: Closed Resolution: None Priority: 3 Submitted By: Hartmut Henkel (hhenkel) Assigned to: Nobody (None) Summary: Experimental patch for pdftex character protrusion Initial Comment: Normally items inside a \hbox are not considered for protrusion. With this experimental patch also nested \hboxes at the left and right margin are recursively searched for items with \lpcode or \rpcode, and the outmost containing boxes are protruded correspondingly. This seems to be practical e. g. if an elevated \footnote{foo} (LaTeX) index happens to be at the right margin; in this case the footnote index normally is placed too far inward the line. This disturbance was detected by Peter Muthesius in an de.comp.text.tex news thread "pdfcprot und Ziffern am rechten Rand" started Sat Jan 08 14:05:23 CET 2005. Rough experimental patch, rudimentarily tested with left and right protrusion, see test file xx.tex with output xx.pdf. Just for discussion. No warranty. Have fun!

The nested list will be recursively searched until a non-skipable item (protrusion character, other character, or list end) is found. * Try to solve left protrusion at paragraph start with \parindent=0pt,by selectively skipping over TeX's empty \hbox{} there. * Protrusion character search by 2 new functions find_protchar_left() and find_protchar_right(), and simple stack.

[ pdftex-Bugs-199 ] font expansion: characters may vanish

I only managed to achieve this effect with extremely large font sizes, which may or may not be related (it could also be that I didn't find the `magic' \hsize). If you force the characters to shrink even more, for example by setting \hsize to 120pt in the latter test file, the unexpanded font will be used, thus printing the characters over each other.

If my guess is right, pdftex tries to use the font `cmr17-Extend_0', which (incorrectly) translates into the base font.

Sorry about that. It is not a pdftex bug, but appears to be a bug in Acrobat Reader 6. (Just to tell you what I saw:) At zoom level 200% or larger, the font most shrunk (Extend_100) is not visible on screen. That is, in the first example, I only see "See y e", in the second, nothing at all. However, if I zoom out, the characters re-appear. Sorry for not zooming out earlier.

[ pdftex-Bugs-274 ] \unhbox kills protrusion

Bugs item #274, was opened at 2005-01-31 03:09 You can respond by visiting: http://sarovar.org/tracker/?func=detail&atid=493&aid=274&group_id=106 Category: hz Group: None >Status: Closed >Resolution: Fixed Priority: 5 Submitted By: Robert (schlcht) Assigned to: The Thanh Han (hanthethanh) Summary: \unhbox kills protrusion Initial Comment: Protrusion will break when boxes containing protruded characters are \unhbox'ed. I've stumbled upon this when using edmac/ledmac, which decomposes each paragraph into lines, then reassembling them. I wasn't sure whether protrusion is supposed to survive this treatment but it does if one uses \unhcopy instead of \unhbox. Here's a greatly reduced example: %-------------------------------------------- \font\testfont=cmr10 \testfont \pdfprotrudechars=2 \rpcode\font`\-=1000 \parindent0pt \hsize=126pt \newbox\testline \newbox\testbox % \setbox\testbox\vbox{% Margin kerning is the adjustments of the characters at the margins of a typeset text. } \loop\ifvbox\testbox \setbox\testline=\vsplit\testbox to\baselineskip \unvbox\testline \setbox\testline=\lastbox \hbox to\hsize{\unhcopy\testline}% OK \hbox to\hsize{\unhbox\testline} % not OK \repeat \bye % -------------------------------------------------- Regards, Robert <w.m.l[at]gmx.net> ---------------------------------------------------------------------- Comment By: Martin Schröder (oneiros) Date: 2005-02-09 12:35 Message: Logged In: YES user_id=421 This has been fixed in 1.21a ---------------------------------------------------------------------- Comment By: Hartmut Henkel (hhenkel) Date: 2005-01-31 23:34 Message: Logged In: YES user_id=929 There seems to be one place in hz.ch where \unhbox and \unhcopy are treated differently: %@x [1100] - margin kerning %while link(tail)<>null do tail:=link(tail); %@y %if c = copy_code then begin % while link(tail)<>null do tail:=link(tail); %end %else while link(tail) <> null do begin % r := link(tail); % if not is_char_node(r) and (type(r) = margin_kern_node) then begin % link(tail) := link(r); % free_avail(margin_char(r)); % free_node(r, margin_kern_node_size); % end; % tail:=link(tail); %end; %@z After just commenting this piece out (as shown), both \unhcopy and \unhbox do protrusion ok.
