New Didot-point
by Nagy Bence 20 May '05

20 May '05

Dear All, I have a new tipometer now, and I wondered, that by Rotring Didot-point is no more 0,376 but 0,375 mm. Actually the new Didot-size is more komfortable, because one Cicero is exactly equal to 4,5 mm, two Cicero to 9 mm. I have attached a small patch, which introduces two new units: nd (new didot) and nc (new cicero). Maybe we have to follow the sounds of new times. Any comments? Greetings, Bence -- Nagy Bence | Tipográl.hu

Hi, I have uploaded a new pdftex snapshot to pdftex.sarovar.org/src djgpp is also available (pdfetex only) I didn't change the version and banner, as Martin will decide what to be there when he makes an official release. Now I recognize that I forgot the microinterval patch from Taco. Sorry about that, will upload another one tomorrow Thanh

There's some interesting discussion of it in comp.text.tex ~1999, w/ one of the observations being that using stroked lines improves 300dpi output. FWIW, if one turns on ``Smooth line art'' in Adobe Acrobat 5 (probably 6 and 7 too) there's not that much difference in the appearance of the rendering of the square root rule / character in Hans' example file (which is hinted at in the afore-mentioned discussion, and noted by Hans in a post on the ConTeXt list as making this matter worth re-examination). At some magnifications things are about identical, at others one gets a double-pixel medium grey line, and the other gets a single-pixel dark grey line. Hopefully at some point in time we'll just get high-resolution displays everywhere and this sort of thing will cease to be an issue. Isn't there a Unicode slot for fraction bar (I know the Mac encoding has a slot for fraction slash)? How is this handled in the soon-to-be-released stix fonts? (http://www.stixfonts.org) William

I think ``horribly'' is a bit extreme. Rules are drawn like any other filled rectangle, and can be set to be anti-aliased in viewers which support that setting for graphic objects. Using a character is an interesting idea, but has difficulties as Hans noted. Just replacing it w/ a stroked line would be an alternative worth considering IMO. William

pdftex-1.21b snapshot
by The Thanh Han 14 May '05

14 May '05

Hi, I have uploaded a snapshot of pdftex to pdftex.sarovar.org/src djgpp is also available (pdfetex binaries only). This is a bug-fix release that has all pending patches by Hartmut. The png patch by Taco has also been integrated. A quick summary from NEWS (Martin will make them more meaningful when an official version is released): ,-------- | - patch for PNG support by Taco & Hartmut (259) | | - ignore marginal kerns while unhboxing (292) | | - added \leftmarginkern & \rightmarginkern (292) | | - removed \pdfmovechar (294) | | - added \pdftracingfonts (304) | | - make \pdfxform work with box > 255 (310) | | - added \pdfxformname (requested by Pawel) | | - fixed problem with fonts on solaris (315) | `-------- There are still 2 pending problems: 1) the problem with truetype fonts when a unicode is mapped to 2 or more glyphs. I let pdftex fail in such a cas but still don't know what would be the right thing to do. 2) the problem with dangling object: I changed a few things to fix it but pdf inclusion may be broken now; please do some testing if you can. With the test files by Hartmut at sarovar: now there is a dangling object in yy2.pdf, which is expected if the font used in the included pdf is not used in the main document. Getting rid of this doesn't seem easy. Thanh
