Hi, I was wondering, it it technically difficult to include a specific xobject (xform) from a pdf file (not so much different from including a page) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

Re: [tex-k] Dvips fix for font in EPSF improperly downloaded
by Tomas G. Rokicki 24 Jan '05

All your points are good, but I clain the "fix" is still an improvement, and for that reason I am leaving it in there. Perhaps I am naive, but if someone gives me an environment in which there are multiple, and distinctly different, fonts, with the same /FontName, I claim all bets are off. I have encountered this before and it's not a good situation. At this time I simply don't have a solution for a case like this. On the other hand, I do agree that it is better to rename the TeX fonts if we will partially subset them. I believe we should do this (assuming technically we can make it work; I do not know that we cannot, nor do I know of specific issues, but I would not be surprised if this breaks something). Of course there are legal issues with renaming a font too, most likely. :-) This is something to consider for the next release (not only of dvips but also of pdftex, I believe). But I believe this is a substantial change to a piece of code that I am simply not familiar enough with to mess with. I do know that I have had in the past substantial problems with just changing the UniqueID of the font; different interpreters were very unhappy with some of the changes I made and I had to back them out. But that's just a technical issue. On the legal issue: I agree a warning may be appropriate whenever a font is included in its entirety. Right now dvips turns a deaf ear to these issues, but it is perhaps time for it to support at the very least a warning message. Another alternative is to run all included graphics through a companion interpreter that's been configured to only collect information on what characters and what fonts are used (probably by redefining show and a few other operators). But this is another substantial undertaking. Just so we are very clear: is it your position that this change that was made should be reversed? Or improved before the next release? Both of these positions would be troublesome for me. If it's just a question of, here's some additional issues to consider and let's try to get a solution to them as quickly as possible, I could not agree more. I must say that I've had no indication that the problems you mention are severe (i.e., causing problems for people), but perhaps that is because I don't follow most of the TeX groups. I believe this is a discussion that we should have as part of a larger group, so I am happy to have gotten your note, and I hope our collected wisdom on these groups will steer us all in the appropriate direction. But for now I've got to get a point release out the door. -tom

I send a copy to ntg-pdftex(a)ntg.nl because I don't know how pdftex deals with fonts in embedded PDF files. >>>>> "Tomas" == Tomas G Rokicki <rokicki(a)CS.Stanford.EDU> writes: > I just submitted a fix for the problem where a document includes a > figure that uses a downloaded PostScript font, and that same font > is also used by the main document itself. Dvips was partially > downloading the font in this case when it should have downloaded > the entire font. It now does download the entire font. If I understand you correctly, you want to put the entire font into the output file if the /FontName of the font in the included eps-file is the same as a font used by TeX (the /FontName in psfonts.map). This will solve a few problems but not all. The main problem is that this solution assumes that a font in an embedded eps file and a font in texmf with the same /FontName are identical. But unfortunately we cannot rely on this. One example is /Courier. http://ms25.ath.cx/courier.pdf shows the difference between /leftquote in URW Courier and IBM Courier provided by XFree86 (/usr/X11R6/lib/fonts/Type1/cour.pfa). If you have problems downloading the file, let me know. Both have "/FontName /Courier def" but they are totally different. Another problem are the free URW fonts. They are under GPL and someone added cyrillic glyphs to the fonts. The modified fonts are distributed with ghostscript. When I looked into them, they still needed some refinement. Walter Schmidt maintains the original URW fonts on CTAN for exactly this reason. Assume that someone creates an eps file using the cyrillic glyphs from the gs fonts, does it really help if dvips include the entire font from the the texmf tree (which does not have cyrillic glyphs)? I think it's better not to touch eps files if possible. People expect that if they can be printed, they can be included into a TeX document. In most cases you get better results if you replace an embedded font by one provided by a TeX distribution but in some cases the result might be not what people expect. Checking the /UniqueID would minimize the risk but for fonts under GPL I wouldn't even rely on this. Isn't it better to rename the TeX fonts (the fonts mentioned in dvips.map)? For instance, from psfonts.map: bchb8r CharterBT-Bold "TeXBase1Encoding ReEncodeFont" <8r.enc <bchb8a.pfb When loading a font, replace "/CharterBT-Bold" by "/bchb8a" and then "/bchb8a findfont" instead of "/CharterBT-Bold findfont". There are some legal problems as well. If the user requires subsetting in psfonts.map and for some reason the entire font is included, there should at least be a warning message on screen. Some font suppliers disallow distribution of files containing entire fonts. Your approach leads to smaller files. I like this, of course. Maybe checking the /UniqueID is sufficient if we assume that people providing modified fonts are clever enough to change the /UniqueID as well. I must admit that I don't know whether you already do this. At the DANTE-2003 I had a discussion about problems like this with Walter Schmidt. At this time he was thinking about changing /FontName in the free URW fonts on CTAN, but I disliked this approach because it only solves problems with the fonts he maintains.

character protrusion with the first letter in a paragraph
by The Thanh Han 19 Jan '05

19 Jan '05

Hi, I have been thinking of the question how to make char protrusion work with the first char of a paragraph. The simplest (and quite robust) solution can be as follows: when considering whether a marginal kern should be inserted, we skip certain kinds of `invisible' node (like adjust node, penalty node and the like). Now to make it work with the first char of a par, we also skip null boxes (box with zero dimen and empty contents) at the left margin. The question is whether such behaviour is ``correct'', and what surprises it can bring in certain situations. Thanh
