Re: [Bug: 21.5-b22] xft xemacs discards info about current dpi

giacomo> XEmacs uses FcDefaultSubstitute [1] and that's a giacomo> candidate for something consistent about that No; FcDefaultSubstitute cannot handle *your* display *at all*; it handles whatever Keith Packard thinks is the lowest common demoninator (75dpi, in fact). Also, it's not "consistent" handling; from XEmacs's point of view, fontconfig cannot possibly do that, because XEmacs knows how to display on remote displays, and may actually display on several displays with different geometries and visuals simultaneously. fontconfig cannot pick up remote display configurations automatically AFAIK; it only knows about the local display (possibly you can conditionalize---but that would be in fonts.conf!) XEmacs, on the other hand, contains a lot of logic for handling remote displays---but it assumes that the fonts it uses are supplied by (and therefore consistent with) the remote display. giacomo> most applications AND lwlib get their fonts at proper giacomo> pixelsizes, giacomo> it's difficult for me to understand why i should tinker giacomo> the system configuration In the document you quote, FcDefaultSubstitute gives 75dpi. If you want to override that, you have to override it. For a workstation that displays on a local X server, fonts.conf is the right place for overrides. Apps should not have to worry about it. Even if you do display on other X servers, the application will have to deal with them case by case, using special logic that fontconfig cannot help with _at all_. XEmacs frames currently do not contain that logic for Xft, and I'm not going to worry about it until I'm done refactoring the font handling modules. Since you say lwlib is getting the right resolution, possibly it will fall out of the refactoring naturally. -- School of Systems and Information Engineering http://turnbull.sk.tsukuba.ac.jp University of Tsukuba Tennodai 1-1-1 Tsukuba 305-8573 JAPAN Ask not how you can "do" free software business; ask what your business can "do for" free software.
