Hi folks, Recently, I started using the EMTEX 3.0 package. In general the program runs beautifully. However, I encountered a problem that I wishes to present to you. The problem is related to the use of fonts, and if I'm not totally mistaken it is not only restricted to EMTEX. If one wishes to make overlays with slitex and one uses the \invisible command an error-message occurrs while previewing or printing the slides. This error-message is about slitex not being able to find the invisible fonts. Since I didn 't generate these fonts I find the error message understandable. One way of solving the problem is by generating the fonts, but I find this an unsatisfactorary solution. The invisible .fmt fonts should be sufficient since they contain the size information of the printer, which is all that is needed to print the "invisible characters". Can anyone tell me how the latter solution can be implemented. Robert Huis in 't Veld | Phone: +31-40-473368, Fax. +31-40-448375 Eindhoven University of Technology, Depr. of Electr. Eng.

In PK format, they take up maybe 512 bytes each, maybe a little more (I don't know since on the disk where we keep our TeX fonts, files are allocated 5 512byte blocks at a time). The width information in the FMT file is available only to TeX, not to the drivers; the only way for the drivers to handle the solution you would want is to either (a) have the driver insert blank space for all missing characters (which is a reasonable solution, but I wouldn't want a driver doing this without warnings and I wouldn't want to get warnings about every invisible font I use) or (b) give the driver an auxiliary file listing all the invisible fonts so it knows to read the TFM data and just leave space for those fonts (and yes, reading the TFM files would be necessary to avoid having PKs since that information is not in the DVI file). From an implementor's standpoint, the best solution is to simply have PK files with empty rasters; yes, it takes up a bit more space, but there are certain pieces of code in the driver that this will encourage (the most notable of which is detection of a character with an empty raster. The Chess fonts on ymir.claremont.edu, for example, have a single character which is an empty glyph which causes grief for more than one driver that I've had experience with (the only one that comes to mind off hand is dvidis which may or may not have been fixed in the intervening time since I last used it)). -dh --- Don Hosek TeX, LaTeX, and Metafont support, consulting dhosek@ymir.claremont.edu installation and production work. dhosek@ymir.bitnet Free Estimates. uunet!jarthur!ymir Phone: 714-625-0147 finger dhosek@ymir.claremont.edu for more info

Refer to the dvidrv.eng document file in emTeX. This contains information about font substitution files. You will need a /ps (font substitution file) command in your configuration file (.cnf). The following line in a font substitution file will replace characters by a white space. This is what you want for invisible characters. i* -> * /w % invisible, white This will work with all emTeX drivers, so you don't need separate invisible fonts. If you are using a non emTeX driver (like me), you will probably need to create the invisible pk font files. See the mfjob program in emTeX. I have written a job file to create the missing SliTeX fonts for hplaser, which has the same mode def as one I found for imagen, which I believe is also used for the Apple LaserWriter. I am currently using emTeX's hplaser fonts with dvips and an Apple LaserWriter. -- Russell Lang Email: rjl@monu1.cc.monash.edu.au Phone: (03) 565 3460 Department of Electrical and Computer Systems Engineering Monash University, Australia

On the subject of SliTeX, could someone please tell me where one can get the special transparencies mentioned in the LaTeX manual (p 133): "These pages are called *color layers*. Copying each of them onto a special sheet that produces a transparency of the appropriate colour (such sheets are commercially available in an assortment of colours) and laying the three transparencies atop one another produces the desired three-colour slide." I've asked in Dublin about these sheets, and none of the stationers has ever heard of them.

However this problem does not occur only with PK format fonts. Recently I hacked up a quick and dirty SliTeX that uses PS fonts (who worries about pixel rounding at 24pt) for OzTeX. Now if the driver knew that some PS fonts are supposed to be invisible (by consulting a configuration file or something) then there'd be no problem. If I'm mistaken and the driver in OzTeX can already do this, let me know. No, don't ask me for the macros, I still have to find a bit of spare time to get the macros to use the PS bullet for items instead of the cmsy bullet. And other minor things.

Can anyone tell me how > the latter solution can be implemented. If you're using the emTeX drivers, you need only the TFM files for the *visible* SliTeX fonts. The invisible fonts can be mapped to the visible fonts made invisible by using the drivers with a font substitution file containing the line i* -> * /w (see dvidrv.doc). [Unfortunately, you cannot use other fonts starting with an `i'.] The newest emTeX release (20-Aug-1990) contains a MFjob job file for creating the visible SliTeX fonts.
