For the present though, one can make do +with virtual fonts based on the cm fonts. As a step in this direction, 55 +dm (dyslexic modern) virtual fonts have been created from TeX text mapped +cm fonts. These include 58 characters referenced by numbers in the range +192 to 255. The character number has been based on ISO 8859/1, details of +which were sent to me by Chris Thompson. The TeX community needs urgently +to establish a decent standard for character mappings 128-255. The 58 +additional characters in the dm fonts are either single characters remapped +or character pairs possibly with positioning. TeX was used with the fonts at +16pt to obtain character dimensions, which avoids some possible rounding +problems. The width of the virtual character is exactly the same as the width +of the last character in its expansion. This simplifies DVI-DVI conversion. +Kerning for the new characters is based on the principal character in the +virtual character. Thus each accented letter is treated in terms of kerns +as though it were the unaccented letter. Those who wish more subtle kerns +may modify the TFM files with TFtoPL and PLtoTF. The check sum of the dm +font is obtained from that of the corresponding cm font by adding 4. + +In addition to the dm virtual fonts, this distribution also provides +the DVI-DVI translation program DVF.EXE. It has the 55 VF's built in. +For a DVI file which contains references to the dm fonts, one may run +DVF on this file to translate these references into their cm equivalents. + +These are experimental fonts and programs. Please send comments, bug reports, +etc., to + Wayne Sullivan + WSULIVAN@IRLEARN.bitnet +(14 May 1990) + +Please destroy the earlier code page 850 version of DVF. DVF03 has incorrect +kerning for certain characters. |
