To use the +package, arrow.tfm must be copied to a directory where LaTeX will be +searching for .tfm files, arrow.mf must be copied to a directory where +MetaFont will be searching for MetaFont sources. The required .pk files +should be produced automatically by a dvi previewer or a printer driver. + +There are also type 1 fonts of arrow.mf in Mac and PC/Unix format so that +you can produce PDF documents easily. To use the type 1 font it must be +copied to a directory where TeX and friends will be searching for type 1 +fonts, the best place would of course be where the Computer Modern type 1 +fonts reside. + +If dvips is supposed to use the type 1 font instead of the .pk font you +must add this line to psfonts.map: + +- for Macintosh: + +arrow arrow <arrow + +- for PC/Unix: + +arrow arrow <arrow.pfb + +If you use pdfTeX instead of dvips and Acrobat Distiller you must also add +this line to pdftex.map: + +arrow <arrow.pfb + +4) Disclaimer + +The macro chemarrow.sty and the font arrow.mf are quick hacks for my own +needs, I cannot guarantee that they will work an other systems than my own. +In exchange I am publishing this package as free software which means you +can do whatever you like with it and it comes for free. I would just like +to ask that in case you do make changes und publish the package or any parts of +it to add your own name or replace it with mine. Thank you. + +Any hints and suggestions will be accepted gratefully. + +5) History + +As I was looking for new arrows I found a quite new font named cryst.mf by +Ulrich Mueller which I rather liked. After a few modifications the new font +arrow.mf was born. + +I received a macro by Andreas Hertwig with which you can typeset arrows +that will change in size. I modified this macro to my needs and replaced the +original arrows with the arrows from arrow.mf. The original macro was apparently +posted in a TeX mailing list, but its author is unfortunately unknown. So, if +you are the original author and read this I'd like to thank you for your work! + +The most time consuming and complicated part was to produce a type 1 font +from my MetaFont sources. Unfortunately there is no free software to do +this :-( +Also, if you include .pk fonts into PDF documents you won' get nice results +because Acrobat Reader renders them very poorly. Therefore it is vital to +include type 1 fonts into a PDF document :-( + +Using arrow.mp which is a slightly modified arrow.mf in combination with +MetaPost and mfplain I was able to produce graphics in the EPS format which I +imported into a demo of FontLab 3.0. After a few steps and reducing the +size to 79% I was able to save the font in type 1 format. + +6) Problems + +Unfortunately I am no expert on creating fonts. This is probably why the +arrows will show on some platforms only at 125% or larger. Below 125% there +will only be some strokes :-( + +I think if someone did a manual hinting of the font then this problem +would be remedied, but this will probably not be me because this is out of +my league and beyond the time limit of the demo of FontLab :-) + +So if there is somebody out there who is able to help me with this problem +I'd be grateful. + +7) Future versions + +To tell you the truth, I don't really know if there will be future versions +because as far as I'm concerned the package works as it is supposed to. +The direct linking of the arrow font in chemarrow.sty is maybe not so nice, +so this might be something I will change in the future. The rendering +problem of PDF documents on some platforms is also not very nice so if +some sort of solution pops up I will publish it. + +8) Thank-Yous + +- D. E. Knuth for TeX +- L. Lamport for LaTeX +- to the LaTeX3 team for LaTeX2e +- A. Hertwig for being so nice to give me the original macro +- to the unknown author of the original macro +- U. Mueller for cryst.mf + +9) Author + +Thomas Schroeder + +schroeder@ictw.chemie.uni-karlsruhe.de + +PS: Sorry for any misspellings and such, English is not my native +language :-)
