New arrow heads for chemical reaction schemes 4 February 2001 --------------------------------------------- 1) What's the name of the game? LaTeX can be used to typeset many kinds of different documents, but typesetting chemical reactions is esthetically not very pleasing because LaTeX's own arrows \rightarrow, \leftarrow and \rightleftharpoons which you might use for this purpose are too short and the arrow heads are not like the "standard" ones you will find in books or journals on chemistry. The macro chemarrow.sty in conjunction with the font arrow.mf is supposed to make the typesetting of chemical reaction schemes in LaTeX easier and especially nicer looking. 2) Dateien arrow.mf MetaFont source code of the arrow font arrow.tfm .tfm Datei of arrow for the use with TeX chemarrow.sty macro for the typesetting of arrows in chemical reaction schemes Readme.txt English Readme testchem.tex test file for chemarrow.sty and arrow.mf Liesmich.txt German Readme Type 1/arrow Mac.sit.hqx type 1 version of arrow for Macintosh Type 1/arrow PC.zip type 1 version of arrow for PC/Unix Type 1/arrow.mp MetaPost source code of arrow There is no need to copy the FontLab file arrow.vfb included in both of the type 1 archives, I just put it there in case you want to enhance my designs :-) 3) Usage The examples in the file testchem.tex should be sufficient for the understanding of how chemarrow.sty works, and there's also a short description in chemarrow.sty of all the newly defined commands. 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
