Other packages (eg, {\tt txgreeks}, providing the option of upright or slanted Greek letters) extend the range of coverage of its macros. + +These packages contain some interesting math alphabets. The script alphabet glyphs (upper case only) seem to be identical to those in {\tt Mathematica5}, but the Fraktur font common to both packages is. as far as I can tell, distinct from the Fraktur of other major math font packages, and worthy of note. Blackboard bold comes in two different versions in {\tt txfonts} (openface and double-struck) and in yet another double-struck version in {\tt pxfonts}. The double-struck alphabets are similar in overall style to those in {\tt mathpazo} and {\tt Mathematica7}, with stems a mix of double-struck, regular weight and solid bold. + + +The original plan was to provide virtual fonts for all these alphabets, plus packages that allow them to be used in stand-alone fashion and as part of the \textsf{mathalfa} package. + +In the decade since this package was first released, some changes have been made to the original alphabets, most notably: +\begin{itemize} +\item +the Fraktur fonts have been modified so that they now match the weight of Times-like fonts rather than lighter fonts such as Computer Modern; +\item The secondary Blackboard Bold font provided with {\tt newtx}, with uppercase letters of the form $\mathbb{ABCDEXYZ}$ has been extended with full lowercase plus {\tt dotlessi} and {\tt dotlessj}, like $\mathbb{abcdexyz}$. +\end{itemize} + + +The package contains the following files: + +Virtual fonts ({\tt.tfm} and {\tt.vf}): + +\begin{tabular}{lll} +{\tt txr-cal}&Regular weight calligraphic from {\tt txfonts} and {\tt pxfonts}.\\ +{\tt txb-cal}&Bold weight calligraphic from {\tt txfonts} and {\tt pxfonts}.\\ +{\tt txr-frak}&Regular weight fraktur from {\tt txfonts} and {\tt pxfonts}.\\ +{\tt txb-frak}&Bold weight fraktur from {\tt txfonts} and {\tt pxfonts}.\\ +{\tt txr-of}&Regular weight openface from {\tt txfonts}.\\ +{\tt txb-of}&Bold weight openface from {\tt txfonts}.\\ +{\tt txr-ds}&Regular weight double-struck from {\tt txfonts}.\\ +{\tt pxr-ds}&Regular weight double-struck from {\tt pxfonts}.\\ +{\tt pxb-ds}&Bold weight double-struck from {\tt pxfonts}. +\end{tabular} + +Font definition ({\tt.fd}) files: + +\begin{tabular}{lll} +{\tt utx-cal.fd}&Regular and bold weights, calligraphic.\\ +{\tt ot1tx-frak.fd}&Regular and bold weights, fraktur.\\ +{\tt utx-of.fd}&Regular and bold weights, openface.\\ +{\tt ot1tx-ds.fd}&Regular weight double-struck from {\tt txfonts}.\\ +{\tt upx-ds.fd}&Regular and bold weights, double-struck from {\tt pxfonts}. +\end{tabular} + +Style files: + +\begin{tabular}{lll} +{\tt pxtx-cal.sty}&Load regular and bold weights, calligraphic.\\ +{\tt pxtx-frak.sty}&Load regular and bold weights, fraktur.\\ +{\tt tx-of.sty}&Load regular and bold weights, openface.\\ +{\tt tx-ds.sty}&Load regular weight double-struck from {\tt txfonts}.\\ +{\tt px-ds.sty}&Load regular and bold weights, double-struck from {\tt pxfonts}.\\ +\end{tabular} +(Only {\tt pxtx-frak.sty} and {\tt tx-ds.sty} have been modified since the the original versions.) +When loaded following loading other math sty files, these will replace one of the math alphabets. For example, {\tt tx-ds.sty} will redefine \verb|\mathbb| and its associated special characters, like \verb|\bbdotlessi|, to use the double-struck glyphs from {\tt newtx}. + +\section{The interesting font files} +The files ({\tt.afm} and {\tt.pfb}) with glyphs of interest are: +\begin{verbatim} +txmiaX, txbmiaX---Fraktur (UC, lc) and Double-Struck (regular weight only) +txsy, txbsy---Calligraphic (UC) +txsyb, txbsyb---Openface (UC) +pxsyb, pxbsyb---Double-Struck (UC) +\end{verbatim} + + This package depends on {\tt txfonts} and {\tt pxfonts}. It will not function unless the map files {\tt txfonts.map} and {\tt pxfonts.map} are enabled. This is the default in \TeX\ Live installations. + + +On the other hand, the metrics for the math alphabets in this collection have been adjusted and do not have the problems of the originals. This is a matter of personal taste, and may not suit yours. Sorry---there is no way to allow simple user-configured settings for these parameters. + +The easiest way to use the fonts in this package is {\tt mathalpha}, \textsc{aka} {\tt mathalfa}, the latest version of which builds in support for these alphabets. For font samples, see the documentation for that package. + +\end{document} + |
