Nested \multips doesn't work. +% PATCH: Input this file. +% +% 6. \psgrid sometimes gets the size wrong by 1 unit. +% PATCH: Input this file. +% +% 7. \begin{overlaybox} ... \end{overlaybox} cannot be used instead +% of \overlaybox ... \endoverlaybox. +% PATCH: Input this file. +% +% 8. Overlays don't interact properly with rotation. +% PATCH: Input this file. +% +% 9. Overlays don't work properly with nodes. Specifically, they only work +% when the nodes and node connections and labels are all on the same +% overlay. +% PATCH: Input this file, and include the command \AltOverlayMode +% before the overlay in which you want to use nodes (before the whole +% overlay box or slide, or in the beginning of the document). +% Warning: Normally, overlay material is made invisible by translating +% it off the page. With \AltOverlayMode, it is done by setting a small +% clip path somewhere off the page. The material is made visible again +% by issuing "initclip", which resets the clipping path completely. +% This makes it incompatible with any other clipping tricks. +% +% 10. SpecialCoor and the : version of nrot do not work when ;!|: +% do not have \catcode 12 (e.g., with french.sty). +% +% PATCH: Input this file, and read the following: +% +% FAQ: What non-standard category codes and active characters are +% compatible with PSTricks? +% +% Using non-standard category codes can confuse PSTricks in many ways. +% What follows is not comprehensive. +% +% Characters ()[],*=- +% These must have category code 3, 7, 8, 11 or 12. +% The category code must be set BEFORE inputting the PSTricks files. +% +% Characters <>|;!: +% Same as above, but category code 13 (``active'') is also OK, in +% which case the code must be 12 when the PSTricks files are input. +% +% Characters \{}@#$%^&_ +% These should have their usual category codes when PSTricks files +% are input, but then they can be set arbitrarily. +% +% Characters +"'.?/~` +% No restrictions, but generally these should have category code 12 +% when the PSTricks files are input. +% +% 11. Gradient fill style doesn't work the gradmidpoint=0 or gradmidpoint=1. +% WORKAROUND: Until the next release, set gradmidpoint +% close to, but not too close to or equal to, 0 or 1. +% +% 12. If using \pscharpath with protected fonts, the dashed and dotted +% linestyles, setting shadow=true, and \pstextpath produce an +% invalidaccess error. +% WORKAROUND: Until the next release, do not use those features with +% \pscharpath and protected fonts. In the next release, the dashed +% and dotted line styles will work, and shadow=true and \pstextpath +% will neither work nor produce errors with protected fonts. +% +% 13. \scalebox and \scaleboxto do not work properly with negative scaling. +% +% 14. With \psplot, setting labels=y or ticks=y does not suppress labels +% or ticks on the x-axis. +% PATCH: Get version 0.93a-patched of pst-plot.tex, distributed +% which is part of the 0.93a distribution starting March 30, 1994. +% +% 15. When lines are very short, linestyle=dash may cause an error. +% PATCH: Input this file. +% +% 16. \clipbox does not work. +% PATCH: Input this file. +% +% 17. Various nodes are missing \leavevmode, which can cause irregularities +% if they occur at the beginning of a paragraph. +% WORKAROUND: Put \leavevmode before the offending node command. +% E.g., \leavevmode\rnode{foo} +% +% 18. The Textures entry in the configuration file has several problems. +% WORKAROUND: Contact tvz@Princeton.EDU to get a new pstricks.con. +% +% 19. There are two problems with using PSTricks without a header file: +% 1. pst-make.tex gives an error. +% 2. You get a PostScript error. +% WORKAROUND: +% 1. At the end of pst-make.tex, change to line +% \MakeInputHpst-coil.doc}{pst-coil.tex} +% to +% \MakeInput{pst-coil.doc}{pst-coil.tex} +% (The `H' become `{'). +% 2. In pstricks.doc (before running pst-make.tex) or in +% pstricks.tex (after running pst-make.tex), add the line +% /T /translate load def +% between the lines +% /CP /currentpoint load def +% /ED { exch def } bind def +% +% 20. Mixed coordinates do not work with \SpecialCorr +% PATCH: Input this file. +% +% 21. Axis labels in \psplot use a hyphen instead of a minus sign. +% PATCH: Get version 0.93a-patched of pst-plot.tex, +% which is part of the 0.93a distribution starting March 30, 1994. +% +% 22. For certain plotstyle's the \fileplot command does not work. +% PATCH: Get version 0.93a-patched of pst-plot.tex, +% which is part of the 0.93a distribution starting March 30, 1994. +% +% 23. \scale does not work in \pscustom. +% PATCH: Input this file. + +\edef\TheAtCode{\the\catcode`\@} +\catcode`\@=11 + +% 1. +\def\pst@divide#1#2#3{% + \pst@@divide{#1}{#2}% + \pst@dimtonum\pst@dimg{#3}}
