There's no +% support and everything may change!}\fi +% } +% \author{Markus Kohm} +% \date{\filedate~\fileversion} +% \maketitle +% \begin{abstract} +% Grid setting\,---\,also known as strict in-register setting\,---\,is +% something, that should be done for a lot of documents but is not easy +% using \LaTeX{}. Package \textsf{gridset} helps to get the information +% needed for grid setting. It does not implement auto grid setting, but +% there is a command \cs{vskipnextgrid}, that moves to the next grid +% position. This may be enough under some circumstances. In other +% circumstances it may fail. So \textsf{gridset} is only one more step for +% grid setting not a complete solution. +% \end{abstract} +% \tableofcontents +% \section{User Manual} +% +% \DescribeMacro{\gridinterval}% +% This macro contains a number without unit! The number is the distance +% between two grid lines in unit `scale points' (sp). You may set it so +% another value using, e.g. +% \begin{flushleft} +% |\newlength{\|\meta{name of your length}|}|\\ +% |\setlength{\|\meta{name of your length}|}{|\meta{new length value}|}|\\ +% |\newcounter{\|\meta{name of your counter}|}|\\ +% |\setcounter{\|\meta{name of your counter}|}{\|\meta{name of your +% length}|}|\\ +% |\edef\gridinterval{\|\meta{name of your length}|}|\\ +% \end{flushleft} +% +% \DescribeMacro{\gridbase}% +% This macro contains an integer number, that represents the y-coordinate of +% the upper start of the grid. If you want to change it, just save a position +% and \cs{edef} the \cs{gridbase} to the y-pos of that position. +% +% Most time you don't need to change \cs{gridinterval} and \cs{gridposition}, +% because they are initialized to a base line grid at start of first page. +% Because of this, it doesn't matter, that changing them is not really user +% friendly. +% +% \DescribeMacro{\savepos}% +% \cs{savepos}\marg{unique name} saves informations about the current position +% to the \texttt{aux}-file. These informations are read at next \LaTeX{} run +% and may be used (see \cs{the\dots} commands below) then. The \meta{unique +% name} has to be a position name, that is unique for all saved position +% informations of the current document. +% +% \DescribeMacro{\vskipnextgrid} +% This command moves to the next grid position. To achieve this, a position +% information is saved at this and used at next \LaTeX{} run. The used name +% of the position information is \texttt{vb!\meta{number of +% skip}}. \meta{number of skip} is the number of the current +% \cs{vskipnextgrid} usage. Counter \texttt{gridcnt} is used to number the +% usage of \cs{vskipnextgrid}. +% +% \DescribeMacro{\thegridinfo} +% \cs{thegridinfo}\marg{name} outputs +% \begin{itemize} +% \item arabic page number of the named position, +% \item grid base, that was valid saving the information of the named +% position, +% \item grid interval, that was valid saving the information of the named +% position, +% \item x-coordinate of the named position, +% \item y-coordinate of the named position. +% \end{itemize} +% The coordinates and intervals are numbers without units. The unit is `scale +% points' (sp). +% +% \DescribeMacro{\theposinfo} +% \cs{theposinfo}\marg{name} outputs +% \begin{itemize} +% \item y-coordinate of the named position, +% \item grid line number (first is 0) of the next grid position, +% \item offset of the next grid position from grid base, +% \item distance to the next grid position. +% \end{itemize} +% The coordinates, offsets and distances are numbers without units. The unit +% is `scale points' (sp). +% +% \DescribeMacro{\theypos} +% \cs{theypos}\marg{name} outputs the y-coordinate of the named position. +% +% +% \StopEventually{\PrintIndex\PrintChanges} +% +% \section{Implementation} +% +% \iffalse meta-comment +%<*package> +% \fi ^^A meta-comment +% \begin{macrocode} +%<package>\ProvidesPackage{gridset}[\fileversion\space (package)] +% \end{macrocode} +% +% \begin{macro}{\gridbase} +% \begin{macro}{\gridinterval} +% These contain the grid information. \cs{gridbase} is a integer number +% representing the absolute y coordinate of the upper end of the +% grid relative to the same reference point \cs{pdfsavepos} +% uses. \cs{gridinterval} is a integer number representing the distance of +% two grid lines.
