April 8, 97 and November / December 97): +%% * With a \PstTiling macro defined (or "tiling" optional parameter +%% on \usepackage[tiling]{pst-fill}), this file run exactly as +%% the original boxfill.tex file from Timothy, version 0.94, +%% except a correction in \pst@ManualFillCycle to avoid a division by 0. +%% It's the default. +%% * With a \PstTiling macro defined (or "tiling" optional parameter +%% on \usepackage[tiling]{pst-fill}) there are several add-ons +%% and changes to do `tiling' rather than `filling' in "automatic" mode : +%% - we fix the position of the beginning of tiling, +%% - we allow normally the framing of the area as expected, using +%% the line.... parameters +%% - we define move parameters fillmovex, fillmovey and fillmove, +%% - we define fillcyclex as previous fillcycle parameter, and add the +%% fillcycley and fillcycle (both fillcyclex and fillcycley) ones +%% - we can extend the tiling area using fillloopaddx, fillloopaddy and +%% fillloopadd parameters, +%% - we can debug and see the whole tiling area without clipping using +%% PstDebug parameter, +%% - for names consistancy, we can use fillangle in place of boxfillangle +%% and fillsize in place of boxfillsize, +%% -
