% 'Shading.sty'
%
% Art Mulder ( [email protected] ) 28-Sept-1992
% - Changed name of "linewidth" variable to "outlineboxwidth".
% That variable name conflicted with another variable of the same
% name in "latex.tex" when doing miniparagraphs.
% - Wrote accompanying document ``shading.tex'', brief instructions
% in the use of this style file, together with several examples.
%
% M.A.R. ( [email protected] ) 22 Jan 92
% - Modified to work as a LaTeX style:
% - added setting the grayscale as an optional argument.
% - allowed multiple paragraphs in the \parashade command
%
% Leo ?? ( [email protected] )
% - Wrote the original TeX code, based upon some ideas
% from Je'ro^me Maillot ( [email protected] ).
%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%
% USAGE: \textshade[grayscale]{corneroption}{text to be shaded}
% \parashade[grayscale]{corneroption}{paragraph(s) to be shaded}
% where
% grayscale is a number from 0 to 1, the higher the number the
% lighter the shading, if missing it is set to 0.95
% corneroption is either sharpcorners or roundcorners
%
% LIMITATIONS: --can not break the shaded text across lines (\textshade) or
% across pages (both)
% --can not specify the line width of the surrounding box or
% the amount of space between the surrounding
% box and the text to be shaded as arguments
% (Actually you can, see the use of "\gdef" in the example)
% --modifying the xgrayspace and ygrayspace in the argument
% will only affect the space added to the right and
% bottom of the box, respectively
%
% EXAMPLES:
% This is a test of a\ \textshade[1]{roundcorners}{shaded box} routine.
% With a grayscale of 1, we essentially get no shading, and just a box.
%
% This is another test of a\ \textshade{sharpcorners}{shaded box} routine.
% The default shading of .95 is used here.
%
% \parashade[.995]{roundcorners}{\gdef\outlineboxwidth{.5}%
% This is one very long line which I expect will be broken over one or more
% lines. The idea is to have this paragraph enclosed in a shaded box. I'll
% just keep on typing until I can be sure that there are more than two lines
% in this paragraph. I expect that this should be well and truely sufficient
% to test this macro.
% } %This shows an example of changing the outlineboxwidth used, without
% %changing the style
%
% The field equations of General Relativity are\ %
%%
% \textshade{roundcorners}{\hbox{$G_{\mu\nu} = kT_{\mu\nu}$}}
%
% They can also be written as
%
% \parashade{sharpcorners}{$$R_{\mu\nu}-{1\over2}g_{\mu\nu}R = kT_{\mu\nu}$$}
