%% This is file `baposter.cls'
%%
%% A relatively comfortable latex class to produce posters with a grid based
%% layout. It comes with a number of combinable styles and is (maybe only for
%% the writer) easy to extend, as all the graphics is based on pgf.
%%
%% It is meant to be used with pdftex, but might also work with pslatex if you
%% are not interested in things like transparency.

%% 29. September 2011: 
%%     - Finally fixed confusion with paper size handling and landscape. This required seperate handling of papersizes 
%%       known to the geometry package and other packages.
%% 26. September 2011:
%%     - Reverted drawing of faded borders to manual method, as the current result does not work with evince, 
%%       and produced spurious colored boxes with okular and acroread.
%%     - Added one more example due to popular request
%% 16. September 2011:
%%     - Removed nag package, such that it compiles on older systems
%%     - Added more examples
%% 15. September 2011:
%%     - Merged fork by (rk) back into mainline, essentially taking over all the great improvements that Reinhold Kainhofer coded.
%%       We call this version 2, as it breaks the interface in some small points. Essentially watch out for this:
%%       - no/yes keys are now false/true
%%       - the shade-lr etc. keys have the hypen removed, and are now called shadelr etc.
%      - Added more examples, which are all adapted to work with the current version
%% 27. August 2011 (rk):
%%     - Completely factored out all drawing commands to handler functions, assigned via choice keys
%%     - Added cornerradius, boxheaderheight, boxpadding options
%%     - Added missing roundedright
%% 26. August 2011 (rk):
%%     - Turned headerbox cmd into posterbox environment (allows verbatim)
%%     - pass several options to packages
%%     - added debug cls option to reduce default output
%%     - rewrote several loops and ifthenelse
%%     - Use boolean and choice keys for all options
%%     - Changed all choice options to set a global function to
%%       \baposter@OPTION@OPTIONVALUE, which are a functions that execute the
%%       option's setting (drawing routine, color setting for tikz, etc.)
%%     - Add a5paper
%% 07. April 2011: Fixed paper size handling
%%     - Fixed Paper Size handling, you can now specify all page sizes using paperwidth=, paperheight= class options.
%%     - Added rudimentary documentation of the available keys.
%% 11. December 2010: Fixed "Empty Second Page" bug
%%     - A second empty page was introduced when a document ended with
%%           \end{poster}
%%         \end{document}
%%       This was fixed thanks to a suggestion by Martin Aulbach
%%     - Added
%%         \thispagestyle{empty}
%%       to suppress page numbers, which became visible when the margins are large.
%%       The underlying problem of page-size handling has not yet been solved.
%% 30. September 2010: Border Bugfixes
%%     - Correct background color with textborder=rounded-small, Thanks to Ke Chen for the bugreport and patch
%%     - Correctly draw rectangular text boxes, Thanks to abenkst for the bugreport and fix
%% 10. June 2010: Added option to set the number of columns
%%     - added a class option to set the number of columns
%%         - columns=5: sets the number of columns to 5, possible values are 1..6, default is 3 in portrait and 4 in landscape format
%% 29. April 2009: Incorporated Patches by Arne Henningsen
%%     - added some class options
%%        - a4shrink: shrink the paper to A4 size (for printing drafts or handouts)
%%        - movebody=Xpt: move the text/poster body Xpt to the right
%%                    (or to the left if Xpt is negative),
%%                    e.g. for manually centering the poster on the page
%%        - showframe: use the "showframe" option of the "geometry" package
%%        - a0paper (default): set paper size to A0
%%        - archE: set paper size to Arch E
%%     - setting "background" can be "none" now (otherwise the "showframe"
%%          option has no effect)
%%     - the page number has been removed (it was mostly not visible before)
%%     - the "margin=" option works now
%% 04. December 2008
%%     - Mainly an update to the landscape example
%% 14. November 2008
%%     - Actually center the title when eyecatcher is used.
%% 04. November 2008
%%     - Fixed bug with eyecatcher not working.
%% 26. June 2008
%%     - Fixed bug with plain background mode.
%% 14. June 2008
%%     - Support for portrait/landscape switching.
%%     - Some smaller bugfixes.
%% 01. June 2007
%%     - First version released.
%%
%% Use this class with pdflatex
%%
%% I have confirmed that this package works with
%%   - texlive 2007 and
%%   - miktex 2.7
%%
%% It does not seem to work with
%%   - miktex 2.2
%%   - some old versions of tetex
%%
%%
%% TODO:
%% -) Rename backgrounds back to shaded-tb shade-lr
%% -) Rename textborder back to rounded-small (consistent naming needed!)
%% -) Rename headershade back to shade-lr, shade-tb, shade-tb-inverse
%% -) Rename headershape back to small-rounded
%% -) Option value consistency (small-rounded vs. rounded-small; missing ones)
%% -) Rename \baposterHeaderSetShade, \baposterHeaderDrawText to include @ and verb
