Latex/TikZ chessboard pattern generator

edit

I've always felt that generating a suitable chessboard target PDF file for the calibration task at hand is difficult. Therefore, I've created a simple Latex/TikZ based generator for plain checkerboard patterns

https://github.com/cheind/chessboard-...

in the hope this is useful for other people as well. The generator allows tweaking the usual chessboard properties and metric dimensions, adds CYMK color settings, and optionally adds chessboard meta info as text to the board. The template will be shortly available through Overleaf as well, which will save people from having to install Latex.

Other patterns are currently not supported, but could be easily added in similar manner in the future.
