Dinamic window pattern card

Information about pattern cards can be gathered throught file. Pattern cards go in pairs. Each of them carry information about constraints the user has to respect in a particular position of its board, a name and a natural positive number, also called as difficulty, that resemble a number of favours a player should be given in a multiplayer game.

This is how a pattern card should look like in a file

We decided to use a simple encoding to represent a pattern card

<name>
<number of favour> <width> <height> <costraint #1,...,constraint#width*height>

Every constraint would be represented by a pair of characters. The first must be a number, between 1 and 6, and the second should identify the colour {W=> WHITE, G=> Green, Y=>Yellow, R=> Red, V => Violet, B=>Blue}.

An example of valid pattern card file follows
