\subsection{Object-oriented programming}

The extensive use of large XPMs by simply including them with an \texttt{\#include} directive gives rise to large executable files, besides making it harder to change the used XPMs without recompiling the project.\par

The XPM2 file format is similar to XPM, except it is stripped from all the C syntax, making it a plain text file. This file format has the main advantage of being easy to load on runtime, unlike XPM that would require extensive parsing.\par

To use the XPM2 file format, two functions \texttt{xpm\_save\_to\_xpm2} and \texttt{xpm\_load\_xpm2} were implemented; the first one to convert XPM files to XPM2 files, and the second one was used in the project to load the XPM data (as an array of C-strings) from the XPM2 file format.
