Drawing functions

Point paper is created and modified with appropriate drawing functions. The options concern: the type of figure empty or full; the way it is drawn: from the corners or from the center; and the possible sequence of figures. For some functions you can set values and the program will draw the figure exactly.

Pattern Management

The management of patterns is flexible not only because patterns can be created in different ways, but especially because the colors of which the pattern is composed can be matched with different colors in the point paper.
If some colors not needed, they can be declared transparent.
