Detailed Description

Class to build an items legend.

This legend associates a string (this is the values of the legend) to a box or/and a line or/and a marker. All the sizes cannot be controlled by the application and depend on the dimensions of the legend. The font size F of strings is calculated as function of the rectangle delimiting the legend. The size of the markers is equal to F. The height of the boxes is equal to 1.5 * F, and the width of the lines and of the boxes is equal to 1.5 * F * boxRatio.
