Member variable XbpFont():nominalPointSize Foundation

The instance variable :nominalPointSize contains a numeric value indicating the average type size of the font in points (1 point = 1/72 inch). When the method :create() is called, the font object attempts to select a font of the size specified that most closely matches the properties specified in the font object's other instance variables. After the method :create() is executed, the instance variable :nominalPointSize contains a numeric value indicating the average type size of the font selected.

The font height is also affected by the :height property which can be used to specify the character height in arbitrary units. :height normally has precedence over the :nominalPointSize property. Therefore, if a point size is defined via :nominalPointSizebefore :create() is executed, the instance variable :heightmust be set to 0. Furthermore, in order to prevent distortion of the characters in the font selected, :width should also be set to 0. This causes the font to be created using the default character width for the point size specified.
