Constructor Detail

FontSizer

public FontSizer(FontSizer source)

Create a FontSizer with the same settings as the source.

Parameters:

source -

FontSizer

public FontSizer(java.awt.Font font,
                 float baseScale,

                 int maxPointSize)

Parameters:

font - the font to use as the base font.

baseScale - the scale where the base font is shown at its natural size.

multiplier - to use against the ratio of base scale:current scale.

minPointSize - the minimum point size to use for the scaled font.

maxPointSize - the maximum point size to use for the scaled font.
