Returns a font object that has the correct height to draw the specified text in the specified rectangle using no minimal font height.

Parameters:

rectangle - the rectangle to fit the text into

scaleFactor - the factor by which the font height should be scaled (If 1.0 is provided here, the text will will the width or the height of the rectangle completely. Note that due to possible rounding imprecision a value below 1.0 is recommended so that the text fits completely into the rectangle.)

text - the text to be drawn

fontName - the name of the font to be used

fontStyle - the style of the font to be used

Returns:

the new font object
