The font size taken in parameter is not the size in point (1 point = 1/72 inch) but the font's height in pixel.
Therefore you should do a conversion to have the correct font size if you want to modify a document destined to print.
For example, if your document's resolution is 300ppi, you should add a 25/6 multiplying factor to your fontsize in order to have a correct behaviour of the font.
