setFont

public void setFont(Font font)

This method sets the current font. However, it does not write it to the file. When drawString() wants to show text, it has to call writeFont() first, which will actually write the current font to the document. Thus we avoid embedding unused fonts (e.g. the Dialog font which is set by java for whatsoever reason

Overrides:

setFont in class AbstractVectorGraphics

Parameters:

font - to be set
