4.6 Creating Font Derivations

Using the Font.deriveFont methods, you can create a new Font object with different attributes from an existing Font object. Often, a transform is applied to the existing Font to create a new derived Font. To do this, you:

Create a Font object.,

Create the AffineTransform you want to apply to the Font.

Call Font.deriveFont, passing in the AffineTransform.

In this way, you could easily create a Font in a custom size or a skewed version of an existing Font.
In the following code excerpt, an AffineTransform is applied to create a skewed version of the font Helvetica. The new derived font is then used to render a string.

	
	// Create a transformation for the font.
	AffineTransform fontAT = new AffineTransform();
	fontAT.setToShear(-1.2, 0.0);
	// Create a Font Object.
	Font theFont = new Font("Helvetica", Font.PLAIN, 1);
	// Derive a new font using the shear transform
	theDerivedFont = theFont.deriveFont(fontAT);
	// Add the derived font to the Graphics2D context
	g2.setFont(theDerivedFont);
	// Render a string using the derived font
	g2.drawString("Java", 0.0f, 0.0f);
