Source Link

Document

Constructs a FontRenderContext object from an optional AffineTransform and two Object values that determine if the newly constructed object has anti-aliasing or fractional metrics.

Usage

From source file:Main.java

public static boolean isVectorFont(Font font) {
    GlyphVector gv = font.createGlyphVector(new FontRenderContext(null, true, false), "Test");
    Shape fontShape = gv.getOutline();
    Rectangle2D bounds = fontShape.getBounds2D();
    return !(bounds.getWidth() == 0 && bounds.getHeight() == 0);
