Examples of java.awt.font.TextLayout.draw()

java.awt.font.TextLayout.draw()
Renders this TextLayout at the specified location in the specified {@link java.awt.Graphics2D Graphics2D} context.The origin of the layout is placed at x, y. Rendering may touch any point within getBounds() of this position. This leaves the g2 unchanged. Text is rendered along the baseline path. @param g2 the Graphics2D context into which to renderthe layout @param x the X coordinate of the origin of this TextLayout @param y the Y coordinate of the origin of this TextLayout @see #getBounds()

            TextLayout layout = new TextLayout(text, font, context);
            Rectangle2D bounds = layout.getBounds();
            g2.setColor(foreGround);
            float textX = (float) (width - bounds.getWidth()) / 2;
            y = (float) (y + layout.getLeading() + 2 * layout.getAscent());
            layout.draw(g2, textX, (float) y);
        }
        return y;
