Gets the standard height of a line of text in this font.

Usage

From source file:com.celements.photo.image.GenerateThumbnail.java

private void drawWatermark(String watermark, Graphics2D g2d, int width, int height) {
    //TODO implement 'secure' watermark (i.e. check if this algorithm secure or can it be easily reversed?)
    g2d.setColor(new Color(255, 255, 150));
    AlphaComposite transprency = AlphaComposite.getInstance(AlphaComposite.SRC_OVER, 0.45f);
    g2d.setComposite(transprency);//from  w w w. j  a  v a  2  s  .co  m

    FontMetrics metrics = calcWatermarkFontSize(watermark, width, g2d);
    g2d.setFont(calcWatermarkFontSize(watermark, width, g2d).getFont());

    // rotate around image center
    double angle = (Math.sin(height / (double) width));
    g2d.rotate(-angle, width / 2.0, height / 2.0);

    g2d.drawString(watermark, (width - metrics.stringWidth(watermark)) / 2,
            ((height - metrics.getHeight()) / 2) + metrics.getAscent());

    // undo rotation for correct copyright positioning
    g2d.rotate(angle, width / 2.0, height / 2.0);
