Method

voidpaintBorderDebugInfo(final Graphics g, final JComponent c, final Color color)
Paints border debug information. 
final Insets margin = c.getInsets();
g.setColor(color);
g.drawRect(0, 0, c.getWidth() - 1, c.getHeight() - 1);
g.drawRect(margin.left, margin.top, c.getWidth() - margin.left - margin.right - 1,
        c.getHeight() - margin.top - margin.bottom - 1);
voidpaintBorderGlow(final Graphics2D g2, final Shape shape, final int glowWidth)
paint Border Glow 
int gw = glowWidth * 2;
for (int i = gw; i >= 2; i -= 2) {
    float pct = (float) (gw - i) / (gw - 1);
    Color mixHi = getMixedColor(clrGlowInnerHi, pct, clrGlowOuterHi, 1.0f - pct);
    Color mixLo = getMixedColor(clrGlowInnerLo, pct, clrGlowOuterLo, 1.0f - pct);
    g2.setPaint(new GradientPaint(0.0f, 40 * 0.25f, mixHi, 0.0f, 40, mixLo));
    g2.setColor(Color.WHITE);
    g2.setComposite(AlphaComposite.getInstance(AlphaComposite.SRC_ATOP, pct));
...
voidpaintBorderGlow(Graphics2D g2, int glowWidth, Shape clipShape, Color glowOuterHigh, Color glowOuterLow)
Paints border glow over the given clipShape with the given glow high and low colors and the given glowWidth. 
int gw = glowWidth * 2;
for (int i = gw; i >= 2; i -= 2) {
    float pct = (float) (gw - i) / (gw - 1);
    Color mixHi = getMixedColor(glowOuterHigh, pct, new Color(255, 255, 255, 200), 1.0f - pct);
    Color mixLo = getMixedColor(glowOuterLow, pct, new Color(255, 255, 255, 200), 1.0f - pct);
    g2.setPaint(new GradientPaint(0, clipShape.getBounds().height * 0.25f, mixHi, 0,
            clipShape.getBounds().height, mixLo));

paint Sequence Matrix 
Paint p = g2.getPaint();
Rectangle2D tile = (Rectangle2D) rect.clone();
int h = sequence.length() + 2;
int w = sequence.length() + 2;
Point point = new Point();
