如何在Java中创建这样的边框？

我一直试图复制这个边界几个小时没有成功：

有关如何做到这一点的任何想法？

Answer 1

这是来自SwingX的Borders（一些旧版本），但我现在找不到这个旧版本的存储库

通过使用此图像（cuold用un_belivable色彩着色，并需要另一个类Painter和???）

private static class RoundedBorder implements Border { private static BufferedImage img; static { try { img = ImageIO.read(RoundedBorder.class.getResource("resources/border.png")); } catch (Exception e) { } } private static final Insets SPACE_INSETS = new Insets(5, 5, 5, 5); private static final Insets INSETS = new Insets(SPACE_INSETS.top + 10, SPACE_INSETS.left + 10, SPACE_INSETS.bottom + 10, SPACE_INSETS.right + 10); @Override public Insets getBorderInsets(Component c) { return INSETS; } @Override public boolean isBorderOpaque() { return false; } @Override public void paintBorder(Component c, Graphics g, int x, int y, int width, int height) { ((Graphics2D) g).setRenderingHint(RenderingHints.KEY_TEXT_ANTIALIASING, RenderingHints.VALUE_TEXT_ANTIALIAS_ON); Rectangle b = new Rectangle(x + SPACE_INSETS.left, y + SPACE_INSETS.top, width - (SPACE_INSETS.left + SPACE_INSETS.right + 1), height - (SPACE_INSETS.top + SPACE_INSETS.bottom + 1));//top g.drawImage(img, bx, by, bx + 10, by + 10, 0, 0, 10, 10, null); g.drawImage(img, bx + 10, by, bx + b.width - 10, by + 10, 11, 0, 12, 10, null); g.drawImage(img, bx + b.width - 10, by, bx + b.width, by + 10, 22, 0, 32, 10, null);// bottom g.drawImage(img, bx, by + b.height - 10, bx + 10, by + b.height, 0, 22, 10, 32, null); g.drawImage(img, bx + 10, by + b.height - 10, bx + b.width - 10, by + b.height, 11, 22, 12, 32, null); g.drawImage(img, bx + b.width - 10, by + b.height - 10, bx + b.width, by + b.height, 22, 22, 32, 32, null);// left g.drawImage(img, bx, by + 10, bx + 10, by + b.height - 10, 0, 11, 10, 12, null);// right g.drawImage(img, bx + b.width - 10, by + 10, bx + b.width, by + b.height - 10, 22, 11, 32, 12, null);// fill g.drawImage(img, bx + 10, by + 10, bx + b.width - 10, by + b.height - 10, 15, 15, 16, 16, null); } }
