java - Java 交叉影线纹理

Question

知道如何在 Java 中重新创建交叉散列纹理吗？下面的 C# 代码显示了如何为 .NET 框架完成此操作。Java 代码片段很接近，但我无法将线条正确旋转 45 度。

C＃

HatchBrush crossHatch =
        new HatchBrush(HatchStyle.Cross, somecolor, somecolor);

BufferedImage bufferedImage =
        new BufferedImage(5, 5, BufferedImage.TYPE_INT_ARGB);

Graphics2D g2 = bufferedImage.createGraphics();

g2.setColor(Color.BLUE);
g2.fillRect(0, 0, 5, 5);
g2.setColor(pinColor);
g2.fillOval(0, 0, 5, 5);

// paint with the texturing brush
Rectangle2D rect = new Rectangle2D.Double(0, 0, 5, 5);
g2d.setPaint(new TexturePaint(bufferedImage, rect));
g2d.fill(shape);

提前致谢。

这是一个应该以 5 像素间隔交叉的阴影：

BufferedImage bufferedImage =
        new BufferedImage(5, 5, BufferedImage.TYPE_INT_ARGB);

Graphics2D g2 = bufferedImage.createGraphics();
g2.setColor(backColor);
g2.fillRect(0, 0, 5, 5);
g2.setColor(stripeColor);
g2.drawLine(0, 0, 5, 5); // \
g2.drawLine(0, 5, 5, 0); // /

// paint with the texturing brush
Rectangle2D rect = new Rectangle2D.Double(0, 0, 5, 5);
g2d.setPaint(new TexturePaint(bufferedImage, rect));
g2d.fill(shape);
