Java 交叉剖面线纹理

有人知道如何在 Java 中重新创建交叉哈希纹理吗？下面的 C# 代码展示了如何为 .NET 框架完成此任务。 Java 片段很接近，但我无法正确地将线旋转 45 度。

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

Java

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。

Any know how to recreate a cross hashing texture in Java? The C# code belows shows how to accomplish this for the .NET framework. The Java snippet is close, but I've been unable to correctly rotate the lines by 45 degrees.

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

Java

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);

Thanks in advance.

下面是应以 5 像素间隔绘制交叉影线的一个：

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);

Here's one that should cross-hatch at 5-pixel intervals:

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);
