在JfreeChart中绘制模糊的阴影? [英] Drawing blured shadow in JfreeChart?

问题描述

这是帖子标题中的问题，但无论如何:

That's is question is in the title of this post, but anyway:

我使用JFreeChart在我的应用程序中创建图表.要求之一是柔和的模糊阴影而不是实心阴影，默认情况下会显示.

I use the JFreeChart to create chart in my app. And one of requirement is a soft blured shadow instead solid, which is presented by default.

我知道我可以使用

setShadowPaint(Paint paint);

但是这种方式意味着创建模糊的图像并将其添加到我的报告中.是否有建立案例以达到所需的效果?

but this way implies the creating blured image and adding it to the my report. Is there built case to achive needed effect ?

谢谢大家.

推荐答案

没有内置的内容，但是您可以使用ConvolveOp来模糊图像.请参阅此处中引用的文章作为示例.您应该能够在BufferedImage中撰写合适的图像并将其作为

There's nothing built-in, but you can use a ConvolveOp to blur an image; see the articles cited here for examples. You should be able to compose a suitable image in a BufferedImage and add it to the chart as an annotation.
