如何使用颜色色调绘制BufferedImage [英] How to draw a BufferedImage with a color tint

问题描述

我正在尝试使用不同的颜色色调将 BufferedImage 绘制到我的 Canvas ，但不能找到任何真正有用的例子。

I'm trying to draw a BufferedImage to my Canvas with a varying color tint, but can't find any real working examples.

我不想生成新的有色 BufferedImage ，但是反复绘制一个 BufferedImage 实时显示我的GUI，具有不同的颜色色调，具体取决于各种条件。

使用淡色调<$ c $绘制的图像c> 0xFF0000 将绘制为仅红色图像，而 0xFFFFFF 的色调不会影响图像。

I don't want to generate a new tinted BufferedImage, but repeatedly draw a BufferedImage to my GUI in real time with varying color tints, depending on various conditions.
An image drawn with a tint color of 0xFF0000 will be drawn as a red-only image, while a tint color of 0xFFFFFF won't affect the image.

如何使用我的控件的 Graphics2D 实例来完成这样的事情？

How would I accomplish such a thing using the Graphics2D instance of my control?

提前致谢。
