How to draw a BufferedImage with a color tint

问题

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

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.

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

Thanks in advance.

Maybe ColorTintFilter from Filthy Rich Clients book can help you. The relevant sample chapter from the book is available here.

Here is a code snippet that uses the filter:

BufferedImage image = ...;
BufferedImageOp imageFilter = new ColorTintFilter(Color.RED, 1.0f);
image = imageFilter.filter(image, null);
