如何改变buffereimage的颜色#000000格式

Question

使用BufferedImage创建一张图片，颜色为深灰色:

BufferedImage image = new BufferedImage(width, height, BufferedImage.TYPE_INT_ARGB_PRE);
Graphics2D graphics = image.createGraphics();
Color darkGray = new Color(44, 47, 48);
graphics.setColor(darkGray);
graphics.fill(new RoundRectangle2D.Float(0, 0, image.getWidth(), image.getHeight(), ROUND_OF_CORNERS, ROUND_OF_CORNERS));

我想通过使用另一种颜色表示格式来改变图像的颜色，例如:#2B2B2B(而不是RGB格式:44,47,48)

Answer 1

你可以像这样解码一个十六进制值:

Color myColor = Color.decode("#2B2B2B");
