本文整理了Java中java.awt.image.BufferedImage.getGraphics()方法的一些代码示例，展示了BufferedImage.getGraphics()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。BufferedImage.getGraphics()方法的具体详情如下：
包路径：java.awt.image.BufferedImage
类名称：BufferedImage
方法名：getGraphics

BufferedImage.getGraphics介绍

[英]This method returns a Graphics2D, but is here for backwards compatibility. #createGraphics() is more convenient, since it is declared to return a Graphics2D.
[中]此方法返回一个Graphics2D，但此处是为了向后兼容#createGraphics（）更方便，因为它被声明为返回一个Graphics2D。

代码示例

static Icon getColorIcon (java.awt.Color color) {
  BufferedImage image = new BufferedImage(32, 16, BufferedImage.TYPE_INT_RGB);
  java.awt.Graphics g = image.getGraphics();
  g.setColor(color);
  g.fillRect(1, 1, 30, 14);
  g.setColor(java.awt.Color.black);
  g.drawRect(0, 0, 31, 15);
  return new ImageIcon(image);
}

File path = ... // base path of the images

// load source images
BufferedImage image = ImageIO.read(new File(path, "image.png"));
BufferedImage overlay = ImageIO.read(new File(path, "overlay.png"));

// create the new image, canvas size is the max. of both image sizes
int w = Math.max(image.getWidth(), overlay.getWidth());
int h = Math.max(image.getHeight(), overlay.getHeight());
BufferedImage combined = new BufferedImage(w, h, BufferedImage.TYPE_INT_ARGB);

// paint both images, preserving the alpha channels
Graphics g = combined.getGraphics();
g.drawImage(image, 0, 0, null);
g.drawImage(overlay, 0, 0, null);

// Save as new image
ImageIO.write(combined, "PNG", new File(path, "combined.png"));
