本文整理了Java中java.awt.image.BufferedImage.getType()方法的一些代码示例，展示了BufferedImage.getType()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.getType()方法的具体详情如下：
包路径：java.awt.image.BufferedImage
类名称：BufferedImage
方法名：getType

BufferedImage.getType介绍

[英]Returns the image type. If it is not one of the known types, TYPE_CUSTOM is returned.
[中]返回图像类型。如果不是已知类型之一，则返回类型\自定义。

private static BufferedImage scaleDown(BufferedImage sourceImage, int targetWidth, int targetHeight) {
  int sourceWidth  = sourceImage.getWidth();
  int sourceHeight = sourceImage.getHeight();
  BufferedImage targetImage = new BufferedImage(targetWidth, targetHeight, sourceImage.getType());
  Graphics2D g = targetImage.createGraphics();
