java - 尝试将 BufferedImage 转换为 int 数组时出错

Question

我正在尝试将 BufferedImage 转换为整数数组，但收到以下错误:“java.awt.image.DataBufferByte 无法转换为 java.awt.image.DataBufferInt"

这是我的代码:

public class Test {
  public static void main (String []  args) { 
    BufferedImage img = null;
    try {
      img = ImageIO.read(new File("G.bmp"));
    } catch (IOException e) { }

    int[] imgarray = ((DataBufferInt)img.getRaster().getDataBuffer()).getData();
  }
}

Answer 1

试试这个:

byte[] imgarray = ((DataBufferByte)img.getRaster().getDataBuffer()).getData();
