将 RGB 整数器转换为位图
原标题:Convert Array of RGB Integers to Bitmap

使用以下代码就能获得位图图像:

BufferedImage img = ImageIO.read(new File(bitmapURL));
int[] pixels = img.getRGB(0, 0, img.getWidth(), img.getHeight(), null, 0, img.getWidth());

执行此代码部分后, 我们有一个数组, 包含 4 字节的 Alpha、 Red、 Green 和 Blue < / code > 等任何像素的颜色 。 因此, 我要知道, 如何将像 < code> int () myPixel; 这样的数组转换为 Bitmap? 是否有人能帮助我达到此目标?

提前感谢:)

最佳回答

您可以直接使用此功能 :

image.setRGB(0, 0, width, height, pixels, 0, width);

BufferedImage im = new BufferedImage(width, height);

for (int i = 0; i < width; i++) {
  for (int j = 0; j < height; j++) {
    im.setRGB(...);
  }
}
