如何将Image obj转换为Bitmap obj,反之亦然

我有一个方法获取Image对象输入并返回Image对象,但我想给位图对象输入然后获取位图对象输出我的代码是这样的:

    // Image size
    int width = imageIn.getWidth();
    int height = imageIn.getHeight();
    boolean[][] mask = null;
    Paint grayMatrix[] = new Paint[256];

    // Init gray matrix
    for (int i = 0; i <= 255; i++) {
        Paint p = new Paint();
        p.setColor(Color.rgb(i, i, i));
        grayMatrix[i] = p;
    }
    int [][] luminance = new int[width][height];
    for (int y = 0; y < height ; y++) {
        for (int x = 0; x < width …
