是否存在类似于java getData（）.getPixels（）的android方法？

Question

    private double[] getImageData(String imageFileName) throws FaceRecError {
    BufferedImage bi = null;
    double[] inputFace = null;
    try{
        bi = ImageIO.read(new File(imageFileName));
    }catch(IOException ioe){
        throw new FaceRecError(ioe.getMessage());
    }
    if (bi != null){
    int imageWidth = bi.getWidth();
    int imageHeight = bi.getHeight();
    inputFace = new double[imageWidth * imageHeight];
    bi.getData().getPixels(0, 0, imageWidth, imageHeight,inputFace);
    }
    return inputFace;
}   

Answer 1

此代码用于获取Android中位图中所有像素的颜色。返回颜色数组

    Bitmap bitmap=BitmapFactory.decodeFile("file path");
    int height=bitmap.getHeight();
    int width=bitmap.getWidth();
    int[] pixel=new int[height*width];
    bitmap.getPixels(pixel, 0, width, 0, width, width, height);

所以你的颜色将保存在像素阵列中。getPixels()有许多参数可用于自定义所需的像素颜色

已更新用于将整数数组强制转换为double

public  double[] getDoubleNumbers(int[] numbers) 
//changed double to double[]
{double[] newNumbers = new double[numbers.length]; //changed 99 to numbers.length
for (int index = 0; index < numbers.length; index++)
newNumbers[index] = (double)numbers[index];

return newNumbers;
}
}
