[置顶] android获取图象点阵数组的方法

int []testbufall = new int[WIDTH*HEIGHT]; int total =WIDTH*HEIGHT;  int imgWidth; int imgHeight;  float widthscale,heightscale; Bitmap   image = BitmapFactory.decodeFile(strFilePath); imgWidth = image.getWidth(); imgHeight = image.getHeight(); //计算缩放比例 Matrix matrix=new Matrix(); widthscale = (float)480/imgWidth; heightscale=(float)272/imgHeight;       matrix.postScale(widthscale,heightscale); Bitmap bmp=Bitmap.createBitmap(image,0,0,imgWidth,imgHeight,matrix,false); bmp.getPixels(testbufall,0,WIDTH,0,0,WIDTH,HEIGHT);   testbufall保存的就是RGB8888的点阵数据了，每个int保存一个像素的数据
