学习Graphics中遇到位图(Bitmap)中getPixels()方法，对该方法的用法大体理解，但对其中的stride参数却不明白具体的用法以及用意，现记述过程如下： getPixels()...Android英文SDK中有关getPixels()方法的介绍如下： public void getPixels (int[] pixels, int offset, int stride, int...看完英文文档仍然不甚明白，于是去搜了下中文Android文档相应内容， getPixels() public void getPixels (int[] pixels, int offset, int...然后去StackOverFlow去搜了搜"getPixels() stride"关键字，查找到如下信息： 1 In most cases the stride is the same as the...()方法介绍 2 Android中文文档getPixels()方法介绍 3 StackOverflow中关于getPixels()问答． 4 Using the LockBits method to

getPixels : 从指定图片中获取所有点的像素数组。 setPixels : 对指定图片设置所有点的像素数组。...0; int newR = 0; int newG = 0; int newB = 0; int[] pixels = new int[width * height]; bmp.getPixels...int delta = 24; // 值越小图片会越亮，越大则越暗 int idx = 0; int[] pixels = new int[width * height]; bmp.getPixels...int delta = 24; // 值越小图片会越亮，越大则越暗 int idx = 0; int[] pixels = new int[width * height]; bmp.getPixels...newPixels = new int[width * height]; int color; int pixelsR, pixelsG, pixelsB, pixelsA; bmp.getPixels
，下面我们以从Bitmap中获取NV21数据为例进行说明 从Bitmap中获取RGB数据，Android SDK提供了两种方式供我们使用 第一种是getPixels接口： public void getPixels...-38 * r - 74 * g + 112 * b + 128) >> 8) + 128; v = ((112 * r - 94 * g -18 * b + 128) >> 8) + 128; 使用getPixels...bitmap.getHeight(); int size = w * h; int[] pixels = new int[size]; bitmap.getPixels
在安卓开发中要获取一个图片的每一个像素值其实很简单： //按照参数范围获取像素数组 bitmap.getPixels(...)； //或者获取单个位置像素 bitmap.getPixel(x,y);...//获取位图的高 int[][] datas = new int[width][height]; //通过位图的大小创建像素点数组 //也可以使用getPixels...方法来获取像素数组 //bitmap.getPixels(datas, 0, width, 0, 0, width, height); int alpha = 0xFF...<< 24; bitmap.getPixels(); for (int i = 0; i < width; i++) { for (int j =

知道这几个节点的名称，就可以实例化这些节点，然后就对节点操作： bitmap.getPixels(intValues, 0, bitmap.getWidth(), 0, 0, bitmap.getWidth..., outputClasses); inferenceInterface.fetch(outputNames[3], outputNumDetections); 上面代码有几个方法： 首先是通过getPixels...d.inferenceInterface.graph(); 用g.operation(name)检查输入输出的operation是否存在 把输入数据转换成数组(Tensor)形式，比如图片：bitmap.getPixels
