【问题描述】：

我正在尝试获取 jpeg 图像中像素的 RGB 值。这是我在 Photoshop 中以 2020% 放大的原始图像的屏幕截图

我已经在 Adobe 中制作了我自己的图像（“trial.jpg”），并在图像中放置了一些红色、绿色和蓝色像素，这是一个从 0,0 开始的 (30,11) 像素网格（即左上角）。

这是我的代码：

for(int i = 0; i < 11; i++) {
   for(int j = 0; j < 30; j++) 
   {
        int c = garage.getPixel(j,i);
        int red1 = Color.red(c);        
        int green1 = Color.green(c);
        int blue1 = Color.blue(c);

        Log.e("PIXEL",j + "/" + i +   "= Red: " + red1 +"  Green: " + green1 + " Blue: " + blue1);
    }
}

我检查了日志，但我得到了错误的 RGB 值。我知道这是因为我将红色（255,0,0），蓝色（0,0,255）和绿色（0,255,0）放在那些特定的正方形（像素）中。

这是日志：

我尝试将其保存在 8bitJpeg... 和 16bitJpeg... 但我得到的值是错误的。有人可以帮助我，并解释为什么会这样吗？

例如，第 4 行第 1 个像素（即 0,3）是绿色 = 0,255,0。

但它的日志显示“0/3= Red: 1 Green: 0 Blue: 10”

【问题讨论】：

你能显示logcat的输出吗？
嗨阿米特，我已经用图像和日志重新编辑了我的问题。如果您能找出问题所在，请告诉我。希望这更清楚。

【解决方案1】：

我终于设法破解了问题中主要令人费解的部分。

通过不同的压缩方法保存 jpeg 会改变您设置像素的 RGB 内容。因此，像 .png
在 PS 中完全放大图像会显示许多小网格。所以虽然它说 30x11.. 它实际上是双倍的。所以这意味着长度加倍，宽度加倍。所以我以像素为单位制作的真实图像是 60x22。所以很明显，我在网格上看到的 (0,3)GREEN，实际上是真实图像上 (0,6) (0,7) (1,6) (1,7) 处的 4 个像素
