Question

enter image description here 我试图获取jpeg图像中像素的RGB值。这是我在2020％放大率下从photoshop拍摄的原始图像的屏幕截图

我在Adobe自己制作了图像（“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);
    }
}

我检查日志，但我得到错误的RGB值。我知道这个原因我把红色（255,0,0），蓝色（0,0,255）和绿色（0,255,0）放在那些特定的方块（像素）中。

这是日志：

我尝试将其保存在8bitJpeg ...和16bitJpeg中...但我得到的值是错误的。有人可以帮助我，并解释一下为什么会发生这种情况？

例如4thRow，第1个像素（即0,3）是Green = 0,255,0。

但其日志显示“0/3 =红色：1绿色：0蓝色：10”

Answer 1

我终于成功解决了问题中最令人费解的部分。

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
PS中图像的完全放大显示许多小网格。虽然它说30x11 ..它实际上是双倍的。这意味着长度加倍，宽度加倍。所以我用像素制作的真实图像是60x22。所以很明显我在网格上看到的（0,3）GREEN，实际上是4像素（0,6）（0,7）（1,6）（1,7）

Bitmap.getPixel（j，i）返回错误的RGB值？
