在Android中获取位图图像的像素值

Question

I need to develop an android application which do some image processing on the image input. For this, I need to get the pixel values of the bitmap in either an array or an object. Can anyone help me to grab the pixel-level details of a bitmap image.

Thanks !

Answer 1

to get pixel array of bitmap

bitmap.getPixels(pixels, offset, stride, x, y, width, height);

every pixel/value in array will be represented as Color with ARGB value.

Answer 2

如果你想获得on像素的值，请执行此操作int pixel = bitmap.getPixel（x，y）;
