How to manipulate image at pixel level. I want to extract information from image by rearranging its pixel. Any help to solve this problem is appreciated.

Answer 1

To extract the information from the image you need the below code

import android.graphics.Color;

    int[] pixels = new int[myBitmap.getHeight()*myBitmap.getWidth()];
    myBitmap.getPixels(pixels, 0, myBitmap.getWidth(), 0, 0, myBitmap.getWidth(), myBitmap.getHeight());
    for (int i=0; i<myBitmap.getWidth()*5; i++)
        pixels[i] = Color.BLUE;
    myBitmap.setPixels(pixels, 0, myBitmap.getWidth(), 0, 0, myBitmap.getWidth(), myBitmap.getHeight());
