Divide Image into parts

Question

I have images stored into sd card. I want to divide the image into sixteen equal parts. How to do it using bitmap?

Answer 1

Give it a try to somthing like this:

DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);

final int width = dm.widthPixels;
final int height = dm.heightPixels;

final int pixelByCol = width / 4;
final int pixelByRow = height / 4; 

List bs = new ArrayList();

Bitmap image = 

for (int i = 0; i < 4) {
    for (int j = 0; j < 4) {
        int startX = pixelByCol * i;
        int startY = pixelByRow * j;
        Bitmap b = Bitmap.createBitmap(image, startX, startY, pixelByCol, pixelByRow);
        bs.add(b);
    }
}

bs <- your bitmaps
