Usage

From source file:Main.java

public static Bitmap resizeDownAndCropCenter(Bitmap bitmap, int size, boolean recycle) {
    int w = bitmap.getWidth();
    int h = bitmap.getHeight();
    int minSide = Math.min(w, h);

        return bitmap;
    size = Math.min(size, minSide);

    float scale = Math.max((float) size / bitmap.getWidth(), (float) size / bitmap.getHeight());
    Bitmap target = Bitmap.createBitmap(size, size, getConfig(bitmap));
    int width = Math.round(scale * bitmap.getWidth());
    int height = Math.round(scale * bitmap.getHeight());
    Canvas canvas = new Canvas(target);
    canvas.translate((size - width) / 2f, (size - height) / 2f);
    canvas.scale(scale, scale);//  w w w. ja v  a2  s  .c o m
    Paint paint = new Paint(Paint.FILTER_BITMAP_FLAG | Paint.DITHER_FLAG);
