Android Bitmap圓角

標籤：

代碼如下：

 

 public Bitmap transform(Bitmap source) {        int size = Math.min(source.getWidth(), source.getHeight());        int x = (source.getWidth() - size) / 2;        int y = (source.getHeight() - size) / 2;        Bitmap squaredBitmap = Bitmap.createBitmap(source, x, y, size, size);        if (squaredBitmap != source) {            source.recycle();        }        Bitmap bitmap = Bitmap.createBitmap(size, size, source.getConfig());        Canvas canvas = new Canvas(bitmap);        Paint paint = new Paint();        BitmapShader shader = new BitmapShader(squaredBitmap, BitmapShader.TileMode.CLAMP, BitmapShader.TileMode.CLAMP);        paint.setShader(shader);        paint.setAntiAlias(true);        float r = size/2f;        canvas.drawCircle(r, r, r, paint);        squaredBitmap.recycle();        return bitmap;    }
