public static Bitmap getBitmap(String path) {
Bitmap bt = BitmapFactory.decodeFile(path);
return bt;
}

// 指定大小載入圖片
public static Bitmap getBitmap(String path, int size) {
Options op = new Options();
op.inSampleSize = size;
Bitmap bt = BitmapFactory.decodeFile(path, op);
return bt; www.2cto.com
}

// 按寬高壓縮載入圖片
public static Bitmap getBitmap(String path, int width, int heigh) {
Options op = new Options();
op.inJustDecodeBounds = true;
Bitmap bt = BitmapFactory.decodeFile(path, op);
int xScale = op.outWidth / width;
int yScale = op.outHeight / heigh;
op.inSampleSize = xScale > yScale ? xScale : yScale;
op.inJustDecodeBounds = false;
bt = BitmapFactory.decodeFile(path, op);
return bt;
}
