title: How to take Instagram like square size picture
body: <p>I have a question of how to take a square size picture like Instagram. There might be posts like this but I haven't find any particularly helpful to me. Here's my problem: I tried to call getSupportedPictureSize() and see most of supported picture size are rectangular, while those few square size pictures are in low resolution. On the other hand if I set the preview size to square with rectangular picture then the preview looked stretched. Anyone has any idea of how I can do that? I would really appreciate it!</p>
