💭 Why the Photo Result Does Not Come Out in the Specified Aspect Ratio

[seereal-beomjin]

Question

When I set photoAspectRatio to 1/1 and photoResolution to 3048, which is a 1:1 ratio, and take a picture, the resulting width and height do not come out at 1:1.

I'm using samsung galaxy s10

What I tried

const format = useCameraFormat(device, [
    {videoAspectRatio: ratio}, // 1:1
    {photoAspectRatio: ratio}, // 1:1 
    {photoResolution: {width: 3048, height: 3048}},
  ]);

the output is

{"height": 288, "isMirrored": false, "isRawPhoto": false, "orientation": "landscape-left", "path": "/data/user/0/com.../cache/mrousavy2801553129656230601.jpg", "width": 352}

That's not how formats work. Please read the formats documentation. Formats is what your phone natively supports, 1:1 ratio is probably not natively supported as sensors are usually 4:3.

You need to crop the photo yourself after taking it.
