How do I fit aspect ratio

Hello.
I use NREAL Air.
I want to display picture selected for android smartphone on image object in Unity.
But, I cannot fit aspect ratio for a picture.
I use the package.

If you know reason, tell me please.

Hi, could you please show me what ratio you get in the Unity emulator?

I have set the size of the Image to 500 x 500.


The emulator does not work, but the pictures fit the size of the Image when tested on the actual device.

OK, thanks for your further info. Then the issue only happens in the emulator. Maybe there is a compatibility issue between the Image picker and Unity?
