UIView Automatic DPI Scaling

04 Jan 2022, 17:44

In 3.1.x, automatic DPI scaling is added. This is a nice feature but it creates limitations because my application supports custom scaling which is user configurable. I am able to 'disable' Noesis automatic scaling by commenting out NoesisView line 1949, _uiView.SetScale().

- Is there a preferred approach for disabling DPI scaling?
- Alternatively, can support be added for custom scaling, whereby I set 1.0 as a default value if I wish to disable it?
- Does this DPI scaling feature adapt to screen resolution changes?

Thank you!

Since 3.1 we are automatically setting the view scale to Screen.dpi in Unity. This takes into account pixel density. So for example, a resolution of 1024x1024 with 2x scale, will keep having a logical resolution of 1024 x 1024 but internally it is rendering to a 2048 x 2048 viewport. Note that this is not about screen resolution, changing the screen resolution will maintain the same scale.

This is implemented internally using a LayoutTransform at the root. Nothing stops you from having another LayoutTransform on your XAML with another scale for a user custom scale. Both effects will be cumulative.

Regarding disabling this in Unity, right now you need to change the code but I think we should add a flag in the Inspector. Could you please create a ticket about it?
