Interface IScreenView

Namespace: MicroEngine.Core
Assembly: MicroEngine.dll
Guide: The world view and the UI view

The UI view of a platform that draws at the window’s resolution: a capability (TryGetCapability``1) of the SDL and raylib platforms and of the headless platform. The world is drawn into the canvas (BeginFrame) and scaled into WorldFrame; the UI view is drawn in UI units (window pixels divided by UiScale) and composited over it, so its text and shapes have the window’s resolution whatever the canvas’s.
