Inheritance diagram for Gondwana.Avalonia.Rendering.AvaloniaGpuRenderSurfaceAdapter:

Public Member Functions
override void	Present (SKImage bufferImage, SKRectI bufferRect, SKRect destRect)
	Not used in the GL-thread path. The image is disposed immediately to avoid a leak.
void	Dispose ()
	Releases all resources used by the AvaloniaGpuRenderSurfaceAdapter.
Public Member Functions inherited from Gondwana.Rendering.RenderSurfaceAdapterBase
Point	AdapterPxToScreenPx (PointF adapterPx)
	Converts adapter input to logical ScreenPx, retaining outside coordinates for capture/leave.
void	DrawImage (SKCanvas canvas, SKImage image, SKColor clearColor)
	Presents a complete image using the same transform as pointer normalization.
void	Present (SKImage bufferImage, SKRectI bufferRect, SKRect destRect)
	Presents the specified portion of the Backbuffer image to the destination rectangle on the RenderSurfaceAdapter.

Properties
SKColor	ClearColor = SKColors.Black `[get, set]`
	Gets or sets the color used to clear the surface before rendering.
Properties inherited from Gondwana.Rendering.RenderSurfaceAdapterBase
PresentationTransform	Presentation `[get]`
	Current immutable aspect-preserving mapping of Backbuffer ScreenPx to adapter pixels.
float	PresentationScale `[get]`
	Current derived presentation scale; adapter resize does not resize the Backbuffer.
int	Width `[get, protected set]`
	Gets the current width of the render surface in pixels.
int	Height `[get, protected set]`
	Gets the current height of the render surface in pixels.

Additional Inherited Members
Protected Member Functions inherited from Gondwana.Rendering.RenderSurfaceAdapterBase
	RenderSurfaceAdapterBase (int destWidth, int destHeight)
	Initializes a new instance of the RenderSurfaceAdapterBase class with the specified dimensions.
	RenderSurfaceAdapterBase (int destWidth, int destHeight, bool initialSizeAvailable)
	Constructs an adapter whose initial layout may still be pending.
void	SetDestinationSize (int destWidth, int destHeight)
	Sets the destination size of the render surface and raises the Resized event if the dimensions have changed.
Events inherited from Gondwana.Rendering.RenderSurfaceAdapterBase
Action< RenderSurfaceAdapterResizedEventArgs >?	Resized
	Occurs when the render surface adapter is resized.

Detailed Description

Provides a GPU-accelerated render surface adapter for Avalonia, backed by global::Avalonia.OpenGL.Controls.OpenGlControlBase.

The adapter's primary role is to track the physical-pixel dimensions of the render target (used to fit the logical Backbuffer into the physical presentation surface) and to post RequestNextFrameRendering() to the UI thread after each engine foreground cycle. All actual GL operations — surface creation, rendering, and presentation — are handled by AvaloniaGpuRenderSurfaceControl.

VSync: The GpuBackbuffer.VSync property has no effect when used with this adapter; swap-interval control is delegated to Avalonia's compositor.

Platform support: Requires a GPU-capable Avalonia backend (Windows/macOS/Linux desktop). Not suitable for WebAssembly (WASM) targets; use AvaloniaBitmapRenderSurfaceAdapter for cross-platform / WASM scenarios.
