| Methods | |
|---|---|
| ApplyPostProcessing() | Applies post-processing effects to the current frame. Only works if post-processing is enabled via options. |
| BeginFrame() | Begins a new frame. Silently returns (no-op) when the renderer is not initialized, suspended, or unable to acquire GPU resources. Draw calls issued without a successful BeginFrame() are dropped. |
| DrainPendingUploads() | Releases all pending upload resources unconditionally. The caller must ensure SDL3.SDL.WaitForGPUIdle(System.IntPtr) has completed before calling this method so that all fences are already signaled. |
| DrawTexture(ITexture, float, float) | Draw texture at position (float x, y, top-left anchor). |
| DrawTexture(ITexture, float, float, float, float) | Draw texture at position with explicit width/height (top-left anchor). |
| DrawTexture(ITexture, Vector2) | Draw texture at position (Vector2, top-left anchor). |
| DrawTexture(ITexture, Vector2, Nullable<Rectangle>, Nullable<Vector2>, float, Nullable<Vector2>, Nullable<Color>, SpriteFlip) | Draw a texture with full control over transform, origin, scale, and flip. |
| EndFrame() | Ends the current frame and submits the command buffer. Silently returns (no-op) when the renderer is not initialized or disposed. When suspended, pending draw calls are discarded but the command buffer is still submitted so GPU resources are not leaked. |
| OnWindowResized(WindowResizedEvent) | |
| PopRenderTarget() | Pop the current render target from the stack. |
| PushRenderTarget(IRenderTarget) | Push the current render target onto a stack and set a new one. Useful for nested render-to-texture operations. |
| RenderGlyphs(ReadOnlySpan<char>, float, float, Color, ITexture, float, float, float, float, bool, float, Action<float,float,float>, Nullable<float>) |
