Gondwana Game Engine
Gondwana is a cross-platform 2.5D game and rendering engine written in C#/.NET 8. It provides fine-grained control over rendering, timing, and scene composition, with built-in support for parallax, z-ordering, pixel overhang, collision detection, and particle effects. Gondwana targets desktop, mobile, and web platforms using SkiaSharp for graphics and NAudio for sound.

Provides a bitmap-based backbuffer implementation for rendering operations using SkiaSharp. This backbuffer maintains an in-memory bitmap surface that can be drawn to from a render thread and safely snapshotted for display on the UI thread. More...

Provides a bitmap-based backbuffer implementation for rendering operations using SkiaSharp. This backbuffer maintains an in-memory bitmap surface that can be drawn to from a render thread and safely snapshotted for display on the UI thread.
| Gondwana.Rendering.Backbuffers.BitmapBackbuffer.BitmapBackbuffer | ( | int | width, |
| int | height ) |
Initializes a new instance of the BitmapBackbuffer class with the specified dimensions.
| width | The initial width of the backbuffer in pixels. |
| height | The initial height of the backbuffer in pixels. |
|
virtual |
Releases all resources used by the BitmapBackbuffer.
This method disposes of the underlying SkiaSharp surface and bitmap resources. The disposal is thread-safe and idempotent.
Reimplemented from Gondwana.Rendering.Backbuffers.BackbufferBase.
|
get |
Gets the SKCanvas for drawing operations on this backbuffer.
The canvas instance that can be used to perform drawing operations.
Access to the canvas is thread-safe and synchronized using an internal lock.
|
getset |
Gets or sets the filter quality used when drawing bitmaps to the backbuffer.
The SKFilterQuality value that determines the quality of bitmap filtering during rendering. Default is SKFilterQuality.None for pixel-perfect rendering.
