RenderSurfaceAdapterBase()

Gondwana.Rendering.RenderSurfaceAdapterBase.RenderSurfaceAdapterBase ( int destWidth, int destHeight )

protected

Initializes a new instance of the RenderSurfaceAdapterBase class with the specified dimensions.

Parameters

destWidth	The initial width of the render surface in pixels.
destHeight	The initial height of the render surface in pixels.

Member Function Documentation

Present()

void Gondwana.Rendering.RenderSurfaceAdapterBase.Present ( SKImage bufferImage, SKRectI bufferRect, SKRect destRect )

abstract

Presents the specified portion of the Backbuffer image to the destination rectangle on the RenderSurfaceAdapter.

The method maps the specified region of the buffer image to the destination rectangle, scaling or transforming as necessary. Callers must ensure that the dimensions and coordinates of bufferRect and destRect are valid.

Parameters

bufferImage	The source image from which to present. Cannot be null.
bufferRect	The rectangular region of the buffer image to present. Coordinates are in the buffer image's space.
destRect	The rectangular region in the destination space where the presented content will be drawn.

SetDestinationSize()

void Gondwana.Rendering.RenderSurfaceAdapterBase.SetDestinationSize ( int destWidth, int destHeight )

protected

Sets the destination size of the render surface and raises the Resized event if the dimensions have changed.

Parameters

destWidth	The new width of the render surface in pixels.
destHeight	The new height of the render surface in pixels.

If the specified dimensions are the same as the current dimensions, this method returns without making changes or raising the Resized event.

Property Documentation

Height

int Gondwana.Rendering.RenderSurfaceAdapterBase.Height

getprotected set

Gets the current height of the render surface in pixels.

The height of the render surface.

Width

int Gondwana.Rendering.RenderSurfaceAdapterBase.Width

getprotected set

Gets the current width of the render surface in pixels.

The width of the render surface.

Event Documentation

Resized

Action<RenderSurfaceAdapterResizedEventArgs>? Gondwana.Rendering.RenderSurfaceAdapterBase.Resized

Occurs when the render surface adapter is resized.

This event is raised when the Width or Height properties change, providing both the old and new dimensions in the event arguments.
