Member Function Documentation

◆ ClampSize()

void FSlateTextureRenderTarget2DResource::ClampSize	(	int32	SizeX,
		int32	SizeY
	)

overridevirtual

Reimplemented from FTextureRenderTargetResource.

◆ GetDisplayGamma()

float FSlateTextureRenderTarget2DResource::GetDisplayGamma ( ) const

overridevirtual

Render target resource should be sampled in linear color space

Returns: display gamma expected for rendering to this render target

Reimplemented from FTextureRenderTargetResource.

◆ GetSizeX()

uint32 FSlateTextureRenderTarget2DResource::GetSizeX ( ) const

overridevirtual

Returns the width of the texture in pixels.

Implements FTextureRenderTargetResource.

◆ GetSizeXY()

FIntPoint FSlateTextureRenderTarget2DResource::GetSizeXY ( ) const

overridevirtual

Implements FRenderTarget.

◆ GetSizeY()

uint32 FSlateTextureRenderTarget2DResource::GetSizeY ( ) const

overridevirtual

Returns the height of the texture in pixels.

Implements FTextureRenderTargetResource.

◆ InitRHI()

void FSlateTextureRenderTarget2DResource::InitRHI ( FRHICommandListBase & RHICmdList )

overridevirtual

Initializes the RHI resources used by this resource. Called when entering the state where both the resource and the RHI have been initialized. This is only called by the rendering thread.

Reimplemented from FRenderResource.

◆ ReleaseRHI()

void FSlateTextureRenderTarget2DResource::ReleaseRHI ( )

overridevirtual

Releases the RHI resources used by this resource. Called when leaving the state where both the resource and the RHI have been initialized. This is only called by the rendering thread.

Reimplemented from FTexture.

◆ SetSize()

void FSlateTextureRenderTarget2DResource::SetSize	(	int32	InSizeX,
		int32	InSizeY
	)

virtual

Resizes the render target

◆ UpdateDeferredResource()

void FSlateTextureRenderTarget2DResource::UpdateDeferredResource	(	FRHICommandListImmediate &	RHICmdList,
		bool	bClearRenderTarget = `true`
	)

overrideprotectedvirtual

Updates (resolves) the render target texture. Optionally clears the contents of the render target to green. This is only called by the rendering thread.

Implements FDeferredUpdateResource.
