Detailed Description

Texture resource type for webbrowser textures.

Constructor & Destructor Documentation

◆ FWebBrowserTextureResource()

FWebBrowserTextureResource::FWebBrowserTextureResource	(	UWebBrowserTexture &	InOwner,
		FIntPoint &	InOwnerDim,
		SIZE_T &	InOwnerSize
	)

Creates and initializes a new instance.

Parameters

InOwner	The Movie texture object to create a resource for (must not be nullptr).
InOwnerDim	The initial width and height of the texture.
InOwnerSize	The initial memory allocated to the texture.

◆ ~FWebBrowserTextureResource()

virtual FWebBrowserTextureResource::~FWebBrowserTextureResource ( )

inlinevirtual

Virtual destructor.

Member Function Documentation

◆ ClearTexture()

void FWebBrowserTextureResource::ClearTexture	(	FRHICommandList &	RHICmdList,
		const FLinearColor &	ClearColor
	)

protected

Clear the texture using the given clear color.

Parameters

ClearColor The clear color to use.

◆ CopySample()

void FWebBrowserTextureResource::CopySample	(	FRHICommandListBase &	RHICmdList,
		const TSharedPtr< FWebBrowserTextureSample, ESPMode::ThreadSafe > &	Sample,
		const FLinearColor &	ClearColor
	)

protected

Render the given texture sample by using it as or copying it to the render target.

Parameters

Sample	The texture sample to copy.
ClearColor	The clear color to use for the output texture.

◆ GetFriendlyName()

FString FWebBrowserTextureResource::GetFriendlyName ( ) const

overridevirtual

Returns: The resource's friendly name. Typically a UObject name.

Reimplemented from FTexture.

◆ GetSizeX()

uint32 FWebBrowserTextureResource::GetSizeX ( ) const

overridevirtual

Returns the width of the texture in pixels.

Reimplemented from FTexture.

◆ GetSizeXY()

FIntPoint FWebBrowserTextureResource::GetSizeXY ( ) const

overridevirtual

Implements FRenderTarget.

◆ GetSizeY()

uint32 FWebBrowserTextureResource::GetSizeY ( ) const

overridevirtual

Returns the height of the texture in pixels.

Reimplemented from FTexture.

◆ InitRHI()

void FWebBrowserTextureResource::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 FWebBrowserTextureResource::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.

◆ Render()

void FWebBrowserTextureResource::Render	(	FRHICommandList &	RHICmdList,
		const FRenderParams &	Params
	)

Render the texture resource.

This method is called on the render thread by the WebBrowserTexture that owns this texture resource to clear or redraw the resource using the given parameters.

Parameters

Params Render parameters.

◆ UpdateResourceSize()

void FWebBrowserTextureResource::UpdateResourceSize ( )

protected

Calculates the current resource size and notifies the owner texture.

◆ UpdateTextureReference()

void FWebBrowserTextureResource::UpdateTextureReference	(	FRHICommandListBase &	RHICmdList,
		FRHITexture *	NewTexture
	)

protected

Set the owner's texture reference to the given texture.

Parameters

NewTexture The texture to set.
