Functions

Type	Name	Description
void	ClearTextureData ()	Clears texture data being used. Can only be accessed on the render thread
EPixelFormat	GetPixelFormat ()	Returns the pixel format of this texture
FTexture2DRHIRef	GetRHIRef ()
bool	IsValid ()
void	Resize ( uint32 Width, uint32 Height )	Resize the texture. Can only be called on the render thread
void	SetRHIRef ( FTexture2DRHIRef InRenderTargetTexture, uint32 InWidth, uint32 InHeight )	Sets the RHI Ref to use.
void	SetTextureData ( FSlateTextureDataPtr NewTextureData )	Sets the bulk data for this texture.
void	SetTextureData ( FSlateTextureDataPtr NewTextureData, EPixelFormat InPixelFormat, ETextureCreateFlags InTexCreateFlags )	Sets the bulk data for this texture and the format of the rendering resource Note: Does not reinitialize the resource.

Overridden from FSlateShaderResource

	Type	Name	Description
	uint32	GetHeight ()	Gets the height of the resource.
	uint32	GetWidth ()	Gets the width of the resource.

Overridden from FSlateUpdatableTexture

Type	Name	Description
void	Cleanup ()	Deferred or Immediate cleanup of this data depending on what is required.
FRenderResource *	GetRenderResource ()	Gets the interface to the underlying render resource (may not always be used)
FSlateShaderResource *	GetSlateResource ()	Gets the interface to the underlying platform independent texture
void	ResizeTexture ( uint32 Width, uint32 Height )	Resize the texture.
void	UpdateTexture ( const TArray< uint8 >& Bytes )	Updates the texture contents via a byte array.
void	UpdateTextureThreadSafe ( const TArray< uint8 >& Bytes )	Updates the texture contents via a byte array making a copy first for thread safety
void	UpdateTextureThreadSafeRaw ( uint32 Width, uint32 Height, const void* Buffer, const FIntRect& Dirty )	Update the texture from a raw byte buffer.
void	UpdateTextureThreadSafeWithKeyedTextureHandle ( void* TextureHandle, int KeyLockVal, int KeyUnlockVal, const FIntRect& Dirty )	Update the texture from a shared texture handle.
void	UpdateTextureThreadSafeWithTextureData ( FSlateTextureData* TextureData )	Update the texture from a provided FSlateTextureData buffer, also transferring ownership of the texture
