Detailed Description

Override for font textures that saves data between Init and ReleaseRHI to ensure all characters in the font texture exist if the rendering resource has to be recreated between caching new characters

Constructor & Destructor Documentation

◆ FSlateFontTextureRHIResource()

FSlateFontTextureRHIResource::FSlateFontTextureRHIResource ( uint32  InWidth,
uint32  InHeight,
ESlateFontAtlasContentType  InContentType 
)

Constructor. Initializes the texture

Parameters
InWidthThe width of the texture
InHeightThe height of the texture

Member Function Documentation

◆ GetContentType()

ESlateFontAtlasContentType FSlateFontTextureRHIResource::GetContentType ( ) const
inline

Returns texture content type

◆ GetFriendlyName()

virtual FString FSlateFontTextureRHIResource::GetFriendlyName ( ) const
inlineoverridevirtual
Returns
The resource's friendly name. Typically a UObject name.

Reimplemented from FTexture.

◆ GetHeight()

virtual uint32 FSlateFontTextureRHIResource::GetHeight ( ) const
inlineoverridevirtual

Gets the height of the resource.

Returns
Resource height(in pixels).

Implements FSlateShaderResource.

◆ GetSizeX()

virtual uint32 FSlateFontTextureRHIResource::GetSizeX ( ) const
inlineoverridevirtual

FTextureResource interface

Reimplemented from FTexture.

◆ GetSizeY()

virtual uint32 FSlateFontTextureRHIResource::GetSizeY ( ) const
inlineoverridevirtual

Returns the height of the texture in pixels.

Reimplemented from FTexture.

◆ GetWidth()

virtual uint32 FSlateFontTextureRHIResource::GetWidth ( ) const
inlineoverridevirtual

FSlateShaderResource interface

Implements FSlateShaderResource.

◆ InitRHI()

void FSlateFontTextureRHIResource::InitRHI ( FRHICommandListBase &  RHICmdList)
overridevirtual

FRenderResource interface

Reimplemented from FRenderResource.

◆ ReleaseRHI()

void FSlateFontTextureRHIResource::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.
