Functions
uint8	ClampNumMips (uint8 InNumMips, const FIntPoint &InDim)
uint8	CalcGeneratedNumMips (const IMediaTextureSample &InSample, bool bInEnableGenMips)
	Calculates the target number of generated mips for a given sample.
uint8	CalcTextureNumMips (const IMediaTextureSample &InSample, bool bInEnableGenMips)
	Calculates the expected texture resource number of mips for the given sample. Sample source mips take priority over generated ones.

Function Documentation

CalcGeneratedNumMips()

uint8 UE::MediaTexture::Private::CalcGeneratedNumMips	(	const IMediaTextureSample &	InSample,
		bool	bInEnableGenMips
	)

Calculates the target number of generated mips for a given sample.

Parameters

InSample	Decoded sample.
bInEnableGenMips	Indicate if mip generation is enabled.

Returns

Expected number of generated mips.

CalcTextureNumMips()

uint8 UE::MediaTexture::Private::CalcTextureNumMips	(	const IMediaTextureSample &	InSample,
		bool	bInEnableGenMips
	)

Calculates the expected texture resource number of mips for the given sample. Sample source mips take priority over generated ones.

Parameters

InSample	Decoded sample.
bInEnableGenMips	Indicate if mip generation is enabled.

Returns

Expected number of mips.

ClampNumMips()

uint8 UE::MediaTexture::Private::ClampNumMips	(	uint8	InNumMips,
		const FIntPoint &	InDim
	)

Clamps the number of mips to the maximum needed mips given the texture dimensions.
