Member Typedef Documentation

using ConversionFunction = void(*)(const void * src, size_t numTexels, void * dst)

Converts given number of texels.

Conversion can be in-place if the ends of the source and destination buffers align.

Definition at line 52 of file textureUtils.h.

static HDST_API std::vector<HioImageSharedPtr> GetAllMipImages	(	const std::string &	filePath,
		HioImage::SourceColorSpace	sourceColorSpace
	)

static

Get all mip levels from a file.

static HDST_API HgiFormat GetHgiFormat	(	HioFormat	hioFormat,
		bool	premultiplyAlpha
	)

static

Get the Hgi format suitable for a given Hio format.

Premultiply alpha indicates whether a conversion function multiplying RGB with alpha should be created.

static HDST_API ConversionFunction GetHioToHgiConversion	(	HioFormat	hioFormat,
		bool	premultiplyAlpha
	)

static

Returns the conversion function to return a HioFormat to the corresponding HgiFormat given by GetHgiFormat.

Returns nullptr if no conversion necessary.
