storage_element_size() [2/2]

MAYAFLUX_API size_t MayaFlux::Kakshya::storage_element_size

(

Portal::Graphics::ImageFormat

format

)

Byte width of the DataVariant element backing a given ImageFormat.

Returns 1 for uint8 storage, 2 for uint16, 4 for float. Defaults to 1 for any format without an explicit mapping.

Size determines the alternative unambiguously only because DataVariant's pixel alternatives are uint8, uint16, and float: 4 means float, not uint32. Half-float formats return 2, since the uint16 bits are the IEEE-754 binary16 encoding rather than a UNORM value; consumers needing the decoded magnitude must check is_float_format().

Parameters

format

Pixel format.

Returns

Element size in bytes.
