format_has_variant_storage()

MAYAFLUX_API bool MayaFlux::Kakshya::format_has_variant_storage

(

ImageFormat

format

)

True when a format decomposes into whole DataVariant elements.

False for DEPTH24 and DEPTH24_STENCIL8: both occupy 4 bytes per pixel in a packed layout that is not a whole number of uint8, uint16, or float elements. A container allocating storage_element_size * channels * pixels for either will not match what a bytes_per_pixel-sized write path produces.

Derived from the format tables rather than enumerated, so it stays correct if a format is added.

Parameters

format

Pixel format.
