from_vulkan_format()

std::optional< ImageFormat > MayaFlux::Portal::Graphics::TextureLoom::from_vulkan_format ( vk::Format  vk_format )

static

Convert Vulkan format to Portal ImageFormat.

Reverse twin of to_vulkan_format. Returns std::nullopt for Vulkan formats with no ImageFormat equivalent rather than guessing.
