query_surface_format()

MAYAFLUX_API Core::GraphicsSurfaceInfo::SurfaceFormat MayaFlux::Kakshya::query_surface_format

(

const std::shared_ptr< Core::Window > &

window

)

Query the actual vk::Format in use by the window's live swapchain, translated back to the MayaFlux surface format enum.

This is the ground truth for readback allocation — it reflects what the driver actually negotiated, which may differ from the value requested in GlobalGraphicsConfig when the preferred format was unavailable.

Parameters

window

Target window.

Returns

Actual surface format. Returns B8G8R8A8_SRGB if the window has no registered swapchain.
