save_image()

bool MayaFlux::IO::save_image	(	const std::shared_ptr< Core::VKImage > &	image,
		const std::string &	filepath,
		const ImageWriteOptions &	options = {}
	)

Save a VKImage directly to disk via the ImageWriter registry.

Combines download_image() with ImageWriterRegistry::create_writer(). The file extension selects the writer. Format-variant compatibility is the writer's responsibility: saving a float VKImage as PNG will fail at the writer (uint8 mismatch), saving a uint8 VKImage as EXR will fail too.

Parameters

image	VKImage to save.
filepath	Destination path with extension.
options	Format-specific writer options.

Returns

True on success.
