Class VulkanBackendImage

java.lang.Object

icyllis.arc3d.engine.BackendImage

icyllis.arc3d.vulkan.VulkanBackendImage

public final class VulkanBackendImage
extends BackendImage

When importing external memory, mMemoryHandle is POSIX file descriptor or Win32 NT handle (though HANDLE is defined as void*, we can safely truncate it because Win32 handles are 32-bit significant). If it is an NT handle, it must be released manually by the memory exporter (e.g. Vulkan).
