To determine the memory requirements for an image resource without creating an object, call:
// Provided by VK_VERSION_1_3 void vkGetDeviceImageMemoryRequirements( VkDevice device, const VkDeviceImageMemoryRequirements* pInfo, VkMemoryRequirements2* pMemoryRequirements);
or the equivalent command
// Provided by VK_KHR_maintenance4 void vkGetDeviceImageMemoryRequirementsKHR( VkDevice device, const VkDeviceImageMemoryRequirements* pInfo, VkMemoryRequirements2* pMemoryRequirements);
deviceis the logical device intended to own the image.
pInfois a pointer to a VkDeviceImageMemoryRequirements structure containing parameters required for the memory requirements query.
pMemoryRequirementsis a pointer to a VkMemoryRequirements2 structure in which the memory requirements of the image object are returned.
