VkSubsampledImageFormatPropertiesEXT

To determine the number of image descriptors required to support a subsampled image created with VK_IMAGE_CREATE_SUBSAMPLED_BIT_EXT, add VkSubsampledImageFormatPropertiesEXT to the pNext chain of the VkImageFormatProperties2 structure in a call to vkGetPhysicalDeviceImageFormatProperties2.

The VkSubsampledImageFormatPropertiesEXT structure is defined as:

typedef struct VkSubsampledImageFormatPropertiesEXT {
    VkStructureType sType;
    const void* pNext;
    uint32_t subsampledImageDescriptorCount;
} VkSubsampledImageFormatPropertiesEXT;

pub struct SubsampledImageFormatPropertiesEXT {
    s_type: vk::StructureType,
    p_next: *const c_void,
    subsampled_image_descriptor_count: u32,
}

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• subsampledImageDescriptorCount is the number of image descriptors that the implementation uses to access the image.
