## Name

VkSparseImageMemoryRequirements - Structure specifying sparse image memory requirements

Loading… please wait.

## C Specification

The `VkSparseImageMemoryRequirements` structure is defined as:

    // Provided by VK_VERSION_1_0
    typedef struct VkSparseImageMemoryRequirements {
        VkSparseImageFormatProperties    formatProperties;
        uint32_t                         imageMipTailFirstLod;
        VkDeviceSize                     imageMipTailSize;
        VkDeviceSize                     imageMipTailOffset;
        VkDeviceSize                     imageMipTailStride;
    } VkSparseImageMemoryRequirements;

## Members

- `formatProperties` is a VkSparseImageFormatProperties structure specifying properties of the image format.

- `imageMipTailFirstLod` is the first mip level at which image subresources are included in the mip tail region.

- `imageMipTailSize` is the memory size (in bytes) of the mip tail region. If `formatProperties.flags` contains VK_SPARSE_IMAGE_FORMAT_SINGLE_MIPTAIL_BIT, this is the size of the whole mip tail, otherwise this is the size of the mip tail of a single array layer. This value is guaranteed to be a multiple of the sparse block size in bytes.

- `imageMipTailOffset` is the opaque memory offset used with VkSparseImageOpaqueMemoryBindInfo to bind the mip tail region(s).

- `imageMipTailStride` is the offset stride between each array-layer’s mip tail, if `formatProperties.flags` does not contain VK_SPARSE_IMAGE_FORMAT_SINGLE_MIPTAIL_BIT (otherwise the value is undefined).
