VkImageViewUsageCreateInfo(3)

# VkImageViewUsageCreateInfo(3) Manual Page

## Name

VkImageViewUsageCreateInfo - Specify the intended usage of an image view

## C Specification

The set of usages for the created image view can be restricted compared to the parent image’s `usage` flags by adding a `VkImageViewUsageCreateInfo` structure to the `pNext` chain of `VkImageViewCreateInfo`.

The `VkImageViewUsageCreateInfo` structure is defined as:

    typedef struct VkImageViewUsageCreateInfo {
        VkStructureType      sType;
        const void*          pNext;
        VkImageUsageFlags    usage;
    } VkImageViewUsageCreateInfo;

or the equivalent

    typedef VkImageViewUsageCreateInfo VkImageViewUsageCreateInfoKHR;

## Members

- `sType` is the type of this structure.

- `pNext` is `NULL` or a pointer to an extension-specific structure.

- `usage` is a bitmask describing the allowed usages of the image view. See VkImageUsageFlagBits for a description of the supported bits.

## Description

When this structure is chained to `VkImageViewCreateInfo` the `usage` field overrides the implicit `usage` parameter inherited from image creation time and its value is used instead for the purposes of determining the valid usage conditions of VkImageViewCreateInfo.

Valid Usage (Implicit)

- `sType` must be `VK_STRUCTURE_TYPE_IMAGE_VIEW_USAGE_CREATE_INFO`

- `usage` must be a valid combination of VkImageUsageFlagBits values

- `usage` must not be `0`
