C Specification

The set of usages for the created image view can be restricted compared to the parent image’s usage flags by chaining a VkImageViewUsageCreateInfo structure through the pNext member to 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
