# VkPhysicalDeviceImageRobustnessFeatures(3) Manual Page

## Name

VkPhysicalDeviceImageRobustnessFeatures - Structure describing the out-of-bounds behavior for an implementation

Loading… please wait.

## C Specification

The `VkPhysicalDeviceImageRobustnessFeatures` structure is defined as:

    // Provided by VK_VERSION_1_3
    typedef struct VkPhysicalDeviceImageRobustnessFeatures {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           robustImageAccess;
    } VkPhysicalDeviceImageRobustnessFeatures;

or the equivalent

    // Provided by VK_EXT_image_robustness
    typedef VkPhysicalDeviceImageRobustnessFeatures VkPhysicalDeviceImageRobustnessFeaturesEXT;

## Members

This structure describes the following feature:

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

## Description

- `robustImageAccess` indicates whether image accesses are tightly bounds-checked against the dimensions of the image view. Invalid texels resulting from out of bounds image loads will be replaced as described in Texel Replacement, with either (0,0,1) or (0,0,0) values inserted for missing G, B, or A components based on the format.

If the `VkPhysicalDeviceImageRobustnessFeatures` structure is included in the `pNext` chain of the VkPhysicalDeviceFeatures2 structure passed to vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. `VkPhysicalDeviceImageRobustnessFeatures` can also be used in the `pNext` chain of VkDeviceCreateInfo to selectively enable these features.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceImageRobustnessFeatures-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_IMAGE_ROBUSTNESS_FEATURES`
