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
isNULL
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.
If the application wishes to use a VkDevice with any features
described by VkPhysicalDeviceImageRobustnessFeatures
, it must add an instance of the structure,
with the desired feature members set to VK_TRUE
, to the pNext
chain of VkDeviceCreateInfo when creating the VkDevice.
