# VkPhysicalDeviceShaderImageFootprintFeaturesNV(3) Manual Page

## Name

VkPhysicalDeviceShaderImageFootprintFeaturesNV - Structure describing shader image footprint features that can be supported by an implementation

## C Specification

The `VkPhysicalDeviceShaderImageFootprintFeaturesNV` structure is defined as:

    typedef struct VkPhysicalDeviceShaderImageFootprintFeaturesNV {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           imageFootprint;
    } VkPhysicalDeviceShaderImageFootprintFeaturesNV;

## Members

- `imageFootprint` specifies whether the implementation supports the `ImageFootprintNV` SPIR-V capability.

## Description

See Texel Footprint Evaluation for more information.

If the `VkPhysicalDeviceShaderImageFootprintFeaturesNV` structure is included in the `pNext` chain of VkPhysicalDeviceFeatures2, it is filled with values indicating whether each feature is supported. `VkPhysicalDeviceShaderImageFootprintFeaturesNV` can also be included in the `pNext` chain of VkDeviceCreateInfo to enable features.

Valid Usage (Implicit)

- `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_IMAGE_FOOTPRINT_FEATURES_NV`
