# VkPhysicalDeviceImageProcessing3FeaturesQCOM(3) Manual Page

## Name

VkPhysicalDeviceImageProcessing3FeaturesQCOM - Structure describing image processing features that can be supported by an implementation

## C Specification

The `VkPhysicalDeviceImageProcessing3FeaturesQCOM` structure is defined as:

    // Provided by VK_QCOM_image_processing3
    typedef struct VkPhysicalDeviceImageProcessing3FeaturesQCOM {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           imageGatherLinear;
        VkBool32           imageGatherExtendedModes;
        VkBool32           blockMatchExtendedClampToEdge;
    } VkPhysicalDeviceImageProcessing3FeaturesQCOM;

## Members

This structure describes the following features:

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

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

- `imageGatherLinear` indicates that the implementation supports shader modules that declare the `ImageGatherLinearQCOM` capability.

- `imageGatherExtendedModes` indicates that the implementation supports shader modules that declare the `ImageGatherExtendedModesQCOM` capability.

- `blockMatchExtendedClampToEdge` indicates that the implementation extends support for VK_SAMPLER_ADDRESS_MODE_CLAMP_TO_EDGE to both input images of all block matching operations.

## Description

If the `VkPhysicalDeviceImageProcessing3FeaturesQCOM` 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 `VkPhysicalDeviceImageProcessing3FeaturesQCOM`, 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.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceImageProcessing3FeaturesQCOM-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_IMAGE_PROCESSING_3_FEATURES_QCOM

Structure Chaining
