## Name

VkSamplerBlockMatchWindowCreateInfoQCOM - Structure specifying the block match window parameters

Loading… please wait.

## C Specification

The `VkSamplerBlockMatchWindowCreateInfoQCOM` structure is defined as:

    // Provided by VK_QCOM_image_processing2
    typedef struct VkSamplerBlockMatchWindowCreateInfoQCOM {
        VkStructureType                      sType;
        const void*                          pNext;
        VkExtent2D                           windowExtent;
        VkBlockMatchWindowCompareModeQCOM    windowCompareMode;
    } VkSamplerBlockMatchWindowCreateInfoQCOM;

## Members

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

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

- `windowExtent` is a VkExtent2D specifying a the width and height of the block match window.

- `windowCompareMode` is a VkBlockMatchWindowCompareModeQCOM specifying the compare mode.

## Description

Valid Usage

- VUID-VkSamplerBlockMatchWindowCreateInfoQCOM-WindowExtent-09210
  `WindowExtent` must not be larger than VkPhysicalDeviceImageProcessing2PropertiesQCOM::`maxBlockMatchWindow`

Valid Usage (Implicit)

- VUID-VkSamplerBlockMatchWindowCreateInfoQCOM-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_SAMPLER_BLOCK_MATCH_WINDOW_CREATE_INFO_QCOM`

- VUID-VkSamplerBlockMatchWindowCreateInfoQCOM-windowCompareMode-parameter
  `windowCompareMode` must be a valid VkBlockMatchWindowCompareModeQCOM value
