# VkSamplerReductionModeCreateInfo(3) Manual Page

## Name

VkSamplerReductionModeCreateInfo - Structure specifying sampler reduction mode

Loading… please wait.

## C Specification

The `VkSamplerReductionModeCreateInfo` structure is defined as:

    // Provided by VK_VERSION_1_2
    typedef struct VkSamplerReductionModeCreateInfo {
        VkStructureType           sType;
        const void*               pNext;
        VkSamplerReductionMode    reductionMode;
    } VkSamplerReductionModeCreateInfo;

or the equivalent

    // Provided by VK_EXT_sampler_filter_minmax
    typedef VkSamplerReductionModeCreateInfo VkSamplerReductionModeCreateInfoEXT;

## Members

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

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

- `reductionMode` is a VkSamplerReductionMode value controlling how texture filtering combines texel values.

## Description

If the `pNext` chain of VkSamplerCreateInfo includes a `VkSamplerReductionModeCreateInfo` structure, then that structure includes a mode controlling how texture filtering combines texel values.

If this structure is not present, `reductionMode` is considered to be `VK_SAMPLER_REDUCTION_MODE_WEIGHTED_AVERAGE`.

Valid Usage (Implicit)

- VUID-VkSamplerReductionModeCreateInfo-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_SAMPLER_REDUCTION_MODE_CREATE_INFO`

- VUID-VkSamplerReductionModeCreateInfo-reductionMode-parameter
  `reductionMode` must be a valid VkSamplerReductionMode value
