# VkSamplerReductionModeCreateInfo(3) Manual Page

## Name

VkSamplerReductionModeCreateInfo - Structure specifying sampler reduction mode

## C Specification

The `VkSamplerReductionModeCreateInfo` structure is defined as:

    typedef struct VkSamplerReductionModeCreateInfo {
        VkStructureType           sType;
        const void*               pNext;
        VkSamplerReductionMode    reductionMode;
    } VkSamplerReductionModeCreateInfo;

or the equivalent

    typedef VkSamplerReductionModeCreateInfo VkSamplerReductionModeCreateInfoEXT;

## Members

- `sType` is the type of this structure.

- `pNext` is `NULL` or a pointer to an extension-specific 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 that controls 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)

- `sType` must be `VK_STRUCTURE_TYPE_SAMPLER_REDUCTION_MODE_CREATE_INFO`

- `reductionMode` must be a valid VkSamplerReductionMode value
