VkSamplerReductionModeCreateInfoEXT(3)

# VkSamplerReductionModeCreateInfoEXT(3) Manual Page

## Name

VkSamplerReductionModeCreateInfoEXT - Structure specifying sampler reduction mode

## C Specification

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

The `VkSamplerReductionModeCreateInfoEXT` structure is defined as:

    typedef struct VkSamplerReductionModeCreateInfoEXT {
        VkStructureType              sType;
        const void*                  pNext;
        VkSamplerReductionModeEXT    reductionMode;
    } VkSamplerReductionModeCreateInfoEXT;

## Members

- `sType` is the type of this structure.

- `pNext` is `NULL` or a pointer to an extension-specific structure.

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

## Description

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

Valid Usage (Implicit)

- `sType` must be `VK_STRUCTURE_TYPE_SAMPLER_REDUCTION_MODE_CREATE_INFO_EXT`

- `reductionMode` must be a valid VkSamplerReductionModeEXT value
