# VkSamplerCubicWeightsCreateInfoQCOM(3) Manual Page

## Name

VkSamplerCubicWeightsCreateInfoQCOM - Structure specifying sampler cubic weights

Loading… please wait.

## C Specification

The `VkSamplerCubicWeightsCreateInfoQCOM` structure is defined as:

    // Provided by VK_QCOM_filter_cubic_weights
    typedef struct VkSamplerCubicWeightsCreateInfoQCOM {
        VkStructureType             sType;
        const void*                 pNext;
        VkCubicFilterWeightsQCOM    cubicWeights;
    } VkSamplerCubicWeightsCreateInfoQCOM;

## Members

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

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

- `cubicWeights` is a VkCubicFilterWeightsQCOM value controlling which cubic weights are used.

## Description

If the `pNext` chain of VkSamplerCreateInfo includes a `VkSamplerCubicWeightsCreateInfoQCOM` structure, then that structure specifies which cubic weights are used.

If that structure is not present, `cubicWeights` is considered to be `VK_CUBIC_FILTER_WEIGHTS_CATMULL_ROM_QCOM`.

Valid Usage (Implicit)

- VUID-VkSamplerCubicWeightsCreateInfoQCOM-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_SAMPLER_CUBIC_WEIGHTS_CREATE_INFO_QCOM`

- VUID-VkSamplerCubicWeightsCreateInfoQCOM-cubicWeights-parameter
  `cubicWeights` must be a valid VkCubicFilterWeightsQCOM value
