# VkSamplerYcbcrConversionImageFormatProperties(3) Manual Page

## Name

VkSamplerYcbcrConversionImageFormatProperties - Structure specifying combined image sampler descriptor count for multi-planar images

Loading… please wait.

## C Specification

To determine the number of combined image samplers required to support a multi-planar format, add VkSamplerYcbcrConversionImageFormatProperties to the `pNext` chain of the VkImageFormatProperties2 structure in a call to `vkGetPhysicalDeviceImageFormatProperties2`.

The `VkSamplerYcbcrConversionImageFormatProperties` structure is defined as:

    // Provided by VK_VERSION_1_1
    typedef struct VkSamplerYcbcrConversionImageFormatProperties {
        VkStructureType    sType;
        void*              pNext;
        uint32_t           combinedImageSamplerDescriptorCount;
    } VkSamplerYcbcrConversionImageFormatProperties;

or the equivalent

    // Provided by VK_KHR_sampler_ycbcr_conversion
    typedef VkSamplerYcbcrConversionImageFormatProperties VkSamplerYcbcrConversionImageFormatPropertiesKHR;

## Members

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

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

- `combinedImageSamplerDescriptorCount` is the number of combined image sampler descriptors that the implementation uses to access the format.

## Description

Valid Usage (Implicit)

- VUID-VkSamplerYcbcrConversionImageFormatProperties-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_SAMPLER_YCBCR_CONVERSION_IMAGE_FORMAT_PROPERTIES`
