## Name

VkPhysicalDeviceImageProcessingPropertiesQCOM - Structure containing image processing properties

Loading… please wait.

## C Specification

The `VkPhysicalDeviceImageProcessingPropertiesQCOM` structure is defined as:

    // Provided by VK_QCOM_image_processing
    typedef struct VkPhysicalDeviceImageProcessingPropertiesQCOM {
        VkStructureType    sType;
        void*              pNext;
        uint32_t           maxWeightFilterPhases;
        VkExtent2D         maxWeightFilterDimension;
        VkExtent2D         maxBlockMatchRegion;
        VkExtent2D         maxBoxFilterBlockSize;
    } VkPhysicalDeviceImageProcessingPropertiesQCOM;

## Members

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

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

- `maxWeightFilterPhases` is the maximum value that can be specified for VkImageViewSampleWeightCreateInfoQCOM::`numPhases` in weight image sampling operations.

- `maxWeightFilterDimension` is a VkExtent2D describing the largest dimensions (`width` and `height`) that can be specified for VkImageViewSampleWeightCreateInfoQCOM::`filterSize`.

- `maxBlockMatchRegion` is a VkExtent2D describing the largest dimensions (`width` and `height`) that can be specified for `blockSize` in block matching operations.

- `maxBoxFilterBlockSize` is a VkExtent2D describing the maximum dimensions (`width` and `height`) that can be specified for `blocksize` in box filter sampling operations.

## Description

If the `VkPhysicalDeviceImageProcessingPropertiesQCOM` structure is included in the `pNext` chain of the VkPhysicalDeviceProperties2 structure passed to vkGetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

These are properties of the image processing information of a physical device.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceImageProcessingPropertiesQCOM-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_IMAGE_PROCESSING_PROPERTIES_QCOM`
