VkImageViewSampleWeightCreateInfoQCOM

If the pNext chain includes a VkImageViewSampleWeightCreateInfoQCOM structure, then that structure includes a parameter specifying the parameters for weight image views used in weight image sampling.

The VkImageViewSampleWeightCreateInfoQCOM structure is defined as:

typedef struct VkImageViewSampleWeightCreateInfoQCOM {
    VkStructureType sType;
    const void* pNext;
    VkOffset2D filterCenter;
    VkExtent2D filterSize;
    uint32_t numPhases;
} VkImageViewSampleWeightCreateInfoQCOM;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• filterCenter is a VkOffset2D describing the location of the weight filter origin.
• filterSize is a VkExtent2D specifying weight filter dimensions.
• numPhases is number of sub-pixel filter phases.

The filterCenter specifies the origin or center of the filter kernel, as described in Weight Sampling Operation. The numPhases describes the number of sub-pixel filter phases as described in Weight Sampling Phases.
