## C Specification

The `VkQueueFamilyDataGraphOpticalFlowPropertiesARM` structure is defined as:

    // Provided by VK_ARM_data_graph_optical_flow
    typedef struct VkQueueFamilyDataGraphOpticalFlowPropertiesARM {
        VkStructureType                           sType;
        void*                                     pNext;
        VkDataGraphOpticalFlowGridSizeFlagsARM    supportedOutputGridSizes;
        VkDataGraphOpticalFlowGridSizeFlagsARM    supportedHintGridSizes;
        VkBool32                                  hintSupported;
        VkBool32                                  costSupported;
        uint32_t                                  minWidth;
        uint32_t                                  minHeight;
        uint32_t                                  maxWidth;
        uint32_t                                  maxHeight;
    } VkQueueFamilyDataGraphOpticalFlowPropertiesARM;

## Members

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

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

- `supportedOutputGridSizes` are the supported VkDataGraphOpticalFlowGridSizeFlagsARM which can be specified in `VkDataGraphPipelineOpticalFlowCreateInfoARM`::`outputGridSize`.

- `supportedHintGridSizes` are the supported VkDataGraphOpticalFlowGridSizeFlagsARM which can be specified in `VkDataGraphPipelineOpticalFlowCreateInfoARM`::`hintGridSize`.

- `hintSupported` is a boolean describing whether using hint flow vector map is supported in an optical flow graph pipeline.

- `costSupported` is a boolean describing whether cost map generation is supported in an optical flow graph pipeline.

- `minWidth` is the minimum width in pixels for images used in an optical flow graph pipeline.

- `minHeight` is the minimum height in pixels for images used in an optical flow graph pipeline.

- `maxWidth` is the maximum width in pixels for images used in an optical flow graph pipeline.

- `maxHeight` is the maximum height in pixels for images used in an optical flow graph pipeline.

## Description
