# VkDataGraphOpticalFlowImageUsageFlagBitsARM(3) Manual Page

## Name

VkDataGraphOpticalFlowImageUsageFlagBitsARM - Bits specifying image usage for optical flow operations

## C Specification

Bits which can be set in VkDataGraphOpticalFlowImageFormatInfoARM::`usage`, controlling optical flow usage, are:

    // Provided by VK_ARM_data_graph_optical_flow
    typedef enum VkDataGraphOpticalFlowImageUsageFlagBitsARM {
        VK_DATA_GRAPH_OPTICAL_FLOW_IMAGE_USAGE_UNKNOWN_ARM = 0,
        VK_DATA_GRAPH_OPTICAL_FLOW_IMAGE_USAGE_INPUT_BIT_ARM = 0x00000001,
        VK_DATA_GRAPH_OPTICAL_FLOW_IMAGE_USAGE_OUTPUT_BIT_ARM = 0x00000002,
        VK_DATA_GRAPH_OPTICAL_FLOW_IMAGE_USAGE_HINT_BIT_ARM = 0x00000004,
        VK_DATA_GRAPH_OPTICAL_FLOW_IMAGE_USAGE_COST_BIT_ARM = 0x00000008,
    } VkDataGraphOpticalFlowImageUsageFlagBitsARM;

## Description

- VK_DATA_GRAPH_OPTICAL_FLOW_IMAGE_USAGE_INPUT_BIT_ARM specifies that the image can be used as input or reference image for an optical flow operation.

- VK_DATA_GRAPH_OPTICAL_FLOW_IMAGE_USAGE_OUTPUT_BIT_ARM specifies that the image can be used as output flow vector map for an optical flow operation.

- VK_DATA_GRAPH_OPTICAL_FLOW_IMAGE_USAGE_HINT_BIT_ARM specifies that the image can be used as hint flow vector map for an optical flow operation.

- VK_DATA_GRAPH_OPTICAL_FLOW_IMAGE_USAGE_COST_BIT_ARM specifies that the image can be used as output cost map for an optical flow operation.
