# VkSurfaceTransformFlagBitsKHR(3) Manual Page

## Name

VkSurfaceTransformFlagBitsKHR - Presentation transforms supported on a device

Loading… please wait.

## C Specification

Bits which may be set in VkSurfaceCapabilitiesKHR::`supportedTransforms` indicating the presentation transforms supported for the surface on the specified device, and possible values of VkSurfaceCapabilitiesKHR::`currentTransform` indicating the surface’s current transform relative to the presentation engine’s natural orientation, are:

    // Provided by VK_KHR_surface
    typedef enum VkSurfaceTransformFlagBitsKHR {
        VK_SURFACE_TRANSFORM_IDENTITY_BIT_KHR = 0x00000001,
        VK_SURFACE_TRANSFORM_ROTATE_90_BIT_KHR = 0x00000002,
        VK_SURFACE_TRANSFORM_ROTATE_180_BIT_KHR = 0x00000004,
        VK_SURFACE_TRANSFORM_ROTATE_270_BIT_KHR = 0x00000008,
        VK_SURFACE_TRANSFORM_HORIZONTAL_MIRROR_BIT_KHR = 0x00000010,
        VK_SURFACE_TRANSFORM_HORIZONTAL_MIRROR_ROTATE_90_BIT_KHR = 0x00000020,
        VK_SURFACE_TRANSFORM_HORIZONTAL_MIRROR_ROTATE_180_BIT_KHR = 0x00000040,
        VK_SURFACE_TRANSFORM_HORIZONTAL_MIRROR_ROTATE_270_BIT_KHR = 0x00000080,
        VK_SURFACE_TRANSFORM_INHERIT_BIT_KHR = 0x00000100,
    } VkSurfaceTransformFlagBitsKHR;

## Description

- `VK_SURFACE_TRANSFORM_IDENTITY_BIT_KHR` specifies that image content is presented without being transformed.

- `VK_SURFACE_TRANSFORM_ROTATE_90_BIT_KHR` specifies that image content is rotated 90 degrees clockwise.

- `VK_SURFACE_TRANSFORM_ROTATE_180_BIT_KHR` specifies that image content is rotated 180 degrees clockwise.

- `VK_SURFACE_TRANSFORM_ROTATE_270_BIT_KHR` specifies that image content is rotated 270 degrees clockwise.

- `VK_SURFACE_TRANSFORM_HORIZONTAL_MIRROR_BIT_KHR` specifies that image content is mirrored horizontally.

- `VK_SURFACE_TRANSFORM_HORIZONTAL_MIRROR_ROTATE_90_BIT_KHR` specifies that image content is mirrored horizontally, then rotated 90 degrees clockwise.

- `VK_SURFACE_TRANSFORM_HORIZONTAL_MIRROR_ROTATE_180_BIT_KHR` specifies that image content is mirrored horizontally, then rotated 180 degrees clockwise.

- `VK_SURFACE_TRANSFORM_HORIZONTAL_MIRROR_ROTATE_270_BIT_KHR` specifies that image content is mirrored horizontally, then rotated 270 degrees clockwise.

- `VK_SURFACE_TRANSFORM_INHERIT_BIT_KHR` specifies that the presentation transform is not specified, and is instead determined by platform-specific considerations and mechanisms outside Vulkan.
