## Name

VkDisplaySurfaceCreateInfoKHR - Structure specifying parameters of a newly created display plane surface object

Loading… please wait.

## C Specification

The `VkDisplaySurfaceCreateInfoKHR` structure is defined as:

    // Provided by VK_KHR_display
    typedef struct VkDisplaySurfaceCreateInfoKHR {
        VkStructureType                   sType;
        const void*                       pNext;
        VkDisplaySurfaceCreateFlagsKHR    flags;
        VkDisplayModeKHR                  displayMode;
        uint32_t                          planeIndex;
        uint32_t                          planeStackIndex;
        VkSurfaceTransformFlagBitsKHR     transform;
        float                             globalAlpha;
        VkDisplayPlaneAlphaFlagBitsKHR    alphaMode;
        VkExtent2D                        imageExtent;
    } VkDisplaySurfaceCreateInfoKHR;

## Members

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

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

- `flags` is reserved for future use, and must be zero.

- `displayMode` is a VkDisplayModeKHR handle specifying the mode to use when displaying this surface.

- `planeIndex` is the plane on which this surface appears.

- `planeStackIndex` is the z-order of the plane.

- `transform` is a VkSurfaceTransformFlagBitsKHR value specifying the transformation to apply to images as part of the scanout operation.

- `globalAlpha` is the global alpha value. This value is ignored if `alphaMode` is not `VK_DISPLAY_PLANE_ALPHA_GLOBAL_BIT_KHR`.

- `alphaMode` is a VkDisplayPlaneAlphaFlagBitsKHR value specifying the type of alpha blending to use.

- `imageExtent` is the size of the presentable images to use with the surface.

## Description

Note | Creating a display surface must not modify the state of the displays, planes, or other resources it names. For example, it must not apply the specified mode to be set on the associated display. Application of display configuration occurs as a side effect of presenting to a display surface.

Valid Usage

- VUID-VkDisplaySurfaceCreateInfoKHR-planeIndex-01252
  `planeIndex` must be less than the number of display planes supported by the device as determined by calling `vkGetPhysicalDeviceDisplayPlanePropertiesKHR`

- VUID-VkDisplaySurfaceCreateInfoKHR-planeReorderPossible-01253
  If the `planeReorderPossible` member of the `VkDisplayPropertiesKHR` structure returned by `vkGetPhysicalDeviceDisplayPropertiesKHR` for the display corresponding to `displayMode` is `VK_TRUE` then `planeStackIndex` must be less than the number of display planes supported by the device as determined by calling `vkGetPhysicalDeviceDisplayPlanePropertiesKHR`; otherwise `planeStackIndex` must equal the `currentStackIndex` member of `VkDisplayPlanePropertiesKHR` returned by `vkGetPhysicalDeviceDisplayPlanePropertiesKHR` for the display plane corresponding to `displayMode`

- VUID-VkDisplaySurfaceCreateInfoKHR-alphaMode-01254
  If `alphaMode` is `VK_DISPLAY_PLANE_ALPHA_GLOBAL_BIT_KHR` then `globalAlpha` must be between `0` and `1`, inclusive

- VUID-VkDisplaySurfaceCreateInfoKHR-alphaMode-01255
  `alphaMode` must be one of the bits present in the `supportedAlpha` member of `VkDisplayPlaneCapabilitiesKHR` for the display plane corresponding to `displayMode`

- VUID-VkDisplaySurfaceCreateInfoKHR-transform-06740
  `transform` must be one of the bits present in the `supportedTransforms` member of `VkDisplayPropertiesKHR` for the display corresponding to `displayMode`

- VUID-VkDisplaySurfaceCreateInfoKHR-width-01256
  The `width` and `height` members of `imageExtent` must be less than or equal to VkPhysicalDeviceLimits::`maxImageDimension2D`

- VUID-VkDisplaySurfaceCreateInfoKHR-pNext-10284
  If the `pNext` chain includes a VkDisplaySurfaceStereoCreateInfoNV structure whose `stereoType` member is `VK_DISPLAY_SURFACE_STEREO_TYPE_HDMI_3D_NV`, then the `hdmi3DSupported` member of the VkDisplayModeStereoPropertiesNV structure in the `pNext` chain of the `VkDisplayModeProperties2KHR` structure returned by vkGetDisplayModeProperties2KHR for the display mode corresponding to `displayMode` must be `VK_TRUE`

Valid Usage (Implicit)

- VUID-VkDisplaySurfaceCreateInfoKHR-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_DISPLAY_SURFACE_CREATE_INFO_KHR`

- VUID-VkDisplaySurfaceCreateInfoKHR-pNext-pNext
  `pNext` must be `NULL` or a pointer to a valid instance of VkDisplaySurfaceStereoCreateInfoNV

- VUID-VkDisplaySurfaceCreateInfoKHR-sType-unique
  The `sType` value of each struct in the `pNext` chain must be unique

- VUID-VkDisplaySurfaceCreateInfoKHR-flags-zerobitmask
  `flags` must be `0`

- VUID-VkDisplaySurfaceCreateInfoKHR-displayMode-parameter
  `displayMode` must be a valid VkDisplayModeKHR handle

- VUID-VkDisplaySurfaceCreateInfoKHR-transform-parameter
  `transform` must be a valid VkSurfaceTransformFlagBitsKHR value

- VUID-VkDisplaySurfaceCreateInfoKHR-alphaMode-parameter
  `alphaMode` must be a valid VkDisplayPlaneAlphaFlagBitsKHR value
