pattern VK_DISPLAY_PLANE_ALPHA_OPAQUE_BIT_KHR :: VkDisplayPlaneAlphaFlagBitsKHR Source #

VK_DISPLAY_PLANE_ALPHA_OPAQUE_BIT_KHR specifies that the source image will be treated as opaque.

pattern VK_DISPLAY_PLANE_ALPHA_GLOBAL_BIT_KHR :: VkDisplayPlaneAlphaFlagBitsKHR Source #

VK_DISPLAY_PLANE_ALPHA_GLOBAL_BIT_KHR specifies that a global alpha value must be specified that will be applied to all pixels in the source image.

pattern VK_DISPLAY_PLANE_ALPHA_PER_PIXEL_BIT_KHR :: VkDisplayPlaneAlphaFlagBitsKHR Source #

VK_DISPLAY_PLANE_ALPHA_PER_PIXEL_BIT_KHR specifies that the alpha value will be determined by the alpha channel of the source image’s pixels. If the source format contains no alpha values, no blending will be applied. The source alpha values are not premultiplied into the source image’s other color channels.

pattern VK_DISPLAY_PLANE_ALPHA_PER_PIXEL_PREMULTIPLIED_BIT_KHR :: VkDisplayPlaneAlphaFlagBitsKHR Source #

VK_DISPLAY_PLANE_ALPHA_PER_PIXEL_PREMULTIPLIED_BIT_KHR is equivalent to VK_DISPLAY_PLANE_ALPHA_PER_PIXEL_BIT_KHR, except the source alpha values are assumed to be premultiplied into the source image’s other color channels.

vkGetPhysicalDeviceDisplayPropertiesKHR :: ("physicalDevice" ::: VkPhysicalDevice) -> ("pPropertyCount" ::: Ptr Word32) -> ("pProperties" ::: Ptr VkDisplayPropertiesKHR) -> IO VkResult Source #

vkGetPhysicalDeviceDisplayPropertiesKHR - Query information about the available displays

Parameters

  • physicalDevice is a physical device.
  • pPropertyCount is a pointer to an integer related to the number of display devices available or queried, as described below.
  • pProperties is either NULL or a pointer to an array of VkDisplayPropertiesKHR structures.

Description

If pProperties is NULL, then the number of display devices available for physicalDevice is returned in pPropertyCount. Otherwise, pPropertyCount must point to a variable set by the user to the number of elements in the pProperties array, and on return the variable is overwritten with the number of structures actually written to pProperties. If the value of pPropertyCount is less than the number of display devices for physicalDevice, at most pPropertyCount structures will be written. If pPropertyCount is smaller than the number of display devices available for physicalDevice, VK_INCOMPLETE will be returned instead of VK_SUCCESS to indicate that not all the available values were returned.

Valid Usage (Implicit)

  • physicalDevice must be a valid VkPhysicalDevice handle
  • pPropertyCount must be a valid pointer to a uint32_t value
  • If the value referenced by pPropertyCount is not 0, and pProperties is not NULL, pProperties must be a valid pointer to an array of pPropertyCount VkDisplayPropertiesKHR structures

Return Codes

[Success] - VK_SUCCESS

  • VK_INCOMPLETE

[Failure] - VK_ERROR_OUT_OF_HOST_MEMORY

  • VK_ERROR_OUT_OF_DEVICE_MEMORY

vkGetDisplayPlaneSupportedDisplaysKHR - Query the list of displays a plane supports

Parameters

If the value of pDisplayCount is less than the number of display planes for physicalDevice, at most pDisplayCount handles will be written. If pDisplayCount is smaller than the number of displays usable with the specified planeIndex for physicalDevice, VK_INCOMPLETE will be returned instead of VK_SUCCESS to indicate that not all the available values were returned.

data VkDisplayPropertiesKHR Source #

VkDisplayPropertiesKHR - Structure describing an available display device

Description

Note

For devices which have no natural value to return here, implementations should return the maximum resolution supported.

  • supportedTransforms tells which transforms are supported by this display. This will contain one or more of the bits from VkSurfaceTransformFlagsKHR.
  • planeReorderPossible tells whether the planes on this display can have their z order changed. If this is VK_TRUE, the application can re-arrange the planes on this display in any order relative to each other.
  • persistentContent tells whether the display supports self-refresh/internal buffering. If this is true, the application can submit persistent present operations on swapchains created against this display.

Note

Persistent presents may have higher latency, and may use less power when the screen content is updated infrequently, or when only a portion of the screen needs to be updated in most frames.

data VkDisplayPlaneCapabilitiesKHR Source #

VkDisplayPlaneCapabilitiesKHR - Structure describing capabilities of a mode and plane combination

Description

The minimum and maximum position and extent fields describe the implementation limits, if any, as they apply to the specified display mode and plane. Vendors may support displaying a subset of a swapchain’s presentable images on the specified display plane. This is expressed by returning minSrcPosition, maxSrcPosition, minSrcExtent, and maxSrcExtent values that indicate a range of possible positions and sizes may be used to specify the region within the presentable images that source pixels will be read from when creating a swapchain on the specified display mode and plane.

Vendors may also support mapping the presentable images’ content to a subset or superset of the visible region in the specified display mode. This is expressed by returning minDstPosition, maxDstPosition, minDstExtent and maxDstExtent values that indicate a range of possible positions and sizes may be used to describe the region within the display mode that the source pixels will be mapped to.

Other vendors may support only a 1-1 mapping between pixels in the presentable images and the display mode. This may be indicated by returning (0,0) for minSrcPosition, maxSrcPosition, minDstPosition, and maxDstPosition, and (display mode width, display mode height) for minSrcExtent, maxSrcExtent, minDstExtent, and maxDstExtent.

These values indicate the limits of the implementation’s individual fields. Not all combinations of values within the offset and extent ranges returned in VkDisplayPlaneCapabilitiesKHR are guaranteed to be supported. Vendors may still fail presentation requests that specify unsupported combinations.

Fields

data VkDisplaySurfaceCreateInfoKHR Source #

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

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

  • planeIndex must be less than the number of display planes supported by the device as determined by calling vkGetPhysicalDeviceDisplayPlanePropertiesKHR
  • 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
  • If alphaMode is VK_DISPLAY_PLANE_ALPHA_GLOBAL_BIT_KHR then globalAlpha must be between 0 and 1, inclusive
  • alphaMode must be 0 or one of the bits present in the supportedAlpha member of VkDisplayPlaneCapabilitiesKHR returned by vkGetDisplayPlaneCapabilitiesKHR for the display plane corresponding to displayMode
  • The width and height members of imageExtent must be less than the maxImageDimensions2D member of VkPhysicalDeviceLimits

Valid Usage (Implicit)

  • sType must be VK_STRUCTURE_TYPE_DISPLAY_SURFACE_CREATE_INFO_KHR
