vkGetPhysicalDeviceSurfaceCapabilities2EXT - Query surface capabilities

Description

getPhysicalDeviceSurfaceCapabilities2EXT behaves similarly to getPhysicalDeviceSurfaceCapabilitiesKHR, with the ability to return extended information by adding extending structures to the pNext chain of its pSurfaceCapabilities parameter.

Valid Usage

• surface must be supported by physicalDevice, as reported by getPhysicalDeviceSurfaceSupportKHR or an equivalent platform-specific mechanism

Valid Usage (Implicit)

• physicalDevice must be a valid PhysicalDevice handle

• surface must be a valid SurfaceKHR handle

• pSurfaceCapabilities must be a valid pointer to a SurfaceCapabilities2EXT structure

• Both of physicalDevice, and surface must have been created, allocated, or retrieved from the same Instance

Return Codes

Success

• SUCCESS

Failure

• ERROR_OUT_OF_DEVICE_MEMORY

• ERROR_OUT_OF_HOST_MEMORY

• ERROR_SURFACE_LOST_KHR

• ERROR_UNKNOWN

• ERROR_VALIDATION_FAILED

VkSurfaceCounterFlagBitsEXT - Surface-relative counter types

Description

• SURFACE_COUNTER_VBLANK_BIT_EXT specifies a counter incrementing once every time a vertical blanking period occurs on the display associated with the surface.

VkSurfaceKHR - Opaque handle to a surface object

Description

The VK_KHR_surface extension declares the SurfaceKHR object, and provides a function for destroying SurfaceKHR objects. Separate platform-specific extensions each provide a function for creating a SurfaceKHR object for the respective platform. From the application’s perspective this is an opaque handle, just like the handles of other Vulkan objects.

VkCompositeAlphaFlagBitsKHR - Alpha compositing modes supported on a device

Description

These values are described as follows:

• COMPOSITE_ALPHA_OPAQUE_BIT_KHR: The alpha component, if it exists, of the images is ignored in the compositing process. Instead, the image is treated as if it has a constant alpha of 1.0.

• COMPOSITE_ALPHA_PRE_MULTIPLIED_BIT_KHR: The alpha component, if it exists, of the images is respected in the compositing process. The non-alpha components of the image are expected to already be multiplied by the alpha component by the application.

• COMPOSITE_ALPHA_POST_MULTIPLIED_BIT_KHR: The alpha component, if it exists, of the images is respected in the compositing process. The non-alpha components of the image are not expected to already be multiplied by the alpha component by the application; instead, the compositor will multiply the non-alpha components of the image by the alpha component during compositing.

• COMPOSITE_ALPHA_INHERIT_BIT_KHR: The way in which the presentation engine treats the alpha component in the images is unknown to the Vulkan API. Instead, the application is responsible for setting the composite alpha blending mode using native window system commands. If the application does not set the blending mode using native window system commands, then a platform-specific default will be used.

VkSurfaceTransformFlagBitsKHR - Presentation transforms supported on a device

Description

• SURFACE_TRANSFORM_IDENTITY_BIT_KHR specifies that image content is presented without being transformed.

• SURFACE_TRANSFORM_ROTATE_90_BIT_KHR specifies that image content is rotated 90 degrees clockwise.

• SURFACE_TRANSFORM_ROTATE_180_BIT_KHR specifies that image content is rotated 180 degrees clockwise.

• SURFACE_TRANSFORM_ROTATE_270_BIT_KHR specifies that image content is rotated 270 degrees clockwise.

• SURFACE_TRANSFORM_HORIZONTAL_MIRROR_BIT_KHR specifies that image content is mirrored horizontally.

• SURFACE_TRANSFORM_HORIZONTAL_MIRROR_ROTATE_90_BIT_KHR specifies that image content is mirrored horizontally, then rotated 90 degrees clockwise.

• SURFACE_TRANSFORM_HORIZONTAL_MIRROR_ROTATE_180_BIT_KHR specifies that image content is mirrored horizontally, then rotated 180 degrees clockwise.

• SURFACE_TRANSFORM_HORIZONTAL_MIRROR_ROTATE_270_BIT_KHR specifies that image content is mirrored horizontally, then rotated 270 degrees clockwise.

• 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.
