Synopsis

Documentation

createSwapchainKHR :: PokeChain a => Device -> SwapchainCreateInfoKHR a -> ("allocator" ::: Maybe AllocationCallbacks) -> IO SwapchainKHR Source #

vkCreateSwapchainKHR - Create a swapchain

Parameters

  • Device is the device to create the swapchain for.
  • pCreateInfo is a pointer to a SwapchainCreateInfoKHR structure specifying the parameters of the created swapchain.
  • pAllocator is the allocator used for host memory allocated for the swapchain object when there is no more specific allocator available (see Memory Allocation).
  • pSwapchain is a pointer to a SwapchainKHR handle in which the created swapchain object will be returned.

Description

If the oldSwapchain parameter of pCreateInfo is a valid swapchain, which has exclusive full-screen access, that access is released from oldSwapchain. If the command succeeds in this case, the newly created swapchain will automatically acquire exclusive full-screen access from oldSwapchain.

Note

This implicit transfer is intended to avoid exiting and entering full-screen exclusive mode, which may otherwise cause unwanted visual updates to the display.

In some cases, swapchain creation may fail if exclusive full-screen mode is requested for application control, but for some implementation-specific reason exclusive full-screen access is unavailable for the particular combination of parameters provided. If this occurs, ERROR_INITIALIZATION_FAILED will be returned.

Note

In particular, it will fail if the imageExtent member of pCreateInfo does not match the extents of the monitor. Other reasons for failure may include the app not being set as high-dpi aware, or if the physical device and monitor are not compatible in this mode.

Valid Usage (Implicit)

Host Synchronization

  • Host access to pCreateInfo.surface must be externally synchronized
  • Host access to pCreateInfo.oldSwapchain must be externally synchronized

The allocated value must not be returned from the provided computation

destroySwapchainKHR :: Device -> SwapchainKHR -> ("allocator" ::: Maybe AllocationCallbacks) -> IO () Source #

vkDestroySwapchainKHR - Destroy a swapchain object

Parameters

  • swapchain is the swapchain to destroy.
  • pAllocator is the allocator used for host memory allocated for the swapchain object when there is no more specific allocator available (see Memory Allocation).

Description

The application must not destroy a swapchain until after completion of all outstanding operations on images that were acquired from the swapchain. swapchain and all associated Image handles are destroyed, and must not be acquired or used any more by the application. The memory of each Image will only be freed after that image is no longer used by the presentation engine. For example, if one image of the swapchain is being displayed in a window, the memory for that image may not be freed until the window is destroyed, or another swapchain is created for the window. Destroying the swapchain does not invalidate the parent SurfaceKHR, and a new swapchain can be created with it.

When a swapchain associated with a display surface is destroyed, if the image most recently presented to the display surface is from the swapchain being destroyed, then either any display resources modified by presenting images from any swapchain associated with the display surface must be reverted by the implementation to their state prior to the first present performed on one of these swapchains, or such resources must be left in their current state.

If swapchain has exclusive full-screen access, it is released before the swapchain is destroyed.

Valid Usage

  • All uses of presentable images acquired from swapchain must have completed execution
  • If AllocationCallbacks were provided when swapchain was created, a compatible set of callbacks must be provided here
  • If no AllocationCallbacks were provided when swapchain was created, pAllocator must be NULL

Valid Usage (Implicit)

  • If swapchain is not NULL_HANDLE, swapchain must be a valid SwapchainKHR handle
  • If pAllocator is not NULL, pAllocator must be a valid pointer to a valid AllocationCallbacks structure
  • Both of Device, and swapchain that are valid handles of non-ignored parameters must have been created, allocated, or retrieved from the same Instance

Host Synchronization

  • Host access to swapchain must be externally synchronized

getSwapchainImagesKHR :: Device -> SwapchainKHR -> IO (Result, "swapchainImages" ::: Vector Image) Source #

vkGetSwapchainImagesKHR - Obtain the array of presentable images associated with a swapchain

Parameters

  • Device is the device associated with swapchain.
  • swapchain is the swapchain to query.
  • pSwapchainImageCount is a pointer to an integer related to the number of presentable images available or queried, as described below.
  • pSwapchainImages is either NULL or a pointer to an array of Image handles.

Description

If pSwapchainImages is NULL, then the number of presentable images for swapchain is returned in pSwapchainImageCount. Otherwise, pSwapchainImageCount must point to a variable set by the user to the number of elements in the pSwapchainImages array, and on return the variable is overwritten with the number of structures actually written to pSwapchainImages. If the value of pSwapchainImageCount is less than the number of presentable images for swapchain, at most pSwapchainImageCount structures will be written. If pSwapchainImageCount is smaller than the number of presentable images for swapchain, INCOMPLETE will be returned instead of SUCCESS to indicate that not all the available values were returned.

Valid Usage (Implicit)

  • swapchain must be a valid SwapchainKHR handle
  • pSwapchainImageCount must be a valid pointer to a uint32_t value
  • If the value referenced by pSwapchainImageCount is not 0, and pSwapchainImages is not NULL, pSwapchainImages must be a valid pointer to an array of pSwapchainImageCount Image handles
  • Both of Device, and swapchain must have been created, allocated, or retrieved from the same Instance

queuePresentKHR :: PokeChain a => Queue -> PresentInfoKHR a -> IO Result Source #

vkQueuePresentKHR - Queue an image for presentation

Parameters

  • Queue is a queue that is capable of presentation to the target surface’s platform on the same device as the image’s swapchain.
  • pPresentInfo is a pointer to a PresentInfoKHR structure specifying parameters of the presentation.

Description

Note

There is no requirement for an application to present images in the same order that they were acquired - applications can arbitrarily present any image that is currently acquired.

Valid Usage

  • Each element of pSwapchains member of pPresentInfo must be a swapchain that is created for a surface for which presentation is supported from Queue as determined using a call to getPhysicalDeviceSurfaceSupportKHR
  • If more than one member of pSwapchains was created from a display surface, all display surfaces referenced that refer to the same display must use the same display mode
  • When a semaphore wait operation referring to a binary semaphore defined by the elements of the pWaitSemaphores member of pPresentInfo executes on Queue, there must be no other queues waiting on the same semaphore.
  • All elements of the pWaitSemaphores member of pPresentInfo must be semaphores that are signaled, or have semaphore signal operations previously submitted for execution.
  • All elements of the pWaitSemaphores member of pPresentInfo must be created with a SemaphoreType of SEMAPHORE_TYPE_BINARY.
  • All elements of the pWaitSemaphores member of pPresentInfo must reference a semaphore signal operation that has been submitted for execution and any semaphore signal operations on which it depends (if any) must have also been submitted for execution.

Any writes to memory backing the images referenced by the pImageIndices and pSwapchains members of pPresentInfo, that are available before queuePresentKHR is executed, are automatically made visible to the read access performed by the presentation engine. This automatic visibility operation for an image happens-after the semaphore signal operation, and happens-before the presentation engine accesses the image.

Queueing an image for presentation defines a set of queue operations, including waiting on the semaphores and submitting a presentation request to the presentation engine. However, the scope of this set of queue operations does not include the actual processing of the image by the presentation engine.

If queuePresentKHR fails to enqueue the corresponding set of queue operations, it may return ERROR_OUT_OF_HOST_MEMORY or ERROR_OUT_OF_DEVICE_MEMORY. If it does, the implementation must ensure that the state and contents of any resources or synchronization primitives referenced is unaffected by the call or its failure.

If queuePresentKHR fails in such a way that the implementation is unable to make that guarantee, the implementation must return ERROR_DEVICE_LOST.

However, if the presentation request is rejected by the presentation engine with an error ERROR_OUT_OF_DATE_KHR or ERROR_SURFACE_LOST_KHR, the set of queue operations are still considered to be enqueued and thus any semaphore wait operation specified in PresentInfoKHR will execute when the corresponding queue operation is complete.

If any swapchain member of pPresentInfo was created with FULL_SCREEN_EXCLUSIVE_APPLICATION_CONTROLLED_EXT, ERROR_FULL_SCREEN_EXCLUSIVE_MODE_LOST_EXT will be returned if that swapchain does not have exclusive full-screen access, possibly for implementation-specific reasons outside of the application’s control.

Valid Usage (Implicit)

  • pPresentInfo must be a valid pointer to a valid PresentInfoKHR structure

Host Synchronization

  • Host access to Queue must be externally synchronized
  • Host access to pPresentInfo.pWaitSemaphores[] must be externally synchronized
  • Host access to pPresentInfo.pSwapchains[] must be externally synchronized

Parameters

  • surface is the surface.
  • pRectCount is a pointer to an integer related to the number of rectangles available or queried, as described below.
  • pRects is either NULL or a pointer to an array of Rect2D structures.

Description

data SwapchainCreateInfoKHR (es :: [Type]) Source #

VkSwapchainCreateInfoKHR - Structure specifying parameters of a newly created swapchain object

Description

Note

On some platforms, it is normal that maxImageExtent may become (0, 0), for example when the window is minimized. In such a case, it is not possible to create a swapchain due to the Valid Usage requirements.

  • imageArrayLayers is the number of views in a multiview/stereo surface. For non-stereoscopic-3D applications, this value is 1.
  • imageUsage is a bitmask of ImageUsageFlagBits describing the intended usage of the (acquired) swapchain images.
  • imageSharingMode is the sharing mode used for the image(s) of the swapchain.
  • queueFamilyIndexCount is the number of queue families having access to the image(s) of the swapchain when imageSharingMode is SHARING_MODE_CONCURRENT.
  • pQueueFamilyIndices is a pointer to an array of queue family indices having access to the images(s) of the swapchain when imageSharingMode is SHARING_MODE_CONCURRENT.
  • preTransform is a SurfaceTransformFlagBitsKHR value describing the transform, relative to the presentation engine’s natural orientation, applied to the image content prior to presentation. If it does not match the currentTransform value returned by getPhysicalDeviceSurfaceCapabilitiesKHR, the presentation engine will transform the image content as part of the presentation operation.
  • compositeAlpha is a CompositeAlphaFlagBitsKHR value indicating the alpha compositing mode to use when this surface is composited together with other surfaces on certain window systems.
  • presentMode is the presentation mode the swapchain will use. A swapchain’s present mode determines how incoming present requests will be processed and queued internally.
  • clipped specifies whether the Vulkan implementation is allowed to discard rendering operations that affect regions of the surface that are not visible.

    • If set to TRUE, the presentable images associated with the swapchain may not own all of their pixels. Pixels in the presentable images that correspond to regions of the target surface obscured by another window on the desktop, or subject to some other clipping mechanism will have undefined content when read back. Fragment shaders may not execute for these pixels, and thus any side effects they would have had will not occur. TRUE value does not guarantee any clipping will occur, but allows more optimal presentation methods to be used on some platforms.
    • If set to FALSE, presentable images associated with the swapchain will own all of the pixels they contain.

Note

Applications should set this value to TRUE if they do not expect to read back the content of presentable images before presenting them or after reacquiring them, and if their fragment shaders do not have any side effects that require them to run for all pixels in the presentable image.

  • oldSwapchain is NULL_HANDLE, or the existing non-retired swapchain currently associated with surface. Providing a valid oldSwapchain may aid in the resource reuse, and also allows the application to still present any images that are already acquired from it.

Upon calling createSwapchainKHR with an oldSwapchain that is not NULL_HANDLE, oldSwapchain is retired — even if creation of the new swapchain fails. The new swapchain is created in the non-retired state whether or not oldSwapchain is NULL_HANDLE.

Upon calling createSwapchainKHR with an oldSwapchain that is not NULL_HANDLE, any images from oldSwapchain that are not acquired by the application may be freed by the implementation, which may occur even if creation of the new swapchain fails. The application can destroy oldSwapchain to free all memory associated with oldSwapchain.

Note

Multiple retired swapchains can be associated with the same SurfaceKHR through multiple uses of oldSwapchain that outnumber calls to destroySwapchainKHR.

After oldSwapchain is retired, the application can pass to queuePresentKHR any images it had already acquired from oldSwapchain. E.g., an application may present an image from the old swapchain before an image from the new swapchain is ready to be presented. As usual, queuePresentKHR may fail if oldSwapchain has entered a state that causes ERROR_OUT_OF_DATE_KHR to be returned.

The application can continue to use a shared presentable image obtained from oldSwapchain until a presentable image is acquired from the new swapchain, as long as it has not entered a state that causes it to return ERROR_OUT_OF_DATE_KHR.

VkPresentInfoKHR - Structure describing parameters of a queue presentation

Description

Before an application can present an image, the image’s layout must be transitioned to the IMAGE_LAYOUT_PRESENT_SRC_KHR layout, or for a shared presentable image the IMAGE_LAYOUT_SHARED_PRESENT_KHR layout.

Note

When transitioning the image to IMAGE_LAYOUT_SHARED_PRESENT_KHR or IMAGE_LAYOUT_PRESENT_SRC_KHR, there is no need to delay subsequent processing, or perform any visibility operations (as queuePresentKHR performs automatic visibility operations). To achieve this, the dstAccessMask member of the ImageMemoryBarrier should be set to 0, and the dstStageMask parameter should be set to PIPELINE_STAGE_BOTTOM_OF_PIPE_BIT.

Valid Usage

  • Each element of pImageIndices must be the index of a presentable image acquired from the swapchain specified by the corresponding element of the pSwapchains array, and the presented image subresource must be in the IMAGE_LAYOUT_PRESENT_SRC_KHR or IMAGE_LAYOUT_SHARED_PRESENT_KHR layout at the time the operation is executed on a Device

Valid Usage (Implicit)

  • Each pNext member of any structure (including this one) in the pNext chain must be either NULL or a pointer to a valid instance of DeviceGroupPresentInfoKHR, DisplayPresentInfoKHR, PresentFrameTokenGGP, PresentRegionsKHR, or PresentTimesInfoGOOGLE
  • The sType value of each struct in the pNext chain must be unique
  • If waitSemaphoreCount is not 0, pWaitSemaphores must be a valid pointer to an array of waitSemaphoreCount valid Semaphore handles
  • pSwapchains must be a valid pointer to an array of swapchainCount valid SwapchainKHR handles
  • pImageIndices must be a valid pointer to an array of swapchainCount uint32_t values
  • If pResults is not NULL, pResults must be a valid pointer to an array of swapchainCount Result values
  • swapchainCount must be greater than 0
  • Both of the elements of pSwapchains, and the elements of pWaitSemaphores that are valid handles of non-ignored parameters must have been created, allocated, or retrieved from the same Instance

  • waitSemaphores :: Vector Semaphore

    pWaitSemaphores is NULL or a pointer to an array of Semaphore objects with waitSemaphoreCount entries, and specifies the semaphores to wait for before issuing the present request.

  • swapchains :: Vector SwapchainKHR

    pSwapchains is a pointer to an array of SwapchainKHR objects with swapchainCount entries. A given swapchain must not appear in this list more than once.

  • imageIndices :: Vector Word32

    pImageIndices is a pointer to an array of indices into the array of each swapchain’s presentable images, with swapchainCount entries. Each entry in this array identifies the image to present on the corresponding entry in the pSwapchains array.

  • results :: Ptr Result

    pResults is a pointer to an array of Result typed elements with swapchainCount entries. Applications that do not need per-swapchain results can use NULL for pResults. If non-NULL, each entry in pResults will be set to the Result for presenting the swapchain corresponding to the same index in pSwapchains.

VkAcquireNextImageInfoKHR - Structure specifying parameters of the acquire

Description

If acquireNextImageKHR is used, the device mask is considered to include all physical devices in the logical device.

Note

acquireNextImage2KHR signals at most one semaphore, even if the application requests waiting for multiple physical devices to be ready via the deviceMask. However, only a single physical device can wait on that semaphore, since the semaphore becomes unsignaled when the wait succeeds. For other physical devices to wait for the image to be ready, it is necessary for the application to submit semaphore signal operation(s) to that first physical device to signal additional semaphore(s) after the wait succeeds, which the other physical device(s) can wait upon.

  • swapchain must not be in the retired state

VkDeviceGroupPresentInfoKHR - Mode and mask controlling which physical devices' images are presented

Description

If mode is DEVICE_GROUP_PRESENT_MODE_LOCAL_BIT_KHR, then each element of pDeviceMasks selects which instance of the swapchain image is presented. Each element of pDeviceMasks must have exactly one bit set, and the corresponding physical device must have a presentation engine as reported by DeviceGroupPresentCapabilitiesKHR.

If mode is DEVICE_GROUP_PRESENT_MODE_REMOTE_BIT_KHR, then each element of pDeviceMasks selects which instance of the swapchain image is presented. Each element of pDeviceMasks must have exactly one bit set, and some physical device in the logical device must include that bit in its DeviceGroupPresentCapabilitiesKHR::presentMask.

If mode is DEVICE_GROUP_PRESENT_MODE_SUM_BIT_KHR, then each element of pDeviceMasks selects which instances of the swapchain image are component-wise summed and the sum of those images is presented. If the sum in any component is outside the representable range, the value of that component is undefined. Each element of pDeviceMasks must have a value for which all set bits are set in one of the elements of DeviceGroupPresentCapabilitiesKHR::presentMask.

If mode is DEVICE_GROUP_PRESENT_MODE_LOCAL_MULTI_DEVICE_BIT_KHR, then each element of pDeviceMasks selects which instance(s) of the swapchain images are presented. For each bit set in each element of pDeviceMasks, the corresponding physical device must have a presentation engine as reported by DeviceGroupPresentCapabilitiesKHR.

If DeviceGroupPresentInfoKHR is not provided or swapchainCount is zero then the masks are considered to be 1. If DeviceGroupPresentInfoKHR is not provided, mode is considered to be DEVICE_GROUP_PRESENT_MODE_LOCAL_BIT_KHR.

Valid Usage

Valid Usage (Implicit)

  • If swapchainCount is not 0, pDeviceMasks must be a valid pointer to an array of swapchainCount uint32_t values

VkSwapchainKHR - Opaque handle to a swapchain object

Description

A swapchain is an abstraction for an array of presentable images that are associated with a surface. The presentable images are represented by Image objects created by the platform. One image (which can be an array image for multiview/stereoscopic-3D surfaces) is displayed at a time, but multiple images can be queued for presentation. An application renders to the image, and then queues the image for presentation to the surface.

A native window cannot be associated with more than one non-retired swapchain at a time. Further, swapchains cannot be created for native windows that have a non-Vulkan graphics API surface associated with them.

Note

The presentation engine is an abstraction for the platform’s compositor or display engine.

The presentation engine may be synchronous or asynchronous with respect to the application and/or logical device.

Some implementations may use the device’s graphics queue or dedicated presentation hardware to perform presentation.

The presentable images of a swapchain are owned by the presentation engine. An application can acquire use of a presentable image from the presentation engine. Use of a presentable image must occur only after the image is returned by acquireNextImageKHR, and before it is presented by queuePresentKHR. This includes transitioning the image layout and rendering commands.

An application can acquire use of a presentable image with acquireNextImageKHR. After acquiring a presentable image and before modifying it, the application must use a synchronization primitive to ensure that the presentation engine has finished reading from the image. The application can then transition the image’s layout, queue rendering commands to it, etc. Finally, the application presents the image with queuePresentKHR, which releases the acquisition of the image.

The presentation engine controls the order in which presentable images are acquired for use by the application.

Note

This allows the platform to handle situations which require out-of-order return of images after presentation. At the same time, it allows the application to generate command buffers referencing all of the images in the swapchain at initialization time, rather than in its main loop.

VkPresentModeKHR - presentation mode supported for a surface

Description

The supported ImageUsageFlagBits of the presentable images of a swapchain created for a surface may differ depending on the presentation mode, and can be determined as per the table below:

Presentation mode Image usage flags
PRESENT_MODE_IMMEDIATE_KHR SurfaceCapabilitiesKHR::supportedUsageFlags
PRESENT_MODE_MAILBOX_KHR SurfaceCapabilitiesKHR::supportedUsageFlags
PRESENT_MODE_FIFO_KHR SurfaceCapabilitiesKHR::supportedUsageFlags
PRESENT_MODE_FIFO_RELAXED_KHR SurfaceCapabilitiesKHR::supportedUsageFlags
PRESENT_MODE_SHARED_DEMAND_REFRESH_KHR SharedPresentSurfaceCapabilitiesKHR::sharedPresentSupportedUsageFlags
PRESENT_MODE_SHARED_CONTINUOUS_REFRESH_KHR SharedPresentSurfaceCapabilitiesKHR::sharedPresentSupportedUsageFlags

Presentable image usage queries

Note

For reference, the mode indicated by PRESENT_MODE_FIFO_KHR is equivalent to the behavior of {wgl|glX|egl}SwapBuffers with a swap interval of 1, while the mode indicated by PRESENT_MODE_FIFO_RELAXED_KHR is equivalent to the behavior of {wgl|glX}SwapBuffers with a swap interval of -1 (from the {WGL|GLX}_EXT_swap_control_tear extensions).

Bundled Patterns

pattern PRESENT_MODE_IMMEDIATE_KHR :: PresentModeKHR

PRESENT_MODE_IMMEDIATE_KHR specifies that the presentation engine does not wait for a vertical blanking period to update the current image, meaning this mode may result in visible tearing. No internal queuing of presentation requests is needed, as the requests are applied immediately.

pattern PRESENT_MODE_MAILBOX_KHR :: PresentModeKHR

PRESENT_MODE_MAILBOX_KHR specifies that the presentation engine waits for the next vertical blanking period to update the current image. Tearing cannot be observed. An internal single-entry queue is used to hold pending presentation requests. If the queue is full when a new presentation request is received, the new request replaces the existing entry, and any images associated with the prior entry become available for re-use by the application. One request is removed from the queue and processed during each vertical blanking period in which the queue is non-empty.

pattern PRESENT_MODE_FIFO_KHR :: PresentModeKHR

PRESENT_MODE_FIFO_KHR specifies that the presentation engine waits for the next vertical blanking period to update the current image. Tearing cannot be observed. An internal queue is used to hold pending presentation requests. New requests are appended to the end of the queue, and one request is removed from the beginning of the queue and processed during each vertical blanking period in which the queue is non-empty. This is the only value of presentMode that is required to be supported.

pattern PRESENT_MODE_FIFO_RELAXED_KHR :: PresentModeKHR

PRESENT_MODE_FIFO_RELAXED_KHR specifies that the presentation engine generally waits for the next vertical blanking period to update the current image. If a vertical blanking period has already passed since the last update of the current image then the presentation engine does not wait for another vertical blanking period for the update, meaning this mode may result in visible tearing in this case. This mode is useful for reducing visual stutter with an application that will mostly present a new image before the next vertical blanking period, but may occasionally be late, and present a new image just after the next vertical blanking period. An internal queue is used to hold pending presentation requests. New requests are appended to the end of the queue, and one request is removed from the beginning of the queue and processed during or after each vertical blanking period in which the queue is non-empty.

pattern PRESENT_MODE_SHARED_CONTINUOUS_REFRESH_KHR :: PresentModeKHR

PRESENT_MODE_SHARED_CONTINUOUS_REFRESH_KHR specifies that the presentation engine and application have concurrent access to a single image, which is referred to as a shared presentable image. The presentation engine periodically updates the current image on its regular refresh cycle. The application is only required to make one initial presentation request, after which the presentation engine must update the current image without any need for further presentation requests. The application can indicate the image contents have been updated by making a presentation request, but this does not guarantee the timing of when it will be updated. This mode may result in visible tearing if rendering to the image is not timed correctly.

pattern PRESENT_MODE_SHARED_DEMAND_REFRESH_KHR :: PresentModeKHR

PRESENT_MODE_SHARED_DEMAND_REFRESH_KHR specifies that the presentation engine and application have concurrent access to a single image, which is referred to as a shared presentable image. The presentation engine is only required to update the current image after a new presentation request is received. Therefore the application must make a presentation request whenever an update is required. However, the presentation engine may update the current image at any point, meaning this mode may result in visible tearing.

VkColorSpaceKHR - supported color space of the presentation engine

Description

Note

In the initial release of the VK_KHR_surface and https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#VK_KHR_swapchain extensions, the token VK_COLORSPACE_SRGB_NONLINEAR_KHR was used. Starting in the 2016-05-13 updates to the extension branches, matching release 1.0.13 of the core API specification, COLOR_SPACE_SRGB_NONLINEAR_KHR is used instead for consistency with Vulkan naming rules. The older enum is still available for backwards compatibility.

Note

In older versions of this extension COLOR_SPACE_DISPLAY_P3_LINEAR_EXT was misnamed COLOR_SPACE_DCI_P3_LINEAR_EXT. This has been updated to indicate that it uses RGB color encoding, not XYZ. The old name is deprecated but is maintained for backwards compatibility.

The color components of non-linear color space swap chain images must have had the appropriate transfer function applied. The color space selected for the swap chain image will not affect the processing of data written into the image by the implementation. Vulkan requires that all implementations support the sRGB transfer function by use of an SRGB pixel format. Other transfer functions, such as SMPTE 170M or SMPTE2084, can be performed by the application shader. This extension defines enums for ColorSpaceKHR that correspond to the following color spaces:

Name Red Primary Green Primary Blue Primary White-point Transfer function

AdobeRGB 0.640, 0.330 0.210, 0.710 0.150, 0.060 0.3127, 0.3290 (D65) AdobeRGB

Bundled Patterns

pattern COMPOSITE_ALPHA_OPAQUE_BIT_KHR :: CompositeAlphaFlagBitsKHR

COMPOSITE_ALPHA_OPAQUE_BIT_KHR: The alpha channel, 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.

pattern COMPOSITE_ALPHA_PRE_MULTIPLIED_BIT_KHR :: CompositeAlphaFlagBitsKHR

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

pattern COMPOSITE_ALPHA_POST_MULTIPLIED_BIT_KHR :: CompositeAlphaFlagBitsKHR

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

pattern COMPOSITE_ALPHA_INHERIT_BIT_KHR :: CompositeAlphaFlagBitsKHR

COMPOSITE_ALPHA_INHERIT_BIT_KHR: The way in which the presentation engine treats the alpha channel 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.
