VkPresentRegionsKHR - Structure hint of rectangular regions changed by vkQueuePresentKHR

Valid Usage

swapchainCount must be the same value as VkPresentInfoKHR::swapchainCount, where VkPresentInfoKHR is in the pNext-chain of this VkPresentRegionsKHR structure.

Valid Usage (Implicit)

sType must be VK_STRUCTURE_TYPE_PRESENT_REGIONS_KHR

If pRegions is not NULL, pRegions must be a valid pointer to an array of swapchainCount valid VkPresentRegionKHR structures
swapchainCount must be greater than 0

vkSType :: VkStructureType
sType is the type of this structure.
vkPNext :: Ptr ()
pNext is NULL or a pointer to an extension-specific structure.
vkSwapchainCount :: Word32
swapchainCount is the number of swapchains being presented to by this command.
vkPRegions :: Ptr VkPresentRegionKHR
pRegions is NULL or a pointer to an array of VkPresentRegionKHR elements with swapchainCount entries. If not NULL, each element of pRegions contains the region that has changed since the last present to the swapchain in the corresponding entry in the VkPresentInfoKHR::pSwapchains array.

data VkPresentRegionKHR Source #

VkPresentRegionKHR - Structure containing rectangular region changed by vkQueuePresentKHR for a given VkImage

Valid Usage (Implicit)

If rectangleCount is not 0, and pRectangles is not NULL, pRectangles must be a valid pointer to an array of rectangleCount VkRectLayerKHR structures

vkRectangleCount :: Word32
rectangleCount is the number of rectangles in pRectangles, or zero if the entire image has changed and should be presented.
vkPRectangles :: Ptr VkRectLayerKHR
pRectangles is either NULL or a pointer to an array of VkRectLayerKHR structures. The VkRectLayerKHR structure is the framebuffer coordinates, plus layer, of a portion of a presentable image that has changed and must be presented. If non-NULL, each entry in pRectangles is a rectangle of the given image that has changed since the last image was presented to the given swapchain.

VkRectLayerKHR - Structure containing a rectangle, including layer, changed by vkQueuePresentKHR for a given VkImage

Valid Usage

The sum of offset and extent must be no greater than the imageExtent member of the VkSwapchainCreateInfoKHR structure given to vkCreateSwapchainKHR.

layer must be less than imageArrayLayers member of the VkSwapchainCreateInfoKHR structure given to vkCreateSwapchainKHR.

Some platforms allow the size of a surface to change, and then scale the pixels of the image to fit the surface. VkRectLayerKHR specifies pixels of the swapchain’s image(s), which will be constant for the life of the swapchain.

VkRectLayerKHR
Fields vkOffset :: VkOffset2D `offset` is the origin of the rectangle, in pixels. vkExtent :: VkExtent2D `extent` is the size of the rectangle, in pixels. vkLayer :: Word32 `layer` is the layer of the image. For images with only one layer, the value of `layer` must be 0.
