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 valid VkRectLayerKHR structures

VkPresentRegionsKHR, VkRectLayerKHR

Member documentation
- rectangleCount – the number of rectangles in pRectangles, or zero if the entire image has changed and should be presented.
- pRectangles – 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.
