C Specification

For a given image and swapchain, the region to present is specified by the VkPresentRegionKHR structure, which is defined as:

// Provided by VK_KHR_incremental_present
typedef struct VkPresentRegionKHR {
    uint32_t                 rectangleCount;
    const VkRectLayerKHR*    pRectangles;
} VkPresentRegionKHR;


  • rectangleCount is the number of rectangles in pRectangles, or zero if the entire image has changed and should be presented.

  • 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.


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
