VkPresentRegionKHR(3)

# VkPresentRegionKHR(3) Manual Page

## Name

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

## C Specification

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

    typedef struct VkPresentRegionKHR {
        uint32_t                 rectangleCount;
        const VkRectLayerKHR*    pRectangles;
    } VkPresentRegionKHR;

## Members

- `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.

## Description

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
