## Name

VkHostImageLayoutTransitionInfo - Structure specifying the parameters of a host-side image layout transition

Loading… please wait.

## C Specification

The `VkHostImageLayoutTransitionInfo` structure is defined as:

    // Provided by VK_VERSION_1_4
    typedef struct VkHostImageLayoutTransitionInfo {
        VkStructureType            sType;
        const void*                pNext;
        VkImage                    image;
        VkImageLayout              oldLayout;
        VkImageLayout              newLayout;
        VkImageSubresourceRange    subresourceRange;
    } VkHostImageLayoutTransitionInfo;

or the equivalent

    // Provided by VK_EXT_host_image_copy
    typedef VkHostImageLayoutTransitionInfo VkHostImageLayoutTransitionInfoEXT;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `image` is a handle to the image affected by this layout transition.

- `oldLayout` is the old layout in an image layout transition.

- `newLayout` is the new layout in an image layout transition.

- `subresourceRange` describes the image subresource range within `image` that is affected by this layout transition.

## Description

`vkTransitionImageLayout` does not check whether the device memory associated with an image is currently in use before performing the layout transition. The application must guarantee that any previously submitted command that reads from or writes to this subresource has completed before the host performs the layout transition. The memory of `image` is accessed by the host as if coherent.

If `image` is a 3D image created with `VK_IMAGE_CREATE_2D_ARRAY_COMPATIBLE_BIT` and the `maintenance9` feature is enabled, the `baseArrayLayer` and `layerCount` members of `subresourceRange` specify the subset of slices of the 3D image affected by the memory barrier, including the layout transition. Any slices of a 3D image not included in `subresourceRange` are not affected by the memory barrier and remain in their existing layout.

Note | Image layout transitions performed on the host do not require queue family ownership transfers as the physical layout of the image will not vary between queue families for the layouts supported by this function.

Note | If the device has written to the image memory, it is not automatically made available to the host. Before this command can be called, a memory barrier for this image must have been issued on the device with the second synchronization scope including `VK_PIPELINE_STAGE_HOST_BIT` and `VK_ACCESS_HOST_READ_BIT`. Because queue submissions automatically make host memory visible to the device, there would not be a need for a memory barrier before using the results of this layout transition on the device.
