# VkExportMetalTextureInfoEXT(3) Manual Page

## Name

VkExportMetalTextureInfoEXT - Structure that identifies a VkImage, VkImageView, or VkBufferView object and corresponding Metal MTLTexture object

Loading… please wait.

## C Specification

To export a Metal `MTLTexture` object underlying a VkImage, VkImageView, or VkBufferView object, include a `VkExportMetalTextureInfoEXT` structure in the `pNext` chain of the `pMetalObjectsInfo` parameter of a vkExportMetalObjectsEXT call.

The `VkExportMetalTextureInfoEXT` structure is defined as:

    // Provided by VK_EXT_metal_objects
    typedef struct VkExportMetalTextureInfoEXT {
        VkStructureType          sType;
        const void*              pNext;
        VkImage                  image;
        VkImageView              imageView;
        VkBufferView             bufferView;
        VkImageAspectFlagBits    plane;
        MTLTexture_id            mtlTexture;
    } VkExportMetalTextureInfoEXT;

## Members

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

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

- `image` is VK_NULL_HANDLE or a VkImage.

- `imageView` is VK_NULL_HANDLE or a VkImageView.

- `bufferView` is VK_NULL_HANDLE or a VkBufferView.

- `plane` specifies the plane of a multi-planar VkImage or VkImageView.

- `mtlTexture` is the Metal `id<MTLTexture>` object underlying the VkImage, VkImageView, or VkBufferView object in `image`, `imageView`, or `bufferView`, respectively, at the plane indicated in `aspectMask`. The implementation will return the `MTLTexture` in this member, or it will return `NULL` if no `MTLTexture` could be found underlying the VkImage, VkImageView, or VkBufferView object, at the plane indicated in `aspectMask`.

## Description

Valid Usage (Implicit)

- VUID-VkExportMetalTextureInfoEXT-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_EXPORT_METAL_TEXTURE_INFO_EXT`

- VUID-VkExportMetalTextureInfoEXT-image-parameter
  If `image` is not VK_NULL_HANDLE, `image` must be a valid VkImage handle

- VUID-VkExportMetalTextureInfoEXT-imageView-parameter
  If `imageView` is not VK_NULL_HANDLE, `imageView` must be a valid VkImageView handle

- VUID-VkExportMetalTextureInfoEXT-bufferView-parameter
  If `bufferView` is not VK_NULL_HANDLE, `bufferView` must be a valid VkBufferView handle

- VUID-VkExportMetalTextureInfoEXT-plane-parameter
  `plane` must be a valid VkImageAspectFlagBits value

- VUID-VkExportMetalTextureInfoEXT-commonparent
  Each of `bufferView`, `image`, and `imageView` that are valid handles of non-ignored parameters must have been created, allocated, or retrieved from the same VkDevice
