# VkImagePlaneMemoryRequirementsInfo(3) Manual Page

## Name

VkImagePlaneMemoryRequirementsInfo - Structure specifying image plane for memory requirements

## C Specification

To determine the memory requirements for a plane of a disjoint image, add a `VkImagePlaneMemoryRequirementsInfo` structure to the `pNext` chain of the `VkImageMemoryRequirementsInfo2` structure.

The `VkImagePlaneMemoryRequirementsInfo` structure is defined as:

    typedef struct VkImagePlaneMemoryRequirementsInfo {
        VkStructureType          sType;
        const void*              pNext;
        VkImageAspectFlagBits    planeAspect;
    } VkImagePlaneMemoryRequirementsInfo;

or the equivalent

    typedef VkImagePlaneMemoryRequirementsInfo VkImagePlaneMemoryRequirementsInfoKHR;

## Members

- `sType` is the type of this structure.

- `pNext` is `NULL` or a pointer to an extension-specific structure.

- `planeAspect` is the aspect corresponding to the image plane to query.

## Description

Valid Usage

- If the image’s tiling is `VK_IMAGE_TILING_LINEAR` or `VK_IMAGE_TILING_OPTIMAL`, then `planeAspect` must be a single valid format plane for the image. (That is, for a two-plane image `planeAspect` must be `VK_IMAGE_ASPECT_PLANE_0_BIT` or `VK_IMAGE_ASPECT_PLANE_1_BIT`, and for a three-plane image `planeAspect` must be `VK_IMAGE_ASPECT_PLANE_0_BIT`, `VK_IMAGE_ASPECT_PLANE_1_BIT` or `VK_IMAGE_ASPECT_PLANE_2_BIT`).

- If the image’s tiling is `VK_IMAGE_TILING_DRM_FORMAT_MODIFIER_EXT`, then `planeAspect` must be a single valid memory plane for the image. (That is, `aspectMask` must specify a plane index that is less than the `drmFormatModifierPlaneCount` associated with the image’s `format` and `drmFormatModifier`.)

Valid Usage (Implicit)

- `sType` must be `VK_STRUCTURE_TYPE_IMAGE_PLANE_MEMORY_REQUIREMENTS_INFO`

- `planeAspect` must be a valid VkImageAspectFlagBits value
