VkImageDescriptorInfoEXT

Structure describing an image descriptor created from an image

VkImageDescriptorInfoEXT is defined as:

typedef struct VkImageDescriptorInfoEXT {
    VkStructureType sType;
    const void* pNext;
    const VkImageViewCreateInfo* pView;
    VkImageLayout layout;
} VkImageDescriptorInfoEXT;
  • sType is a VkStructureType value identifying this structure.
  • pNext is NULL or a pointer to a structure extending this structure.
  • pView is an VkImageViewCreateInfo describing the descriptor.
  • layout is the VkImageLayout that the image view will be in when accessed as a descriptor.

Valid Usage

VUID-VkImageDescriptorInfoEXT-pView-11426

pView→viewType must not be VK_IMAGE_VIEW_TYPE_2D_ARRAY if pView→image was created with an imageType of VK_IMAGE_TYPE_3D

VUID-VkImageDescriptorInfoEXT-pView-11427

If pView→viewType is VK_IMAGE_VIEW_TYPE_2D and pView→image was created with an imageType of VK_IMAGE_TYPE_3D, pView→image must have been created with VK_IMAGE_CREATE_2D_VIEW_COMPATIBLE_BIT_EXT set

VUID-VkImageDescriptorInfoEXT-layout-11219

layout must be VK_IMAGE_LAYOUT_DEPTH_STENCIL_READ_ONLY_OPTIMAL, VK_IMAGE_LAYOUT_SHADER_READ_ONLY_OPTIMAL, VK_IMAGE_LAYOUT_DEPTH_READ_ONLY_STENCIL_ATTACHMENT_OPTIMAL, VK_IMAGE_LAYOUT_DEPTH_ATTACHMENT_STENCIL_READ_ONLY_OPTIMAL, VK_IMAGE_LAYOUT_DEPTH_READ_ONLY_OPTIMAL, VK_IMAGE_LAYOUT_STENCIL_READ_ONLY_OPTIMAL, VK_IMAGE_LAYOUT_READ_ONLY_OPTIMAL, VK_IMAGE_LAYOUT_SHARED_PRESENT_KHR, VK_IMAGE_LAYOUT_RENDERING_LOCAL_READ_KHR, VK_IMAGE_LAYOUT_ATTACHMENT_FEEDBACK_LOOP_OPTIMAL_EXT, or VK_IMAGE_LAYOUT_GENERAL

VUID-VkImageDescriptorInfoEXT-layout-11221

If `layout` is
`VK_IMAGE_LAYOUT_DEPTH_READ_ONLY_STENCIL_ATTACHMENT_OPTIMAL`,
`VK_IMAGE_LAYOUT_DEPTH_ATTACHMENT_STENCIL_READ_ONLY_OPTIMAL`,
`VK_IMAGE_LAYOUT_DEPTH_READ_ONLY_OPTIMAL`,
`VK_IMAGE_LAYOUT_STENCIL_READ_ONLY_OPTIMAL`,

or VK_IMAGE_LAYOUT_DEPTH_STENCIL_READ_ONLY_OPTIMAL, then pView→aspectMask must not include VK_IMAGE_ASPECT_COLOR_BIT

VUID-VkImageDescriptorInfoEXT-pView-11430

If pView→image is a depth/stencil image, pView→subresourceRange.aspectMask must include either VK_IMAGE_ASPECT_DEPTH_BIT or VK_IMAGE_ASPECT_STENCIL_BIT but not both

VUID-VkImageDescriptorInfoEXT-pNext-pNext

pNext must be NULL

VUID-VkImageDescriptorInfoEXT-pView-parameter

pView must be a valid pointer to a valid VkImageViewCreateInfo structure

VUID-VkImageDescriptorInfoEXT-layout-parameter
