vkGetImageSubresourceLayout - Retrieve information about an image subresource

Parameters

• device is the logical device that owns the image.

• image is the image whose layout is being queried.
• pSubresource is a pointer to a ImageSubresource structure selecting a specific image for the image subresource.
• pLayout is a pointer to a SubresourceLayout structure in which the layout is returned.

Description

If the image is linear, then the returned layout is valid for host access.

If the image’s tiling is IMAGE_TILING_LINEAR and its format is a multi-planar format, then getImageSubresourceLayout describes one format plane of the image. If the image’s tiling is IMAGE_TILING_DRM_FORMAT_MODIFIER_EXT, then getImageSubresourceLayout describes one memory plane of the image. If the image’s tiling is IMAGE_TILING_DRM_FORMAT_MODIFIER_EXT and the image is non-linear, then the returned layout has an implementation-dependent meaning; the vendor of the image’s DRM format modifier may provide documentation that explains how to interpret the returned layout.

getImageSubresourceLayout is invariant for the lifetime of a single image. However, the subresource layout of images in Android hardware buffer external memory is not known until the image has been bound to memory, so applications must not call getImageSubresourceLayout for such an image before it has been bound.

Valid Usage

• image must have been created with tiling equal to IMAGE_TILING_LINEAR or IMAGE_TILING_DRM_FORMAT_MODIFIER_EXT

• The aspectMask member of pSubresource must only have a single bit set
• The mipLevel member of pSubresource must be less than the mipLevels specified in ImageCreateInfo when image was created
• The arrayLayer member of pSubresource must be less than the arrayLayers specified in ImageCreateInfo when image was created
• If the tiling of the image is IMAGE_TILING_LINEAR and its format is a multi-planar format with two planes, the aspectMask member of pSubresource must be IMAGE_ASPECT_PLANE_0_BIT or IMAGE_ASPECT_PLANE_1_BIT
• If the tiling of the image is IMAGE_TILING_LINEAR and its format is a multi-planar format with three planes, the aspectMask member of pSubresource must be IMAGE_ASPECT_PLANE_0_BIT, IMAGE_ASPECT_PLANE_1_BIT or IMAGE_ASPECT_PLANE_2_BIT
• If image was created with the EXTERNAL_MEMORY_HANDLE_TYPE_ANDROID_HARDWARE_BUFFER_BIT_ANDROID external memory handle type, then image must be bound to memory.
• If the tiling of the image is IMAGE_TILING_DRM_FORMAT_MODIFIER_EXT, then the aspectMask member of pSubresource must be VK_IMAGE_ASPECT_MEMORY_PLANE_i_BIT_EXT and the index i must be less than the drmFormatModifierPlaneCount associated with the image’s format and drmFormatModifier.

Valid Usage (Implicit)

• device must be a valid Device handle

• image must be a valid Image handle
• pSubresource must be a valid pointer to a valid ImageSubresource structure
• pLayout must be a valid pointer to a SubresourceLayout structure
• image must have been created, allocated, or retrieved from device

VkImageCreateInfo - Structure specifying the parameters of a newly created image object

Description

Images created with tiling equal to IMAGE_TILING_LINEAR have further restrictions on their limits and capabilities compared to images created with tiling equal to IMAGE_TILING_OPTIMAL. Creation of images with tiling IMAGE_TILING_LINEAR may not be supported unless other parameters meet all of the constraints:

• imageType is IMAGE_TYPE_2D
• format is not a depth/stencil format
• mipLevels is 1
• arrayLayers is 1
• samples is SAMPLE_COUNT_1_BIT
• usage only includes IMAGE_USAGE_TRANSFER_SRC_BIT and/or IMAGE_USAGE_TRANSFER_DST_BIT

Images created with a format from one of those listed in https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#formats-requiring-sampler-ycbcr-conversion have further restrictions on their limits and capabilities compared to images created with other formats. Creation of images with a format requiring Y′CBCR conversion may not be supported unless other parameters meet all of the constraints:

• imageType is IMAGE_TYPE_2D
• mipLevels is 1
• arrayLayers is 1
• samples is SAMPLE_COUNT_1_BIT

Implementations may support additional limits and capabilities beyond those listed above.

To determine the set of valid usage bits for a given format, call getPhysicalDeviceFormatProperties.

If the size of the resultant image would exceed maxResourceSize, then createImage must fail and return ERROR_OUT_OF_DEVICE_MEMORY. This failure may occur even when all image creation parameters satisfy their valid usage requirements.

Note

For images created without IMAGE_CREATE_EXTENDED_USAGE_BIT a usage bit is valid if it is supported for the format the image is created with.

For images created with IMAGE_CREATE_EXTENDED_USAGE_BIT a usage bit is valid if it is supported for at least one of the formats a ImageView created from the image can have (see Image Views for more detail).

Valid values for some image creation parameters are limited by a numerical upper bound or by inclusion in a bitset. For example, ImageCreateInfo::arrayLayers is limited by imageCreateMaxArrayLayers, defined below; and ImageCreateInfo::samples is limited by imageCreateSampleCounts, also defined below.

Several limiting values are defined below, as well as assisting values from which the limiting values are derived. The limiting values are referenced by the relevant valid usage statements of ImageCreateInfo.

  • If tiling is IMAGE_TILING_DRM_FORMAT_MODIFIER_EXT, then the value of imageCreateFormatFeatures is found by calling getPhysicalDeviceFormatProperties2 with ImageFormatProperties::format equal to ImageCreateInfo::format and with DrmFormatModifierPropertiesListEXT chained into ImageFormatProperties2; by collecting all members of the returned array DrmFormatModifierPropertiesListEXT::pDrmFormatModifierProperties whose drmFormatModifier belongs to imageCreateDrmFormatModifiers; and by taking the bitwise intersection, over the collected array members, of drmFormatModifierTilingFeatures.

    • If any call to getPhysicalDeviceImageFormatProperties2 returns an error, then imageCreateImageFormatPropertiesList is defined to be the empty list.

VkSubresourceLayout - Structure specifying subresource layout

Description

If the image is linear, then rowPitch, arrayPitch and depthPitch describe the layout of the image subresource in linear memory. For uncompressed formats, rowPitch is the number of bytes between texels with the same x coordinate in adjacent rows (y coordinates differ by one). arrayPitch is the number of bytes between texels with the same x and y coordinate in adjacent array layers of the image (array layer values differ by one). depthPitch is the number of bytes between texels with the same x and y coordinate in adjacent slices of a 3D image (z coordinates differ by one). Expressed as an addressing formula, the starting byte of a texel in the image subresource has address:

// (x,y,z,layer) are in texel coordinates
address(x,y,z,layer) = layer*arrayPitch + z*depthPitch + y*rowPitch + x*elementSize + offset

For compressed formats, the rowPitch is the number of bytes between compressed texel blocks in adjacent rows. arrayPitch is the number of bytes between compressed texel blocks in adjacent array layers. depthPitch is the number of bytes between compressed texel blocks in adjacent slices of a 3D image.

// (x,y,z,layer) are in compressed texel block coordinates
address(x,y,z,layer) = layer*arrayPitch + z*depthPitch + y*rowPitch + x*compressedTexelBlockByteSize + offset;

The value of arrayPitch is undefined for images that were not created as arrays. depthPitch is defined only for 3D images.

If the image has a single-plane color format and its tiling is IMAGE_TILING_LINEAR , then the aspectMask member of ImageSubresource must be IMAGE_ASPECT_COLOR_BIT.

If the image has a depth/stencil format and its tiling is IMAGE_TILING_LINEAR , then aspectMask must be either IMAGE_ASPECT_DEPTH_BIT or IMAGE_ASPECT_STENCIL_BIT. On implementations that store depth and stencil aspects separately, querying each of these image subresource layouts will return a different offset and size representing the region of memory used for that aspect. On implementations that store depth and stencil aspects interleaved, the same offset and size are returned and represent the interleaved memory allocation.

If the image has a multi-planar format and its tiling is IMAGE_TILING_LINEAR , then the aspectMask member of ImageSubresource must be IMAGE_ASPECT_PLANE_0_BIT, IMAGE_ASPECT_PLANE_1_BIT, or (for 3-plane formats only) IMAGE_ASPECT_PLANE_2_BIT. Querying each of these image subresource layouts will return a different offset and size representing the region of memory used for that plane. If the image is disjoint, then the offset is relative to the base address of the plane. If the image is non-disjoint, then the offset is relative to the base address of the image.

If the image’s tiling is IMAGE_TILING_DRM_FORMAT_MODIFIER_EXT, then the aspectMask member of ImageSubresource must be one of VK_IMAGE_ASPECT_MEMORY_PLANE_i_BIT_EXT, where the maximum allowed plane index i is defined by the drmFormatModifierPlaneCount associated with the image’s format and modifier. The memory range used by the subresource is described by offset and size. If the image is disjoint, then the offset is relative to the base address of the memory plane. If the image is non-disjoint, then the offset is relative to the base address of the image. If the image is non-linear, then rowPitch, arrayPitch, and depthPitch have an implementation-dependent meaning.
