## 32. Formats

Supported buffer and image formats may vary across implementations. A minimum set of format features are guaranteed, but others must be explicitly queried before use to ensure they are supported by the implementation.

The features for the set of formats (VkFormat) supported by the implementation are queried individually using the vkGetPhysicalDeviceFormatProperties command.

### 32.1. Format Definition

The following image formats can be passed to, and may be returned from Vulkan commands. The memory required to store each format is discussed with that format, and also summarized in the Representation and Texel Block Size section and the Compatible formats table.

#### 32.1.3. Identification of Formats

A “format” is represented by a single enum value. The name of a format is usually built up by using the following pattern:

    VK_FORMAT_{component-format|compression-scheme}_{numeric-format}

The component-format indicates either the size of the R, G, B, and A components (if they are present) in the case of a color format, or the size of the depth (D) and stencil (S) components (if they are present) in the case of a depth/stencil format (see below). An X indicates a component that is unused, but may be present for padding.

Table 34. Interpretation of Numeric Format
Numeric format SPIR-V Sampled Type Description

UNORM

OpTypeFloat

The components are unsigned normalized values in the range [0,1]

SNORM

OpTypeFloat

The components are signed normalized values in the range [-1,1]

USCALED

OpTypeFloat

The components are unsigned integer values that get converted to floating-point in the range [0,2n-1]

SSCALED

OpTypeFloat

The components are signed integer values that get converted to floating-point in the range [-2n-1,2n-1-1]

UINT

OpTypeInt

The components are unsigned integer values in the range [0,2n-1]

SINT

OpTypeInt

The components are signed integer values in the range [-2n-1,2n-1-1]

UFLOAT

OpTypeFloat

The components are unsigned floating-point numbers (used by packed, shared exponent, and some compressed formats)

SFLOAT

OpTypeFloat

The components are signed floating-point numbers

SRGB

OpTypeFloat

The R, G, and B components are unsigned normalized values that represent values using sRGB nonlinear encoding, while the A component (if one exists) is a regular unsigned normalized value

The suffix _PACKnn indicates that the format is packed into an underlying type with nn bits. The suffix _mPACKnn is a short-hand that indicates that the format has several components (which may or may not be stored in separate planes) that are each packed into an underlying type with nn bits.

The suffix _BLOCK indicates that the format is a block-compressed format, with the representation of multiple pixels encoded interdependently within a region.

Table 35. Interpretation of Compression Scheme
Compression scheme Description

BC

Block Compression. See Block-Compressed Image Formats.

ETC2

Ericsson Texture Compression. See ETC Compressed Image Formats.

EAC

ETC2 Alpha Compression. See ETC Compressed Image Formats.

ASTC

Adaptive Scalable Texture Compression (LDR Profile). See ASTC Compressed Image Formats.

For multi-planar images, the components in separate planes are separated by underscores, and the number of planes is indicated by the addition of a _2PLANE or _3PLANE suffix. Similarly, the separate aspects of depth-stencil formats are separated by underscores, although these are not considered separate planes. Formats are suffixed by _422 to indicate that planes other than the first are reduced in size by a factor of two horizontally or that the R and B values appear at half the horizontal frequency of the G values, _420 to indicate that planes other than the first are reduced in size by a factor of two both horizontally and vertically, and _444 for consistency to indicate that all three planes of a three-planar image are the same size.

 Note No common format has a single plane containing both R and B channels but does not store these channels at reduced horizontal resolution.

#### 32.1.4. Representation and Texel Block Size

Color formats must be represented in memory in exactly the form indicated by the format’s name. This means that promoting one format to another with more bits per component and/or additional components must not occur for color formats. Depth/stencil formats have more relaxed requirements as discussed below.

Each format has a texel block size, the number of bytes used to store one texel block (a single addressable element of an uncompressed image, or a single compressed block of a compressed image). The texel block size for each format is shown in the Compatible formats table.

The representation of non-packed formats is that the first component specified in the name of the format is in the lowest memory addresses and the last component specified is in the highest memory addresses. See Byte mappings for non-packed/compressed color formats. The in-memory ordering of bytes within a component is determined by the host endianness.

Packed formats store multiple components within one underlying type. The bit representation is that the first component specified in the name of the format is in the most-significant bits and the last component specified is in the least-significant bits of the underlying type. The in-memory ordering of bytes comprising the underlying type is determined by the host endianness.

#### 32.1.5. Depth/Stencil Formats

Depth/stencil formats are considered opaque and need not be stored in the exact number of bits per texel or component ordering indicated by the format enum. However, implementations must not substitute a different depth or stencil precision than that described in the format (e.g. D16 must not be implemented as D24 or D32).

#### 32.1.6. Format Compatibility Classes

Uncompressed color formats are compatible with each other if they occupy the same number of bits per texel block. Compressed color formats are compatible with each other if the only difference between them is the numerical type of the uncompressed pixels (e.g. signed vs. unsigned, or SRGB vs. UNORM encoding). Each depth/stencil format is only compatible with itself. In the following table, all the formats in the same row are compatible.

### 32.2. Format Properties

To query supported format features which are properties of the physical device, call:

// Provided by VK_VERSION_1_0
void vkGetPhysicalDeviceFormatProperties(
VkPhysicalDevice                            physicalDevice,
VkFormat                                    format,
VkFormatProperties*                         pFormatProperties);
• physicalDevice is the physical device from which to query the format properties.

• format is the format whose properties are queried.

• pFormatProperties is a pointer to a VkFormatProperties structure in which physical device properties for format are returned.

Valid Usage (Implicit)
• physicalDevice must be a valid VkPhysicalDevice handle

• format must be a valid VkFormat value

• pFormatProperties must be a valid pointer to a VkFormatProperties structure

The VkFormatProperties structure is defined as:

// Provided by VK_VERSION_1_0
typedef struct VkFormatProperties {
VkFormatFeatureFlags    linearTilingFeatures;
VkFormatFeatureFlags    optimalTilingFeatures;
VkFormatFeatureFlags    bufferFeatures;
} VkFormatProperties;
• linearTilingFeatures is a bitmask of VkFormatFeatureFlagBits specifying features supported by images created with a tiling parameter of VK_IMAGE_TILING_LINEAR.

• optimalTilingFeatures is a bitmask of VkFormatFeatureFlagBits specifying features supported by images created with a tiling parameter of VK_IMAGE_TILING_OPTIMAL.

• bufferFeatures is a bitmask of VkFormatFeatureFlagBits specifying features supported by buffers.

 Note If no format feature flags are supported, the format itself is not supported, and images of that format cannot be created.

If format is a block-compressed format, then bufferFeatures must not support any features for the format.

If format is not a multi-plane format then linearTilingFeatures and optimalTilingFeatures must not contain VK_FORMAT_FEATURE_DISJOINT_BIT.

Bits which can be set in the VkFormatProperties features linearTilingFeatures, optimalTilingFeatures, and bufferFeatures are:

// Provided by VK_VERSION_1_0
typedef enum VkFormatFeatureFlagBits {
VK_FORMAT_FEATURE_SAMPLED_IMAGE_BIT = 0x00000001,
VK_FORMAT_FEATURE_STORAGE_IMAGE_BIT = 0x00000002,
VK_FORMAT_FEATURE_STORAGE_IMAGE_ATOMIC_BIT = 0x00000004,
VK_FORMAT_FEATURE_UNIFORM_TEXEL_BUFFER_BIT = 0x00000008,
VK_FORMAT_FEATURE_STORAGE_TEXEL_BUFFER_BIT = 0x00000010,

VK_FORMAT_FEATURE_COLOR_ATTACHMENT_BLEND_BIT = 0x00000100,
VK_FORMAT_FEATURE_DEPTH_STENCIL_ATTACHMENT_BIT = 0x00000200,
VK_FORMAT_FEATURE_BLIT_SRC_BIT = 0x00000400,
VK_FORMAT_FEATURE_BLIT_DST_BIT = 0x00000800,
VK_FORMAT_FEATURE_SAMPLED_IMAGE_FILTER_LINEAR_BIT = 0x00001000,
// Provided by VK_VERSION_1_1
VK_FORMAT_FEATURE_TRANSFER_SRC_BIT = 0x00004000,
// Provided by VK_VERSION_1_1
VK_FORMAT_FEATURE_TRANSFER_DST_BIT = 0x00008000,
// Provided by VK_VERSION_1_1
VK_FORMAT_FEATURE_MIDPOINT_CHROMA_SAMPLES_BIT = 0x00020000,
// Provided by VK_VERSION_1_1
VK_FORMAT_FEATURE_SAMPLED_IMAGE_YCBCR_CONVERSION_LINEAR_FILTER_BIT = 0x00040000,
// Provided by VK_VERSION_1_1
VK_FORMAT_FEATURE_SAMPLED_IMAGE_YCBCR_CONVERSION_SEPARATE_RECONSTRUCTION_FILTER_BIT = 0x00080000,
// Provided by VK_VERSION_1_1
VK_FORMAT_FEATURE_SAMPLED_IMAGE_YCBCR_CONVERSION_CHROMA_RECONSTRUCTION_EXPLICIT_BIT = 0x00100000,
// Provided by VK_VERSION_1_1
VK_FORMAT_FEATURE_SAMPLED_IMAGE_YCBCR_CONVERSION_CHROMA_RECONSTRUCTION_EXPLICIT_FORCEABLE_BIT = 0x00200000,
// Provided by VK_VERSION_1_1
VK_FORMAT_FEATURE_DISJOINT_BIT = 0x00400000,
// Provided by VK_VERSION_1_1
VK_FORMAT_FEATURE_COSITED_CHROMA_SAMPLES_BIT = 0x00800000,
} VkFormatFeatureFlagBits;

The following bits may be set in linearTilingFeatures and optimalTilingFeatures, specifying that the features are supported by images or image views or sampler Y′CBCR conversion objects created with the queried vkGetPhysicalDeviceFormatProperties::format:

• VK_FORMAT_FEATURE_SAMPLED_IMAGE_BIT specifies that an image view can be sampled from.

• VK_FORMAT_FEATURE_STORAGE_IMAGE_BIT specifies that an image view can be used as a storage images.

• VK_FORMAT_FEATURE_STORAGE_IMAGE_ATOMIC_BIT specifies that an image view can be used as storage image that supports atomic operations.

• VK_FORMAT_FEATURE_COLOR_ATTACHMENT_BIT specifies that an image view can be used as a framebuffer color attachment and as an input attachment.

• VK_FORMAT_FEATURE_COLOR_ATTACHMENT_BLEND_BIT specifies that an image view can be used as a framebuffer color attachment that supports blending and as an input attachment.

• VK_FORMAT_FEATURE_DEPTH_STENCIL_ATTACHMENT_BIT specifies that an image view can be used as a framebuffer depth/stencil attachment and as an input attachment.

• VK_FORMAT_FEATURE_BLIT_SRC_BIT specifies that an image can be used as srcImage for the vkCmdBlitImage command.

• VK_FORMAT_FEATURE_BLIT_DST_BIT specifies that an image can be used as dstImage for the vkCmdBlitImage command.

• VK_FORMAT_FEATURE_SAMPLED_IMAGE_FILTER_LINEAR_BIT specifies that if VK_FORMAT_FEATURE_SAMPLED_IMAGE_BIT is also set, an image view can be used with a sampler that has either of magFilter or minFilter set to VK_FILTER_LINEAR, or mipmapMode set to VK_SAMPLER_MIPMAP_MODE_LINEAR. If VK_FORMAT_FEATURE_BLIT_SRC_BIT is also set, an image can be used as the srcImage to vkCmdBlitImage with a filter of VK_FILTER_LINEAR. This bit must only be exposed for formats that also support the VK_FORMAT_FEATURE_SAMPLED_IMAGE_BIT or VK_FORMAT_FEATURE_BLIT_SRC_BIT.

If the format being queried is a depth/stencil format, this bit only specifies that the depth aspect (not the stencil aspect) of an image of this format supports linear filtering, and that linear filtering of the depth aspect is supported whether depth compare is enabled in the sampler or not. If this bit is not present, linear filtering with depth compare disabled is unsupported and linear filtering with depth compare enabled is supported, but may compute the filtered value in an implementation-dependent manner which differs from the normal rules of linear filtering. The resulting value must be in the range [0,1] and should be proportional to, or a weighted average of, the number of comparison passes or failures.

• VK_FORMAT_FEATURE_TRANSFER_SRC_BIT specifies that an image can be used as a source image for copy commands.

• VK_FORMAT_FEATURE_TRANSFER_DST_BIT specifies that an image can be used as a destination image for copy commands and clear commands.

• VK_FORMAT_FEATURE_MIDPOINT_CHROMA_SAMPLES_BIT specifies that an application can define a sampler Y′CBCR conversion using this format as a source, and that an image of this format can be used with a VkSamplerYcbcrConversionCreateInfo xChromaOffset and/or yChromaOffset of VK_CHROMA_LOCATION_MIDPOINT. Otherwise both xChromaOffset and yChromaOffset must be VK_CHROMA_LOCATION_COSITED_EVEN. If a format does not incorporate chroma downsampling (it is not a “422” or “420” format) but the implementation supports sampler Y′CBCR conversion for this format, the implementation must set VK_FORMAT_FEATURE_MIDPOINT_CHROMA_SAMPLES_BIT.

• VK_FORMAT_FEATURE_COSITED_CHROMA_SAMPLES_BIT specifies that an application can define a sampler Y′CBCR conversion using this format as a source, and that an image of this format can be used with a VkSamplerYcbcrConversionCreateInfo xChromaOffset and/or yChromaOffset of VK_CHROMA_LOCATION_COSITED_EVEN. Otherwise both xChromaOffset and yChromaOffset must be VK_CHROMA_LOCATION_MIDPOINT. If neither VK_FORMAT_FEATURE_COSITED_CHROMA_SAMPLES_BIT nor VK_FORMAT_FEATURE_MIDPOINT_CHROMA_SAMPLES_BIT is set, the application must not define a sampler Y′CBCR conversion using this format as a source.

• VK_FORMAT_FEATURE_SAMPLED_IMAGE_YCBCR_CONVERSION_LINEAR_FILTER_BIT specifies that the format can do linear sampler filtering (min/magFilter) whilst sampler Y′CBCR conversion is enabled.

• VK_FORMAT_FEATURE_SAMPLED_IMAGE_YCBCR_CONVERSION_SEPARATE_RECONSTRUCTION_FILTER_BIT specifies that the format can have different chroma, min, and mag filters.

• VK_FORMAT_FEATURE_SAMPLED_IMAGE_YCBCR_CONVERSION_CHROMA_RECONSTRUCTION_EXPLICIT_BIT specifies that reconstruction is explicit, as described in Chroma Reconstruction. If this bit is not present, reconstruction is implicit by default.

• VK_FORMAT_FEATURE_SAMPLED_IMAGE_YCBCR_CONVERSION_CHROMA_RECONSTRUCTION_EXPLICIT_FORCEABLE_BIT specifies that reconstruction can be forcibly made explicit by setting VkSamplerYcbcrConversionCreateInfo::forceExplicitReconstruction to VK_TRUE. If the format being queried supports VK_FORMAT_FEATURE_SAMPLED_IMAGE_YCBCR_CONVERSION_CHROMA_RECONSTRUCTION_EXPLICIT_BIT it must also support VK_FORMAT_FEATURE_SAMPLED_IMAGE_YCBCR_CONVERSION_CHROMA_RECONSTRUCTION_EXPLICIT_FORCEABLE_BIT.

• VK_FORMAT_FEATURE_DISJOINT_BIT specifies that a multi-planar image can have the VK_IMAGE_CREATE_DISJOINT_BIT set during image creation. An implementation must not set VK_FORMAT_FEATURE_DISJOINT_BIT for single-plane formats.

The following bits may be set in bufferFeatures, specifying that the features are supported by buffers or buffer views created with the queried vkGetPhysicalDeviceProperties::format:

• VK_FORMAT_FEATURE_UNIFORM_TEXEL_BUFFER_BIT specifies that the format can be used to create a buffer view that can be bound to a VK_DESCRIPTOR_TYPE_UNIFORM_TEXEL_BUFFER descriptor.

• VK_FORMAT_FEATURE_STORAGE_TEXEL_BUFFER_BIT specifies that the format can be used to create a buffer view that can be bound to a VK_DESCRIPTOR_TYPE_STORAGE_TEXEL_BUFFER descriptor.

• VK_FORMAT_FEATURE_STORAGE_TEXEL_BUFFER_ATOMIC_BIT specifies that atomic operations are supported on VK_DESCRIPTOR_TYPE_STORAGE_TEXEL_BUFFER with this format.

• VK_FORMAT_FEATURE_VERTEX_BUFFER_BIT specifies that the format can be used as a vertex attribute format (VkVertexInputAttributeDescription::format).

// Provided by VK_VERSION_1_0
typedef VkFlags VkFormatFeatureFlags;

VkFormatFeatureFlags is a bitmask type for setting a mask of zero or more VkFormatFeatureFlagBits.

To query supported format features which are properties of the physical device, call:

// Provided by VK_VERSION_1_1
void vkGetPhysicalDeviceFormatProperties2(
VkPhysicalDevice                            physicalDevice,
VkFormat                                    format,
VkFormatProperties2*                        pFormatProperties);
• physicalDevice is the physical device from which to query the format properties.

• format is the format whose properties are queried.

• pFormatProperties is a pointer to a VkFormatProperties2 structure in which physical device properties for format are returned.

vkGetPhysicalDeviceFormatProperties2 behaves similarly to vkGetPhysicalDeviceFormatProperties, with the ability to return extended information in a pNext chain of output structures.

Valid Usage (Implicit)

The VkFormatProperties2 structure is defined as:

// Provided by VK_VERSION_1_1
typedef struct VkFormatProperties2 {
VkStructureType       sType;
void*                 pNext;
VkFormatProperties    formatProperties;
} VkFormatProperties2;
• sType is the type of this structure.

• pNext is NULL or a pointer to a structure extending this structure.

• formatProperties is a VkFormatProperties structure describing features supported by the requested format.

Valid Usage (Implicit)
• sType must be VK_STRUCTURE_TYPE_FORMAT_PROPERTIES_2

• pNext must be NULL

#### 32.2.1. Potential Format Features

Some valid usage conditions depend on the format features supported by an VkImage whose VkImageTiling is unknown. In such cases the exact VkFormatFeatureFlagBits supported by the VkImage cannot be determined, so the valid usage conditions are expressed in terms of the potential format features of the VkImage format.

The potential format features of a VkFormat are defined as follows:

### 32.3. Required Format Support

Implementations must support at least the following set of features on the listed formats. For images, these features must be supported for every VkImageType (including arrayed and cube variants) unless otherwise noted. These features are supported on existing formats without needing to advertise an extension or needing to explicitly enable them. Support for additional functionality beyond the requirements listed here is queried using the vkGetPhysicalDeviceFormatProperties command.

 Note Unless otherwise excluded below, the required formats are supported for all VkImageCreateFlags values as long as those flag values are otherwise allowed.

The following tables show which feature bits must be supported for each format. Formats that are required to support VK_FORMAT_FEATURE_SAMPLED_IMAGE_BIT must also support VK_FORMAT_FEATURE_TRANSFER_SRC_BIT and VK_FORMAT_FEATURE_TRANSFER_DST_BIT.
