Direct3D 11.1:  This value is not supported until Windows 8.

DXGI_FORMAT_P010

10-bit per channel planar YUV 4:2:0 video resource format. Valid luminance data view formats for this video resource format are DXGI_FORMAT_R16_UNORM and DXGI_FORMAT_R16_UINT. The runtime does not enforce whether the lowest 6 bits are 0 (given that this video resource format is a 10-bit format that uses 16 bits). If required, application shader code would have to enforce this manually. From the runtime's point of view, DXGI_FORMAT_P010 is no different than DXGI_FORMAT_P016. Valid chrominance data view formats (width and height are each 1/2 of luminance view) for this video resource format are DXGI_FORMAT_R16G16_UNORM and DXGI_FORMAT_R16G16_UINT. For UAVs, an additional valid chrominance data view format is DXGI_FORMAT_R32_UINT. By using DXGI_FORMAT_R32_UINT for UAVs, you can both read and write as opposed to just write for DXGI_FORMAT_R16G16_UNORM and DXGI_FORMAT_R16G16_UINT. Supported view types are SRV, RTV, and UAV.

Direct3D 11.1:  This value is not supported until Windows 8.

DXGI_FORMAT_420_OPAQUE

8-bit per channel planar YUV 4:2:0 video resource format. This format is subsampled where each pixel has its own Y value, but each 2x2 pixel block shares a single U and V value. The runtime requires that the width and height of all resources that are created with this format are multiples of 2. The runtime also requires that the left, right, top, and bottom members of any RECT that are used for this format are multiples of 2. This format differs from DXGI_FORMAT_NV12 in that the layout of the data within the resource is completely opaque to applications. Applications cannot use the CPU to map the resource and then access the data within the resource. You cannot use shaders with this format. Because of this behavior, legacy hardware that supports a non-NV12 4:2:0 layout (for example, YV12, and so on) can be used. Also, new hardware that has a 4:2:0 implementation better than NV12 can be used when the application does not need the data to be in a standard layout.

For more info about YUV formats for video rendering, see Recommended 8-Bit YUV Formats for Video Rendering.

Width and height must be even. Direct3D 11 staging resources and initData parameters for this format use (rowPitch * (height + (height / 2))) bytes.

DXGI_FORMAT_YUY2

Most common YUV 4:2:2 video resource format. Valid view formats for this video resource format are DXGI_FORMAT_R8G8B8A8_UNORM and DXGI_FORMAT_R8G8B8A8_UINT. For UAVs, an additional valid view format is DXGI_FORMAT_R32_UINT. By using DXGI_FORMAT_R32_UINT for UAVs, you can both read and write as opposed to just write for DXGI_FORMAT_R8G8B8A8_UNORM and DXGI_FORMAT_R8G8B8A8_UINT. Supported view types are SRV and UAV. One view provides a straightforward mapping of the entire surface. The mapping to the view channel is Y0->R8, U0->G8, Y1->B8, and V0->A8.

A unique valid view format for this video resource format is DXGI_FORMAT_R8G8_B8G8_UNORM. With this view format, the width of the view appears to be twice what the DXGI_FORMAT_R8G8B8A8_UNORM or DXGI_FORMAT_R8G8B8A8_UINT view would be when hardware reconstructs RGBA automatically on read and before filtering. This Direct3D hardware behavior is legacy and is likely not useful any more. With this view format, the mapping to the view channel is Y0->R8, U0-> G8[0], Y1->B8, and V0-> G8[1].

DXGI_FORMAT_FORCE_UINT

Forces this enumeration to compile to 32 bits in size. Without this value, some compilers would allow this enumeration to compile to a size other than 32 bits. This value is not used.

Remarks

A few formats have additional restrictions.

  1. A resource declared with the DXGI_FORMAT_R32G32B32 family of formats cannot be used simultaneously for vertex and texture data. That is, you may not create a buffer resource with the DXGI_FORMAT_R32G32B32 family of formats that uses any of the following bind flags: D3D10_BIND_VERTEX_BUFFER, D3D10_BIND_INDEX_BUFFER, D3D10_BIND_CONSTANT_BUFFER, or D3D10_BIND_STREAM_OUTPUT (see D3D10_BIND_FLAG).
  2. DXGI_FORMAT_R1_UNORM is designed specifically for text filtering, and must be used with a format-specific, configurable 8x8 filter mode. When calling an HLSL sampling function using this format, the address offset parameter must be set to (0,0).
  3. A resource using a sub-sampled format (such as DXGI_FORMAT_R8G8_B8G8) must have a size that is a multiple of 2 in the x dimension.
  4. Format is not available in Direct3D 10 and Direct3D 10.1

The following topics provide lists of the formats that particular hardware feature levels support:

For a list of the DirectXMath types that map to DXGI_FORMAT values, see DirectXMath Library Internals.

Format Modifiers

Each enumeration value contains a format modifier which describes the data type.

Format ModifiersDescription
_FLOATA floating-point value; 32-bit floating-point formats use IEEE 754 single-precision (s23e8 format): sign bit, 8-bit biased (127) exponent, and 23-bit mantissa. 16-bit floating-point formats use half-precision (s10e5 format): sign bit, 5-bit biased (15) exponent, and 10-bit mantissa.
_SINTTwo's complement signed integer. For example, a 3-bit SINT represents the values -4, -3, -2, -1, 0, 1, 2, 3.
_SNORMSigned normalized integer; which is interpreted in a resource as a signed integer, and is interpreted in a shader as a signed normalized floating-point value in the range [-1, 1]. For an 2's complement number, the maximum value is 1.0f (a 5-bit value 01111 maps to 1.0f), and the minimum value is -1.0f (a 5-bit value 10000 maps to -1.0f). In addition, the second-minimum number maps to -1.0f (a 5-bit value 10001 maps to -1.0f). The resulting integer representations are evenly spaced floating-point values in the range (-1.0f...0.0f), and also a complementary set of representations for numbers in the range (0.0f...1.0f).
_SRGBStandard RGB data, which roughly displays colors in a linear ramp of luminosity levels such that an average observer, under average viewing conditions, can view them on an average display.

All 0's maps to 0.0f, and all 1's maps to 1.0f. The sequence of unsigned integer encodings between all 0's and all 1's represent a nonlinear progression in the floating-point interpretation of the numbers between 0.0f to 1.0f. For more detail, see the SRGB color standard, IEC 61996-2-1, at IEC (International Electrotechnical Commission).

Conversion to or from sRGB space is automatically done by D3DX10 or D3DX9 texture-load functions. If a format with _SRGB has an A channel, the A channel is stored in Gamma 1.0f data; the R, G, and B channels in the format are stored in Gamma 2.2f data.
_TYPELESSTypeless data, with a defined number of bits. Typeless formats are designed for creating typeless resources; that is, a resource whose size is known, but whose data type is not yet fully defined. When a typeless resource is bound to a shader, the application or shader must resolve the format type (which must match the number of bits per component in the typeless format).

A typeless format contains one or more subformats; each subformat resolves the data type. For example, in the R32G32B32 group, which defines types for three-component 96-bit data, there is one typeless format and three fully typed subformats.



    DXGI_FORMAT_R32G32B32_TYPELESS,
    DXGI_FORMAT_R32G32B32_FLOAT,
    DXGI_FORMAT_R32G32B32_UINT,
    DXGI_FORMAT_R32G32B32_SINT,


_UINTUnsigned integer. For instance, a 3-bit UINT represents the values 0, 1, 2, 3, 4, 5, 6, 7.
_UNORMUnsigned normalized integer; which is interpreted in a resource as an unsigned integer, and is interpreted in a shader as an unsigned normalized floating-point value in the range [0, 1]. All 0's maps to 0.0f, and all 1's maps to 1.0f. A sequence of evenly spaced floating-point values from 0.0f to 1.0f are represented. For instance, a 2-bit UNORM represents 0.0f, 1/3, 2/3, and 1.0f.

 

New Resource Formats

Direct3D 10 offers new data compression formats for compressing high-dynamic range (HDR) lighting data, normal maps and heightfields to a fraction of their original size. These compression types include:

  • Shared-Exponent high-dynamic range (HDR) format (RGBE)
  • New Block-Compressed 1-2 channel UNORM/SNORM formats

The block compression formats can be used for any of the 2D or 3D texture types ( Texture2D, Texture2DArray, Texture3D, or TextureCube) including mipmap surfaces. The block compression techniques require texture dimensions to be a multiple of 4 (since the implementation compresses on blocks of 4x4 texels). In the texture sampler, compressed formats are always decompressed before texture filtering.
