Not supported in Windows Embedded CE.
- D3DMFMT_P8
Not supported in Windows Embedded CE.
- D3DMFMT_A8
8-bit alpha only.
- D3DMFMT_UYVY
UYVY format (PC98 compliance).
- D3DMFMT_YUY2
YUY2 format (PC98 compliance).
- D3DMFMT_DXT1
DXT1 compression texture format.
- D3DMFMT_DXT2
DXT2 compression texture format.
- D3DMFMT_DXT3
DXT3 compression texture format.
- D3DMFMT_DXT4
DXT4 compression texture format.
- D3DMFMT_DXT5
DXT5 compression texture format.
- D3DMFMT_D32
32-bit z-buffer bit depth.
- D3DMFMT_D15S1
16-bit z-buffer bit depth where 15 bits are reserved for the depth channel and 1 bit is reserved for the stencil channel.
- D3DMFMT_D24S8
32-bit z-buffer bit depth where 24 bits are reserved for the depth channel and 8 bits are reserved for the stencil channel.
- D3DMFMT_D16
16-bit z-buffer bit depth.
- D3DMFMT_D24X8
32-bit z-buffer bit depth where 24 bits are reserved for the depth channel.
- D3DMFMT_D24X4S4
32-bit z-buffer bit depth where 24 bits are reserved for the depth channel and 4 bits are reserved for the stencil channel.
- D3DMFMT_INDEX16
16-bit index buffer bit depth.
- D3DMFMT_INDEX32
32-bit index buffer bit depth.
- D3DMFMT_VERTEXDATA
Describes a vertex buffer surface.
- D3DMFMT_D3DMVALUE_FLOAT
Indicates that a D3DMVALUE is defined to be an IEEE 32-bit single precision floating point value.
- D3DMFMT_D3DMVALUE_FIXED
Indicates that a D3DMVALUE is defined as a 16.16 fixed point value. In this instance, 16.16 fixed point is defined to mean there is one sign bit, 15 bits of integer data, and 16 bits of fractional data.
- D3DMFMT_NUMFORMAT
Identifies the number of formats in the D3DMFORMAT enumeration. You can use this enumeratoin element as the upper bound to loop through all the elements of the enumeration.
- D3DMFMT_FORCE_ULONG
Forces the compiler to interpret the enumeration as a ULONG value. This value is not used directly in Direct3D Mobile programming.
Remarks
The following table describes the naming convention for the elements of D3DMFORMAT.
| Character | Description |
|---|---|
A |
The number of bits for the alpha component. |
R |
The number of bits for the red color component. |
G |
The number of bits for the green color component. |
B |
The number of bits for the blue color component. |
X |
The number of unused bits. |
P |
The number of bits for palletized colors. |
S |
The number of stencil bits. |
D |
The umber of depth bits. |
The characters in the element names are organized so the most significant bits are first. For example, D3DMFMT_A8P8 indicates that the high byte of this two-byte format is alpha.
For formats relating to depth and stencil buffers, the element naming does not indicate a particular bit order per pixel. These formats are also not lockable by applications. Drivers can consume more than the indicated number of bits per depth channel, but not more than the indicated number of bits per stencil channel.
Render target formats are restricted to D3DMFMT_X1R5G5B5, D3DMFMT_R5G6B5, D3DMFMT_X8R8G8B8, and D3DMFMT_A8R8G8B8.
Pixel formats are denoted by opaque DWORD identifiers. The format of these DWORDs has been chosen to enable the expression of IHV-defined extension formats, and also to include the well-established FOURCC method. The set of formats understood by the Microsoft® Direct3D Mobile® middleware is defined by D3DMFORMAT.
Note that IHV-supplied formats and many FOURCC codes are not listed in the D3DMFORMAT enumeration. The formats in this enumeration are unique in that they are sanctioned by the middleware, meaning that the reference driver operates on all these types. The IHV-supplied formats are supported by individual IHVs on a card-by-card basis.
