DXSAMPLEFORMATENUM enumeration

  • Article

Indicates the pixel format of a DXSurface object. This enumerated type is returned by the IDXARGBReadPtr::GetNativeType and IDXSurface::GetPixelFormat methods.

Constants

  • DXPF_FLAGSMASK
    Mask that specifies which bits of the longword are used to indicate transparency and dithering options.

  • DXPF_NONPREMULT
    Flag that indicates that the pixel format is not alpha premultiplied.

  • DXPF_TRANSPARENCY
    Flag that indicates that the surface uses a color keys for transparency.

  • DXPF_TRANSLUCENCY
    Flag that indicates that the pixel format uses 8-bit alpha values.

  • DXPF_2BITERROR
    Flag that indicates that the surface uses a 2-bit error term for dithering.

  • DXPF_3BITERROR
    Flag that indicates that the surface uses a 3-bit error term for dithering.

  • DXPF_4BITERROR
    Flag that indicates that the surface uses a 4-bit error term for dithering.

  • DXPF_5BITERROR
    Flag that indicates that the surface uses a 5-bit error term for dithering.

  • DXPF_ERRORMASK
    Mask of all bits used for dithering.

  • DXPF_NONSTANDARD
    Flag that indicates that the surface pixel format is not one of the formats listed here. This flag can be combined with DXPF_NONPREMULT, if operations on the surface are more efficient with a pixel format that is not alpha premultiplied.

  • DXPF_PMARGB32
    A 32-bit pixel format, with eight bits each of alpha, red, green, and blue. The bits are stored in this order, with the alpha stored in the higher-order bits and the blue in the lower-order bits. For this format, the color values are alpha premultiplied.

  • DXPF_ARGB32
    A 32-bit pixel format, with eight bits each of alpha, red, green, and blue. The bits are stored in this order, with the alpha stored in the higher-order bits and the blue in the lower-order bits.

  • DXPF_ARGB4444
    A 16-bit pixel format, with four bits each of alpha, red, green, and blue.

  • DXPF_A8
    An 8-bit pixel format that stores only alpha values.

  • DXPF_RGB32
    A 32-bit pixel format, with eight bits each of red, green, and blue. This is essentially a 24-bit version of DXPF_ARGB32, with no alpha values.

  • DXPF_RGB24
    A 24 bit pixel format, with eight bits each of red, green, and blue.

  • DXPF_RGB565
    A 16-bit pixel format that uses five bits for red, six bits for green, and five bits for blue.

  • DXPF_RGB555
    A 16-bit pixel format that uses five bits for red, five bits for green, and five bits for blue. The highest-order bit is ignored.

  • DXPF_RGB8
    An 8-bit pixel format, where each value refers to a color in a palette.

  • DXPF_ARGB1555
    A 16-bit pixel format that uses five bits for red, five bits for green, and five bits for blue. The last bit is used to flag a pixel as transparent.

  • DXPF_RGB32_CK
    Same format as DXPF_RGB32 and uses a color key for transparency.

  • DXPF_RGB24_CK
    Same format as DXPF_RGB24 and uses a color key for transparency.

  • DXPF_RGB555_CK
    Same format as DXPF_RGB555 and uses a color key for transparency.

  • DXPF_RGB565_CK
    Same format as DXPF_RGB565 and uses a color key for transparency.

  • DXPF_RGB8_CK
    Same format as DXPF_RGB8 and uses a color key for transparency.

Remarks

You can use the mask to determine the pixel format of the IDXSurface and any dithering or transparency options used for rendering.
