  • lpIUnknowns**
    This member is used by DirectDraw and should not be filled in by the driver.

  • lpDD_lcl
    This member is used by DirectDraw and should not be filled in by the driver.

  • dwPageLockCount**
    This member is used by DirectDraw and should not be filled in by the driver.

  • dwBytesAllocated**
    This member is used by DirectDraw and should not be filled in by the driver.

  • lpDD_int**
    This member is used by DirectDraw and should not be filled in by the driver.

  • dwMipMapCount**
    Contains the number of mipmap levels in the chain.

  • lpDDIClipper**
    This member is used by DirectDraw and should not be filled in by the driver.

  • lpHeapAliasInfo**
    This member is used by DirectDraw and should not be filled in by the driver.

  • dwOverlayFlags**
    Contains the overlay flags most recently passed to UpdateOverlay.

    The following table shows the possible flags.

    Flag Description
    DDOVER_ADDDIRTYRECT Adds a dirty rectangle to an emulated overlayed surface.
    DDOVER_ALPHADEST Uses the alpha information in the pixel format or the alpha channel surface attached to the destination surface as the alpha channel for the destination overlay.
    DDOVER_ALPHADESTCONSTOVERRIDE Uses the dwConstAlphaDest field in the DDOVERLAYFX structure as the destination alpha channel for this overlay.
    DDOVER_ALPHADESTNEG Indicates that the destination surface becomes more transparent as the alpha value increases.
    DDOVER_ALPHADESTSURFACEOVERRIDE Uses the lpDDSAlphaDest field in the DDOVERLAYFX structure as the alpha channel destination for this overlay.
    DDOVER_ALPHAEDGEBLEND Uses the dwAlphaEdgeBlend field in the DDOVERLAYFX structure as the alpha channel for the edges of the image that border the color key colors.
    DDOVER_ALPHASRC Uses the alpha information in the pixel format or the alpha channel surface attached to the source surface as the source alpha channel for this overlay.
    DDOVER_ALPHASRCCONSTOVERRIDE Uses the dwConstAlphaSrc field in the DDOVERLAYFX structure as the source alpha channel for this overlay.
    DDOVER_ALPHASRCNEG Indicates that the source surface becomes more transparent as the alpha value increases.
    DDOVER_ALPHASRCSURFACEOVERRIDE Uses the lpDDSAlphaSrc field in the DDOVERLAYFX structure as the alpha channel source for this overlay.
    DDOVER_AUTOFLIP Autoflips the overlay whenever the video port autoflips.
    DDOVER_BOB Displays each field of video port data individually without causing jittery artifacts.
    DDOVER_BOBHARDWARE Indicates that hardware, not software or emulation, performs a bob operation.
    DDOVER_DDFX Uses the overlay FX flags to define special overlay FX.
    DDOVER_HIDE Turns this overlay off.
    DDOVER_INTERLEAVED Indicates that the surface memory is composed of interleaved fields.
    DDOVER_KEYDEST Uses the color key associated with the destination surface.
    DDOVER_KEYDESTOVERRIDE Uses the dckDestColorkey field in the DDOVERLAYFX structure as the color key for the destination surface.
    DDOVER_KEYSRC Uses the color key associated with the source surface.
    DDOVER_KEYSRCOVERRIDE Uses the dckSrcColorkey field in the DDOVERLAYFX structure as the color key for the source surface.
    DDOVER_OVERRIDEBOBWEAVE Indicates that bob and weave operations should not be overridden by other interfaces.
    DDOVER_REFRESHALL Redraws the entire surface on an emulated overlayed surface.
    DDOVER_REFRESHDIRTYRECTS Redraws all dirty rectangles on an emulated overlayed surface.
    DDOVER_SHOW Turns this overlay on.
