Members

dwSize

Size of the structure. This member must be initialized before the structure is used.

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.

Flag	Usage
DDOVER_ADDDIRTYRECT	Add a dirty rectangle to an emulated overlayed surface.
DDOVER_ALPHADEST	Use 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	Use the dwConstAlphaDestfield in the DDOVERLAYFXstructure as the destination alpha channel for this overlay.
DDOVER_ALPHADESTNEG	The NEG suffix indicates that the destination surface becomes more transparent as the alpha value increases.
DDOVER_ALPHADESTSURFACEOVERRIDE	Use the lpDDSAlphaDestfield in the DDOVERLAYFXstructure as the alpha channel destination for this overlay.
DDOVER_ALPHAEDGEBLEND	Use the dwAlphaEdgeBlendfield in the DDOVERLAYFXstructure as the alpha channel for the edges of the image that border the color key colors.
DDOVER_ALPHASRC	Use 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	Use the dwConstAlphaSrcfield in the DDOVERLAYFXstructure as the source alpha channel for this overlay.
DDOVER_ALPHASRCNEG	The NEG suffix indicates that the source surface becomes more transparent as the alpha value increases.
DDOVER_ALPHASRCSURFACEOVERRIDE	Use the lpDDSAlphaSrcfield in the DDOVERLAYFXstructure as the alpha channel source for this overlay.
DDOVER_AUTOFLIP	Autoflip the overlay whenever the video port autoflips.
DDOVER_BOB	Display each field of video port data individually without causing any jittery artifacts.
DDOVER_BOBHARDWARE	Bob is performed using hardware rather than software or emulated.
DDOVER_DDFX	Use the overlay FX flags to define special overlay FX.
DDOVER_HIDE	Turn this overlay off.
DDOVER_INTERLEAVED	Indicates that the surface memory is composed of interleaved fields.
DDOVER_KEYDEST	Use the color key associated with the destination surface.
DDOVER_KEYDESTOVERRIDE	Use the dckDestColorkeyfield in the DDOVERLAYFXstructure as the color key for the destination surface.
DDOVER_KEYSRC	Use the color key associated with the source surface.
DDOVER_KEYSRCOVERRIDE	Use the dckSrcColorkeyfield in the DDOVERLAYFXstructure as the color key for the source surface.
DDOVER_OVERRIDEBOBWEAVE	Indicates that bob/weave decisions should not be overridden by other interfaces.
DDOVER_REFRESHALL	Redraw the entire surface on an emulated overlayed surface.
DDOVER_REFRESHDIRTYRECTS	Redraw all dirty rectangles on an emulated overlayed surface.
DDOVER_SHOW	Turn this overlay on.

rgjunc

lpVideoPort

Pointer to a DDRAWI_DDVIDEOPORT_LCLstructure of the video port currently writing data to this surface.

lpddOverlayFX

Pointer to a DDOVERLAYFXstructure that contains the current overlay FX.

ddsCapsEx

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

dwTextureStage

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