D3DHAL_DP2SETPALETTE structure

The D3DHAL_DP2SETPALETTE structure is used to associate a palette with a texture when a driver responds to D3DDP2OP_SETPALETTE in D3dDrawPrimitives2. This opcode is used to map an association between a palette handle and a surface handle, and specify the characteristics of the palette.

Syntax

typedef struct _D3DHAL_DP2SETPALETTE {
  DWORD dwPaletteHandle;
  DWORD dwPaletteFlags;
  DWORD dwSurfaceHandle;
} D3DHAL_DP2SETPALETTE;

Members

dwPaletteHandle

Specifies a handle to the palette to be set up. If the value is zero, the surface specified by dwSurfaceHandle should be uncoupled from any palette it might have been associated with previously.

dwPaletteFlags

Specifies a set of flags that specify the attributes of the palette. |Flag|Meaning| |--- |--- | |DDRAWIPAL_2|The palette has 2 entries. Currently unused.| |DDRAWIPAL_4|The palette has 4 entries. Currently unused.| |DDRAWIPAL_16|The palette has 16 entries. Currently unused.| |DDRAWIPAL_256|The palette has 256 entries. Currently unused.| |DDRAWIPAL_ALLOW256|The palette can be fully updated. Currently unused.| |DDRAWIPAL_ALPHA|The palette's alpha data channel is valid and should be used.| |DDRAWIPAL_DIRTY|The palette has been changed so the GDI palette is out of sync. Currently unused.| |DDRAWIPAL_EXCLUSIVE|The palette is being used in exclusive mode. Currently unused.| |DDRAWIPAL_GDI|The palette is allocated through GDI. Currently unused.| |DDRAWIPAL_INHEL|The palette is done in the HEL (hardware emulation layer). Currently unused.| |DDRAWIPAL_STORED_8|The palette is stored using 8 bpp per entry. Currently unused.| |DDRAWIPAL_STORED_16|The palette is stored using 16 bpp per entry. Currently unused.| |DDRAWIPAL_STORED_24|The palette is stored using 24 bpp per entry. Currently unused.| |DDRAWIPAL_STORED_8INDEX|The palette is stored as an 8-bit index into a destination palette. Currently unused.|

dwSurfaceHandle

Specifies a handle to the Direct3D surface (texture) that this palette (identified by dwPaletteHandle) is associated to.

Remarks

The number of D3DHAL_DP2SETPALETTE structures to follow is specified by the wStateCount member of the D3DHAL_DP2COMMAND structure that precedes them in the command stream.
