The D3DKMDT_PIXEL_VALUE_ACCESS_MODE enumeration is used to indicate the way color values or palette indices are stored in the primary surface of a video present source.

Syntax

typedef enum _D3DKMDT_PIXEL_VALUE_ACCESS_MODE {
  D3DKMDT_PVAM_UNINITIALIZED,
  D3DKMDT_PVAM_DIRECT,
  D3DKMDT_PVAM_PRESETPALETTE,
  D3DKMDT_PVAM_SETTABLEPALETTE
} D3DKMDT_PIXEL_VALUE_ACCESS_MODE;

Constants

D3DKMDT_PVAM_UNINITIALIZED Indicates that a variable of type D3DKMDT_PIXEL_VALUE_ACCESS_MODE has not yet been assigned a meaningful value.
D3DKMDT_PVAM_DIRECT Indicates that colors are stored directly in the primary surface.
D3DKMDT_PVAM_PRESETPALETTE Indicates that palette indices are stored in the primary surface. Colors are stored in a palette that is specific to the display adapter. The operating system can query the display miniport driver for the palette.
D3DKMDT_PVAM_SETTABLEPALETTE Indicates that palette indices are stored in the primary surface. Colors are stored in a palette that the operating system can set dynamically by calling the display miniport driver.
