Indicates how pixel shader sampling will be restricted.
Syntax
typedef enum D2D1_PIXEL_OPTIONS {
D2D1_PIXEL_OPTIONS_NONE = 0,
D2D1_PIXEL_OPTIONS_TRIVIAL_SAMPLING = 1,
D2D1_PIXEL_OPTIONS_FORCE_DWORD = 0xffffffff
} ;
Constants
D2D1_PIXEL_OPTIONS_NONEValue: 0 The pixel shader is not restricted in its sampling. |
D2D1_PIXEL_OPTIONS_TRIVIAL_SAMPLINGValue: 1 The pixel shader samples inputs only at the same scene coordinate as the output pixel and returns transparent black whenever the input pixels are also transparent black. |
D2D1_PIXEL_OPTIONS_FORCE_DWORDValue: 0xffffffff |
Remarks
If the shader specifies D2D1_PIXEL_OPTIONS_NONE, it must still correctly implement the region of interest calculations in ID2D1Transform::MapOutputRectToInputRects and ID2D1Transform::MapInputRectsToOutputRect.
