SetPixelShader routine

The SetPixelShader function sets a pixel shader to be used in all drawing operations.

Syntax


PFND3DDDI_SETPIXELSHADER SetPixelShader;

__checkReturn HRESULT APIENTRY SetPixelShader(
  _In_  HANDLE hDevice,
  _In_  HANDLE hShaderHandle
)
{ ... }

Parameters

hDevice [in]

A handle to the display device (graphics context).

hShaderHandle [in]

A handle to the pixel shader code object.

Return value

SetPixelShader returns S_OK or an appropriate error result if the pixel shader is not successfully set.

Remarks

All subsequent drawing operations use the given shader until another is selected.

For user-mode display drivers that support pixel shaders before version 2.0, the Microsoft Direct3D runtime passes 0 in the hShaderHandle parameter to indicate a fixed-function pipeline. For user-mode display drivers that support pixel shader version 2.0 or later, the runtime converts Direct3D fixed-function pixel state to pixel shader version 2.0. For more information about fixed-function state, see Converting the Direct3D Fixed-Function State.

Requirements

Version

Available in Windows Vista and later versions of the Windows operating systems.
