D3DDDIARG_SETCONVOLUTIONKERNELMONO structure (d3dumddi.h)

  • Article

The D3DDDIARG_SETCONVOLUTIONKERNELMONO structure describes parameters for setting the monochrome convolution kernel.

Syntax

typedef struct _D3DDDIARG_SETCONVOLUTIONKERNELMONO {
  [in] UINT  Width;
  [in] UINT  Height;
  [in] FLOAT *pKernelRow;
  [in] FLOAT *pKernelCol;
} D3DDDIARG_SETCONVOLUTIONKERNELMONO;

Members

[in] Width

The width, which is the resolution of the filter kernel in the horizontal direction. Valid values for this member are from 1 to 7.

[in] Height

The height, which is the resolution of the filter kernel in the vertical direction. Valid values for this member are from 1 to 7.

[in] pKernelRow

A pointer to weights in the horizontal direction of a separable filter. In Microsoft Direct3D 9.L and later, pKernelRow must be NULL, which indicates that all of the weights are 1.0.

[in] pKernelCol

A pointer to weights in the vertical direction of a separable filter. In Direct3D 9.L and later, pKernelCol must be NULL, which indicates that all of the weights are 1.0.
