PFND3D10DDI_SETTEXTFILTERSIZE callback function

The SetTextFilterSize function sets the width and height of the monochrome convolution filter.

Syntax

PFND3D10DDI_SETTEXTFILTERSIZE Pfnd3d10ddiSettextfiltersize;

void Pfnd3d10ddiSettextfiltersize(
  D3D10DDI_HDEVICE Arg1,
  UINT Arg2,
  UINT Arg3
)
{...}

Parameters

Arg1

hDevice [in]

A handle to the display device (graphics context).

Arg2

Width [in]

The width of the monochrome convolution filter. The width can be from 1 to 7 texels.

Arg3

Height [in]

The height of the monochrome convolution filter. The height can be from 1 to 7 texels.

Return value

None

Remarks

The driver can use the pfnSetErrorCb callback function to set an error code.

The number of samples that are required from a kernel's dimensions is actually (Width + 1) x (Height + 1), which can come out to from 4 to 64 samples. These settings apply across all samplers that are configured to use the D3D10_DDI_FILTER_TEXT_1BIT filter from the D3D10_DDI_FILTER enumeration.

SetTextFilterSize ensures that values that are supplied in the Width and Height parameters are in range. The default vaules for Width and Height are both 1, initially. The driver must set these default values during device creation.

The driver should not encounter any error, except for D3DDDIERR_DEVICEREMOVED. Therefore, if the driver passes any error, except for D3DDDIERR_DEVICEREMOVED, in a call to the pfnSetErrorCb function, the Direct3D runtime will determine that the error is critical. Even if the device was removed, the driver is not required to return D3DDDIERR_DEVICEREMOVED. However, if device removal interfered with the operation of SetTextFilterSize (which typically should not happen), the driver can return D3DDDIERR_DEVICEREMOVED.
