WIA_DITHER_PATTERN_DATA structure (wia_xp.h)

The WIA_DITHER_PATTERN_DATA structure specifies a dither pattern for scanners. It is used in conjunction with the scanner device property constant WIA_DPS_DITHER_PATTERN_DATA.

Syntax

typedef struct _WIA_DITHER_PATTERN_DATA {
  LONG lSize;
  BSTR bstrPatternName;
  LONG lPatternWidth;
  LONG lPatternLength;
  LONG cbPattern;
  BYTE *pbPattern;
} WIA_DITHER_PATTERN_DATA, *PWIA_DITHER_PATTERN_DATA;
