WIA_PATCH_CODES structure

The WIA_PATCH_CODES structure stores header information for the patch code metadata report of one scan job (one call to IWiaMiniDrv::drvAcquireItemData).

Syntax

C++


typedef struct _WIA_PATCH_CODES {
  DWORD                Tag;
  DWORD                Version;
  DWORD                Size;
  DWORD                Count;
  WIA_PATCH_CODES_INFO PatchCodes[1];
} WIA_PATCH_CODES;

Members

Tag: Must be the literal 'WBAT', 4 single byte ASCII characters.
Version: Must be the value 0x00010000 (Version 1.0).
Size: The complete size of this WIA_PATCH_CODES header structure, in bytes, including the complete size of the WIA_PATCH_CODES_INFO list.
Count: Specifies the number of WIA_PATCH_CODES_INFO elements in the PatchCodes sequence.
PatchCodes: Placeholder for a sequence of Count contiguous WIA_PATCH_CODES_INFO structures.

Remarks

The header must be followed by a sequence of patch code information structures, one for each detected patch code, in the order the patch codes were found and decoded.
