L_JP2_BINARYFILTER_BOX

typedef struct _tagL_JP2_BINARYFILTER_BOX 
{ 
   L_UINT32      uStructSize; 
   [L_JP2_UUID_ID](l-jp2-uuid-id.md) FilterType; 
   L_UINT8 *      pData; 
   L_SIZE_T      uDataSize; 
}L_JP2_BINARYFILTER_BOX,   *pL_JP2_BINARYFILTER_BOX;

The L_JP2_BINARYFILTER_BOX structure provides information for a Binary Filter box.

Member	Description
uStructSize	Size of this structure, in bytes. Use the sizeof operator to calculate this value.
FilterType	Filter type. It specifies how the data was transformed before storage. This value is encoded using UUID.
pData	Transformed data.
uDataSize	The size of the transformed data.

Comments

The Binary filter box allows a portion of the file to be further compressed or encoded (i.e. encrypted). This box is defined in JPX and above file formats. A JPEG 2000 file may contain zero or more Binary Filter boxes.
