L_JP2_BINARYFILTER_BOX (original) (raw)

Summary

The L_JP2_BINARYFILTER_BOX structure provides information for a Binary Filter box.

Syntax

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

Members

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.

The structure is used by:

• L_Jp2ReadBox
• L_Jp2AppendBoxes
• L_Jp2ReadBoxMemory
• L_Jp2AppendBoxesMemory
• L_Jp2FreeBoxes
• L_Jp2SetBoxes
• L_Jp2GetBoxes
