The L_JP2_IMAGEINFO_ELEMENT structure provides one type of information about all boxes of the same type within one JPEG 2000 file.

Member	Description
uStructSize	Size of this structure, in bytes. Use the sizeof operator to calculate this value.
uNumOfBoxes	Number of boxes. This field specifies the size of pBoxOffset array, pBoxSize array, pBoxDataOffset array, and pBoxDataSize array
pBoxOffset	Box start offset array. It specifies the offset in bytes to the start byte of the box and it is relative to the first byte of the file.
pBoxSize	Box size in bytes.
pBoxDataOffset	Box data start offset array. It specifies the offset in bytes to the start byte of the box data and it is relative to the first byte of the file.
pBoxDataSize	Box data size in bytes.

Comments

The L_JP2_IMAGEINFO_ELEMENT structure provides information for one of JPEG 2000 box©s type. This structure is use with the L_Jp2GetFileInfo function. It provides information about the number of boxes exist in the file of that type, start offsets, and data sizes.
