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.
