Parameter |
Description |
hJp2 |
JPEG 2000 engine handle that was created by the L_Jp2Create function. |
pszFile |
Character string that contains the name of the file to append boxes. |
uBoxType |
The type of the boxes to be appended. |
pBoxes |
Point to an array of boxes of type uBoxType. |
uNumOfBoxes |
Number of boxes in the array. |
Returns
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
Comments
This function appends JPEG 2000 boxes to the specified file. If the specified box type is L_JP2_IPR, L_JPX_IPR, L_JPX_GTSO, or L_JPX_COMPOSITION, only the first box will be appended, because a JPEG 2000 file cannot have more than one box each of these types. Boxes of type uBoxType will be reset and updated with the new appended boxes only.
