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. |
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
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.
This function does not append L_JP2_RESOLUTION_BOX box it returns ERROR_INV_PARAMETER error, this box can be set by L_Jp2SetBoxes.
