L_LTNTF_API L_INT L_NITFSetVectorHandle(hNitf, uIndex, pVector)
Sets the handle for the graphic data in the graphic segment in the NITF file at a specified index.
Handle to an existing NITF file, created by calling the L_NITFCreate function.
A zero-based index of the graphic segment in the hNitf handle to be set with the vector handle pointed to by pVector.
Pointer to a vector handle references the graphic data to set in the graphic segment in the NITF file at the specified index uIndex.
| Value | Meaning |
|---|---|
| SUCCESS | The function was successful. |
| < 1 | An error occurred. Refer to Return Codes. |
To get the handle for the graphics data at specified index in the graphic segment, call L_NITFGetVectorHandle function.
