L_INT LNITFFile::SetVector(uIndex, pVector)
A zero-based index of the graphic segment in the NITF file to be changed with the vector data pointed to by pVector.
Pointer LVectorBase class object references the new 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 retrieve the object for the graphics data at specified index in the graphic segment, call LNITFFile::GetVector function.
