LNITFFile::SetVector

#include "ltwrappr.h"

L_INT LNITFFile::SetVector(uIndex, pVector)

L_UINT32 uIndex;

/* index of the graphic segment */

LVectorBase * pVector;

/* pointer to LVectorBase class object */

Changes the graphic data in the graphic segment in the NITF file at a specified index.

Parameter

Description

uIndex

A zero-based index of the graphic segment in the NITF file to be changed with the vector data pointed to by pVector.

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.

Returns

SUCCESS

The function was successful.

< 1

An error occurred. Refer to Return Codes.

Comments

To retrieve the object for the graphics data at specified index in the graphic segment, call LNITFFile::GetVector function.
