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.
