L_NITFSetVectorHandle

#include "ltntf.h"

L_LTNTF_API L_INT L_NITFSetVectorHandle(hNitf, uIndex, pVector)

HNITF hNitf;

handle to an existing NITF file

L_UINT32 uIndex;

index of the graphic segment

pVECTORHANDLE pVector;

pointer to a vector handle

Sets the handle for the graphic data in the graphic segment in the NITF file at a specified index.

Parameter

Description

hNitf

Handle to an existing NITF file, created by calling the L_NITFCreate function.

uIndex

A zero-based index of the graphic segment in the hNitf handle to be set with the vector handle pointed to by pVector.

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.

Returns

SUCCESS

The function was successful.

< 1

An error occurred. Refer to Return Codes.

Comments

To get the handle for the graphics data at specified index in the graphic segment, call L_NITFGetVectorHandle function.
