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. This function is available in the Document Toolkit.

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.
