LNITFFile::GetVector
#include "ltwrappr.h"
LVectorBase * LNITFFile::GetVector(uIndex)
L_UINT32 uIndex; |
/* index of the graphics data */ |
Retrieves an LVectorBase class object as the for the graphics data at a specified index in the graphic segment. This function is available in the Document Toolkit.
Parameter |
Description |
uIndex |
A zero-based index of the graphic data in the NITF file. |
Returns
! NULL |
The function was successful and an LVectorBase class object will be returned. |
NULL |
An error occurred. |
Comments
To change the graphic data in the graphic segment in the NITF file at specified index, call the LNITFFile::SetVector function.
When the returned LVectorBase class object is no longer needed, it should be freed by calling LVectorBase::Free function.
For every successful call to LNITFFile::GetVector, there must be a call to LVectorBase::Free to free this returned LVectorBase class object.
