L_INT LNITFFile::GetTextHeader(uIndex, pTxtHeader)
Retrieves the text header information of a specific text segment.
A zero-based index of the text segment in the NITF file.
Pointer to a TXTHEADER structure to be updated with the text header information of the specified text segment at the index uIndex.
Value | Meaning |
---|---|
SUCCESS | The function was successful. |
< 1 | An error occurred. Refer to Return Codes. |
To retrieve the number of the text segments available in the NITF file, call the LNITFFile::GetTextHeaderCount function.
To change the text header information for a specific text segment, call the LNITFFile::SetTextHeader function.
