This class represents a graphic segment in an NITF file. To access the graphic segment of a file, retrieve the GraphicSegment from the NITFReaderManager class.
Graphics segments are not fully supported: no rendering mechanism is provided, only the raw bytes of the segment can be obtained.

Implements Nitf::Segment.
lt_uint8* Nitf::GraphicSegment::getGraphicData | ( | lt_uint32 & | graphicDataLen | ) | const |
This function returns the raw, uninterpreted bytes stored as the payload of the graphics segment.
graphicDataLen | [out] returns the length of the data array |
LT_STATUS Nitf::GraphicSegment::initialize | ( | ) | [virtual] |
This function must be called immediately after the constructor.
Reimplemented from Nitf::Segment.
