Detailed Description

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.

Definition at line 37 of file GraphicSegment.h.

Member Function Documentation

LT_STATUS Nitf::GraphicSegment::addMetadataLocal ( LTIMetadataDatabase db) const
virtual

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.

Parameters
graphicDataLen[out] returns the length of the data array
Returns
the data, as a byte array
LT_STATUS Nitf::GraphicSegment::initialize ( )
virtual

This function must be called immediately after the constructor.

Returns
success or failure

Reimplemented from Nitf::Segment.
