This class defines a CADRG frame as described in the CADRG table of contents.
Library: ilvmaps
A frame corresponds physically to a file in a CADRG product. It can be loaded with an IlvCADRGFrameReader
.
Most of the frames are georeferenced, except for those used to display the overview of a CADRG product or the map legends. Instances of IlvCADRGFrame
are obtained with an IlvCADRGCoverage
.
makeReader()
. IlShort IlvCADRGFrame::getColumn | ( | ) | const |
Returns the column of the frame in its CADRG coverage.
const IlvCADRGCoverage* IlvCADRGFrame::getCoverage | ( | ) | const |
Returns the IlvCADRGCoverage
that owns the frame.
IlvCADRGCoverage
that should not be modified nor deleted. const char* IlvCADRGFrame::getFileName | ( | ) | const |
Returns the file name of the frame as read from the CADRG table of contents.
getPathName()
, IlvCADRGTocReader
. IlBoolean IlvCADRGFrame::getLowerRightCorner | ( | IlvCoordinate & | lr | ) | const |
Queries the lower-right corner of the frame region.
The frame projection is either an IlvGeographicProjection
or, for polar regions, an IlvAzimuthalEquidistantProjection
.
lr | Set on return to the coordinates of the lower-right corner of the frame. |
IlTrue
if the frame is georeferenced. Otherwise, it returns IlFalse
, and the value of lr should not be used. This occurs in the case of legend frames or of overview frames. const char* IlvCADRGFrame::getPathName | ( | ) | const |
Returns the path name of the frame as read from the CADRG table of contents. The path name is relative to the directory that contains the CADRG table of contents.
"A.TOC"
. getPathName()
, IlvCADRGTocReader
. IlShort IlvCADRGFrame::getRow | ( | ) | const |
Returns the row of the frame in its CADRG coverage.
IlBoolean IlvCADRGFrame::getUpperLeftCorner | ( | IlvCoordinate & | ul | ) | const |
Queries the upper-left corner of the frame region.
The frame projection is either an IlvGeographicProjection
or, for polar regions, an IlvAzimuthalEquidistantProjection
.
ul | Set on return to the coordinates of the upper-left corner of the frame. |
IlTrue
if the frame is georeferenced. Otherwise, it returns IlFalse
, and the value of ul should not be used. This occurs in the case of legend frames or of overview frames. IlvCADRGFrameReader* IlvCADRGFrame::makeReader | ( | ) | const |
Initializes a frame reader for the CADRG frame.
0
if the reader initialization failed, or an IlvCADRGFrameReader
instance that must be deleted. © Copyright 2016, Rogue Wave Software, Inc. All Rights Reserved.
