public class TLcdOrthographicRasterReferencer extends Object implements ILcdRasterReferencer
If the given model reference is not a geodetic reference, the reference and the tie points are left unchanged.
This class is useful to avoid having to perform rectification in geodetic references, which is generally ill-advised due to distortion and wrap-around.

Constructor and Description |

TLcdOrthographicRasterReferencer(ILcdRasterReferencer aRasterReferencer)
Creates a new TLcdOrthographicRasterReferencer that will delegate the
computation of raster references to the given ILcdRasterReferencer,
after having transformed geodetic coordinates to orthographic grid
references.

ILcdRasterReferencer
An optional array can be provided for obtaining the model tie points transformed to image coordinates on return. These reflect the effects of the referencing. The differences between the transformed model tie points (expressed in pixels) and the original image tie points (also expressed in pixels) provide a measure for the success of the referencing. With a perfect raster reference, the resulting model tie points correspond to the original image tie points.

aImageWidth
- the image width of the raster, expressed
in pixels.aImageHeight
- the image height of the raster, expressed
in pixels.aImageTiePoints
- the image tie points, expressed in pixels.aModelReference
- the reference of the model tie points.aModelTiePoints
- the model tie points corresponding to the
image tie points, expressed in model
coordinates.aMappedModelTiePointsSFCT
- an optional array for obtaining the
the model tie points mapped to image
coordinates upon return. This parameter
may be null
, if the mapped
points are not required.
