public class TLcdOrthographicRasterReferencer extends java.lang.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|
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.
|Modifier and Type||Method and Description|
Creates a raster reference for an image of a given size, based on pairs of tie points.
public TLcdOrthographicRasterReferencer(ILcdRasterReferencer aRasterReferencer)
public ILcdRasterReference createRasterReference(int aImageWidth, int aImageHeight, ILcdPoint aImageTiePoints, ILcdModelReference aModelReference, ILcdPoint aModelTiePoints, ILcdPoint aMappedModelTiePointsSFCT)
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.
