Class TLcdProjectiveRasterReferencer
 All Implemented Interfaces:
ILcdRasterReferencer
The referencer returns an ILcdRasterReference
whose model
reference is an ILcdGridReference
. The projection of this
ILcdGridReference
is a
TLcdRectifiedProjectiveProjection
.
If the initial reference of the model tie points is also an
ILcdGridReference
, then the newly created grid reference will
have exactly the same parameters, except that the initial projection is
wrapped inside the rectified projection. Thus, you can consider the new
reference system as being equivalent to the original reference, but slightly
adjusted to match the tie points.
If the initial reference of the model tie points is an
ILcdGeoReference
, then the newly created grid reference will
be a ILcdGridReference
with the same geodetic datum.

createRasterReference
public ILcdRasterReference createRasterReference(int aImageWidth, int aImageHeight, ILcdPoint[] aImageTiePoints, ILcdModelReference aModelReference, ILcdPoint[] aModelTiePoints, ILcdPoint[] aMappedModelTiePointsSFCT) Description copied from interface:ILcdRasterReferencer
Creates a raster reference for an image of a given size, based on pairs of tie points.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.
 Specified by:
createRasterReference
in interfaceILcdRasterReferencer
 Parameters:
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 benull
, if the mapped points are not required. Returns:
 a raster reference containing a new model reference and raster bounds that try to satisfy the given tie points.
