| org.geotools.referencing.operation.transform.WarpAdapter
| WarpAdapter | | final class WarpAdapter extends Warp (Code) | | Wraps an arbitrary
MathTransform2D into an image warp operation.
This warp operation is used by
org.geotools.coverage.processing.operation.Resample when no standard warp operation has been found applicable.

| Constructor Summary | |
| public | WarpAdapter(CharSequence name, MathTransform2D inverse)
Constructs a new
WarpAdapter using the given transform.
Parameters:
name - The coverage name. |
| Method Summary | |
| public MathTransform2D | getTransform()
Returns the transform from image's destination pixels to source pixels. | | public Point2D | mapDestPoint(Point2D destPt)
Computes the source point corresponding to the supplied point. | | public Point2D | mapSourcePoint(Point2D sourcePt)
Computes the destination point corresponding to the supplied point. | | public float[] | warpSparseRect(int xmin, int ymin, int width, int height, int periodX, int periodY, float[] destRect)
Computes the source pixel positions for a given rectangular
destination region, subsampled with an integral period. |
| WarpAdapter | | public WarpAdapter(CharSequence name, MathTransform2D inverse)(Code) | | Constructs a new
WarpAdapter using the given transform.
Parameters:
name - The coverage name. Used for formatting error message.
Parameters:
inverse - The inverse of the transformation to apply for projectingan image. This inverse transform maps destination pixels to source pixels. |
| getTransform | | public MathTransform2D getTransform()(Code) | | Returns the transform from image's destination pixels to source pixels.
|
| mapDestPoint | | public Point2D mapDestPoint(Point2D destPt)(Code) | | Computes the source point corresponding to the supplied point.
Parameters:
destPt - The position in destination image coordinatesto map to source image coordinates. |
| mapSourcePoint | | public Point2D mapSourcePoint(Point2D sourcePt)(Code) | | Computes the destination point corresponding to the supplied point.
Parameters:
sourcePt - The position in source image coordinatesto map to destination image coordinates. |
| warpSparseRect | | public float[] warpSparseRect(int xmin, int ymin, int width, int height, int periodX, int periodY, float[] destRect)(Code) | | Computes the source pixel positions for a given rectangular
destination region, subsampled with an integral period.
