Static Methods

createFromBaseLines(
Coordinate src0, Coordinate src1, Coordinate dest0, Coordinate dest1) → AffineTransformation -
- Creates an AffineTransformation defined by a mapping between two baselines.
- The computed transformation consists of:
-
- a translation
- from the start point of the source baseline to the start point of the destination baseline,
- a rotation through the angle between the baselines about the destination start point,
- and a scaling equal to the ratio of the baseline lengths.
- If the source baseline has zero length, an identity transformation is returned.
- @param src0 the start point of the source baseline
- @param src1 the end point of the source baseline
- @param dest0 the start point of the destination baseline
- @param dest1 the end point of the destination baseline
- @return the computed transformation
-
- Creates an AffineTransformation defined by a mapping between two baselines.
-
createFromControlVectors(
Coordinate? src0, Coordinate? dest0) → AffineTransformation -
- Creates an AffineTransformation defined by a single control vector. A
- control vector consists of a source point and a destination point, which is
- the image of the source point under the desired transformation. This
- produces a translation.
- @param src0
-
the start point of the control vector
- @param dest0
-
the end point of the control vector
- @return the computed transformation
- Creates an AffineTransformation defined by a single control vector. A
-
createFromControlVectors2(
Coordinate src0, Coordinate src1, Coordinate dest0, Coordinate dest1) → AffineTransformation? -
- Creates an AffineTransformation defined by a pair of control vectors. A
- control vector consists of a source point and a destination point, which is
- the image of the source point under the desired transformation. The
- computed transformation is a combination of one or more of a uniform scale,
- a rotation, and a translation (i.e. there is no shear component and no
- reflection)
- @param src0
- @param src1
- @param dest0
- @param dest1
- @return the computed transformation, or null if the control vectors do not determine a well-defined transformation
- Creates an AffineTransformation defined by a pair of control vectors. A
-
createFromControlVectors3(
Coordinate src0, Coordinate src1, Coordinate src2, Coordinate dest0, Coordinate dest1, Coordinate dest2) → AffineTransformation? -
- Creates a transformation from a set of three control vectors. A control
- vector consists of a source point and a destination point, which is the
- image of the source point under the desired transformation. Three control
- vectors allows defining a fully general affine transformation.
- @param src0
- @param src1
- @param src2

- @param dest2

- Creates a transformation from a set of three control vectors. A control

createFromControlVectorsCL(
List< Coordinate?> src, List<Coordinate?> dest) → AffineTransformation? -
- Creates an AffineTransformation defined by a set of control vectors.
- Between one and three vectors must be supplied.
