The Spatial Companion for Oracle – Affine Edition(AF4O) is a collection of functions for performing AFFINE transformations.
The functions break down by the method of implementation.
The Methods are:
1. Algorithm Implemented using Pure PL/SQL
2. Transformations implemented using Oracle matrix processing capability.
3. Affine transformations implemented as wrappers over the MDSYS.SDO_UTIL.AFFINETRANSFORMS package.
- It is important to note that these functions simplify access to the MDSYS.SDO_UTIL.AFFINETRANSFORMS functions based on categorized access eg Rotate, Move, Scale.
