# RS_GeoTransform

Returns a struct of parameters that represent the GeoTransformation of the raster. The struct has the following schema:

* magnitudeI: size of a pixel along the transformed i axis
* magnitudeJ: size of a pixel along the transformed j axis
* thetaI: angle by which the raster is rotated (Radians positive clockwise)
* thetaIJ: angle from transformed i axis to transformed j axis (Radians positive counter-clockwise)
* offsetX: X ordinate of the upper-left corner of the upper-left pixel
* offsetY: Y ordinate of the upper-left corner of the upper-left pixel
