===================================================================== PEG ``transform_definitions--tjl``: New coordinate system definitions ===================================================================== :Author: Tuomas J. Lukka :Last-Modified: $Date: 2003/03/31 10:00:03 $ :Revision: $Revision: 1.1 $ :Status: Incomplete The previous PEGs on coordinate systems were a tad unclear on the overall goals - hopefully these new methods will clarify the picture. For example, a box coordinate system and an aspect ratio coordinate system (a mapping from (0,w)x(0,1) to (0,1),(0,1)) we can define a padded text coordinate system (i.e. one which has isotropic coordinates relative to the parent coordinate system) based only on these two coordinate systems:: def paddedText(box, aspectratio): vs. Changes -------
