Description
The various [Transform] methods in the CCoordinateSystemTransform class trim input coordinates if the source coordinate system is geographic and the [IgnoreOutsideDomainWarning] flag is set.
Mg API thus returns different values then CSMAP does. For example, running CSMAP's TEST.DAT file through the mg API isn't possible.
Note:
See TracTickets
for help on using tickets.
Fixed in changeset 6532 (see http://trac.osgeo.org/mapguide/changeset/6532 for more/technical details).
The CCoordinateSystemTransform class does now no longer 'adjust' any geographic coordinate before passing them to CSMAP.
