MapProjection: relax coordinate checks/make them configurable
-------------------------------------------------------------
Key: GEOT-1745
URL: http://jira.codehaus.org/browse/GEOT-1745
Project: GeoTools
Issue Type: Improvement
Components: core referencing
Affects Versions: 2.4.2, 2.5-M1
Reporter: Andrea Aime
Assignee: Martin Desruisseaux
Fix For: 2.4.2, 2.5-M1
As reported in this mail thread:
http://www.nabble.com/Relaxing-coordinate-checks-in-MapProjection--td16154359.html
it would be very useful to relax the current bound checks on MapProjection
(line ...) as they are breaking rendering in at least two applications
depending on GeoTools (GeoServer and uDig).
Implementation ideas:
* add a new hint to ask for transform leniency
* use the current "lenient transform" hint to act on bound checks as well
The latter is probably the easiest way, but has backwards compatibility issues.
At the moment the CRS.findMathTransform(from, to , lenient) javadoc states:
{code}
param lenient [EMAIL PROTECTED] true} if the coordinate operations should be
created
even when there is no information available for a datum shift.
{code}
Most datastore and rendering code sets lenient to true in order to get a best
effort behaviour, so the change proposed above would be consistent with the
current intended usage, but not fully with the javadoc (thought it can be
argued that it doesn't say anything about exception being thrown either, so the
current behaviour is not specified in the javadocs either?).
