Exception when cropping to small region
---------------------------------------
Key: GEOT-1814
URL: http://jira.codehaus.org/browse/GEOT-1814
Project: GeoTools
Issue Type: Bug
Components: core coverage
Affects Versions: 2.4.2
Environment: Wndows XP and JRE 1.6, although the problem seems generic
Reporter: Nick Newman
Assignee: Martin Desruisseaux
Priority: Minor
On line 311 of release 2.4.2 of
org.geotools.coverage.processing.operation.CroppedCoverageD.java (version
30268) the following code is found:
final GeneralGridRange newRange = new GeneralGridRange(new
GeneralEnvelope(finalGridRange));
If the finalGridRange is small the newRange can become empty because of the
rounding to integers that occurs in the GeneralGridRange constructor. This
results in the error "The rectangular crop area must not be empty" in the JAI
calls a little later.
