----------------------------------------------------------------
Key: GEOT-2810
URL: http://jira.codehaus.org/browse/GEOT-2810
Project: GeoTools
Issue Type: Bug
Components: core render
Affects Versions: 2.5.8
Environment: java version "1.6.0_16"
Java(TM) SE Runtime Environment (build 1.6.0_16-b01)
Java HotSpot(TM) 64-Bit Server VM (build 14.2-b01, mixed mode)
Windows XP 64 bit
Reporter: Per S Hustad
Assignee: Andrea Aime
Attachments: grid10x10.tif, GridCoverageRendererTest-patch.txt,
testRotatedCoverage.tif

The GridCoverageRenderer is still not rendering rotated grid coverages
correctly. See the attached testRotatedCoverage.tif screenshot, obtained from
running the supplied GridCoverageRendererTest.testRotatedCoverage() with
-Dorg.geotools.test.interactive=true.
Before running the test, you will have to copy the grid10x10.tif attachment to
the /gt-render/src/test/resources/org/geotools/renderer/lite/test-data/
directory.
The rotated grid coverage is jagged along the image borders. We have traced
this to the org.geotools.coverage.processing.operation.CroppedCoverage2D.create
method where the Mosaic image is produced. I tried to figure out a safe way of
extending the image ROI regions but finally gave up.
