Hello-
I am trying to do perform a simple reprojection test taking a WGS84 image
to
a "Google" map projection ("EPSG:900913"). I lifted code from this thread:
http://www.mail-archive.com/[email protected]/msg02294.html
Here's the code:
----------
BufferedImage bi = ImageIO.read(
new File("C:/My Documents/earth.jpg"));
Envelope2D envelope = new Envelope2D(CRS.decode("EPSG:4326"),
new java.awt.geom.Rectangle2D.Float(-180, -90, 360, 180)
);
GridCoverage2D gc2d = new GridCoverageFactory().create("BMImage", bi, envelope);
GridCoverage2D gc2dProj =
(GridCoverage2D)Operations.DEFAULT.resample(gc2d,
CRS.decode("EPSG:900913"));
ImageIO.write(gc2dProj.getRenderedImage(), "JPEG",
new File("/temp/reproject_out.jpg"));
----------
I'm getting the following error:
----------

Operator error I'm sure. Any suggestions?
Thanks,
