[Geotools-gt2-users] Slow rendering of GridCoverage objects

[Steve.Ansari <Ste...@no...>]

Hello all,

I'm using StreamingRenderer to draw a MapContext with the 2.3.0 release, 
however it is VERY slow when drawing a GridCoverage layer.  I've 
isolated the problem to:

            graphics.drawRenderedImage(finalImage, cloneFinalWorldToGrid);

in GridCoverageRenderer ( 
http://svn.geotools.org/geotools/trunk/gt/modules/library/render/src/main/java/org/geotools/renderer/lite/gridcoverage2d/GridCoverageRenderer.java 
)

My GridCoverage is 800x800 and the drawing time is around 1 minute.

Has anyone else had these problems or found a workaround?

Thanks,
Steve
