: [Geotools-gt2-users] Slow rendering of GridCoverage objects
Hi Andrea/Simone/Martin,
I threw together a quick example that reproduces the problem. It took 159
seconds to produce the image.
Thanks again for the help.

Ciao Steve,
I need a couple more info about your platform:
java version
os
JAI and ImageIO version
I ran your example as it was (well, to be honest I removed the line
where you were showing the created coverage) and I got the following
execution

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);

Hi Andrea,
I'm manually creating the GridCoverage from a WritableRaster using:
GridCoverage2D gc = gcFactory.create(My colored coverage, raster,
envelope, minValues, maxValues, null, new Color[][]{colors},
null);
Thanks for the help!

Hello,
I had the same problem some month ago (see my posting from Dec 16, 2006)
and still didn't find a solution. While rendering, the memory usage
increases continuously. If it would be helpful, I could send a detailed
stack trace showing where the renderer spends that much time.
