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.

e encoder for png which should make things a bit faster anyway.
Let us know if you have more problems.

One advice. please install the JAI ImageIO tools package since it ships with
a nice
native encoder for png which should make things a bit faster anyway.
Let us know if you have more problems.

Hi Simone/Andrea,
I'm using:
Java jre1.5.0_04
JAI installed from: jai-1_1_3-lib-windows-i586-jre.exe
ImageIO from standard Java API - no native installs
I isolated the slowness to this line in GridCoverageRenderer:
graphics.drawRenderedImage(finalImage, cloneFinalWorldToGrid);
After
Ciao Andrea,
I doubt it depends on differences between 2.3.0 and the actual code,
but I want to check.
Since the timed code contains a write operation performed using
ImageIO directly it might be and old version of ImageIO giving
problems, or the absence of the native codec for PNGs, or difference

Steve, can you try again using the 2.3.x nightly builds at:

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.
A workaround

Ouch... it shouldn't be
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 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 (
