[Geotools-gt2-users] Problems reading huge rasters

[César M. I. <ces...@gm...>]

I need to process huge rasters with GeoTools, but it seems I've found
its limit :-(

INFO: Unable to find crs, continuing with default WGS4 CRS
Exception in thread "main" java.lang.IllegalArgumentException:
Dimensions (width=59000 height=46000) are too large

The relevant code follows:

		File file = new File("d:\\bigtab\\mosaic.asc");
		ArcGridFormat agf = new ArcGridFormat();
		GridCoverageReader reader = agf.getReader(file);

Have you found a similar problem? Is there any workaround?
I see it is a problem with JAI... is there any chance to replace the
"limited" classes with another non-JAIs classes?
