Hi Lorenzo, it's because GeoTiffReader returns a deferred loading image, that is not really read in memory, but has a connection to the source file and reads tiles on demand.
The ability to serializing a GridCoverage2D really depends on how serializable the RenderedImage inside of it is. In general, we never use serialization, but write the coverage to a suitable output format (e.g., using the GeoTiffWriter for example). It's not a general mechanism, each format has its own limitations, no format that I'm aware of allows to save random image types, but GeoTiff normally provides good coverage for most sample models and color models. Hope this helps Cheers Andrea On Wed, Jan 6, 2021 at 2:58 PM Lorenzo Di Giacomo <loridi...@gmail.com> wrote: > Hi, i was trying to serialize a GridCoverage2D (read from file using > GeoTiffReader) with the same snippet used in "GridCoverageTestBase.java", > but > when i try to do it i always get "java.lang.RuntimeException: > > it.geosolutions.imageio.stream.input.FileImageInputStreamExtImplNon-serializable > parameter in this operation`s ParameterBlock." > Do you know why is this happening?
