Ciao Ferdinando, let's clarify this point. GeoTools uses a special version of the ImageIO tiff reader/writer that drifed away from the standard SUN/Oracle one in order to evolve and improve. The two companies did not seem to have any respect for the ImageIO project so we created ImageIO-Ext http://java.net/projects/imageio-ext/.
Now, the tiff reader per-se is pure java and OS indipendent (it does not care about 32/64 bits, little/big endian) so, generally speaking things shoudl work fine on win64. As usual there is one issue. If your geotiff tiles are encoded in JPEG then you need a JPEG encoder. Since ImageIO has no native codec availabe for Win64 the reader should revert to using the one inside the JDK/JRE which is a little slower but things should work seamlessly. Long story short, I don't think you need to worry about Imageio under win64 since what you are referring as installing ImageIO I believe means installing the native libs required by some ImageIO plugins for better performance. In your case I would say that no features should be lost and performances should not be affected. Regards, Simone Giannecchini ------------------------------------------------------- Ing.
