TIFF is much more powerful and flexible file format. You can store almost any C data type (signed/unsigned 32 bit integer, floating point, complex values). That is widely used in the area where I'm working (geospatial and remote sensing applications, scientific data processing). Also we have widely approved and working GeoTIFF extension. Nothing similar for PNG. For me TIFF is most comfortable image file format, the only limitation is 4GB barrier. PNG has its own advantages, namely it is fully streamable. These are different formats designed with different goals in mind. Andrey -- Andrey V. Kiselev Home phone: +7 812 5274898 ICQ# 26871517
