It seems to me that Photoshop compatibility could conflict with your
desire to store different data types (byte, long, float). According to
the Photoshop 5.0 info at
http://www.adobe.com/prodindex/photoshop/prodinfo.html,
"File-format and Cross-platform Compatability
Support for Web publishing file
formats, including GIF89a, PNG,
Progressive JPEG, and Adobe
Portable Document Format (PDF)
Support for graphics file formats,
including Encapsulated PostScript (EPS,
including Adobe Illustrator), Kodak(R)
Photo CD(TM), TIFF, JPEG, Scitex(R)
CT, DCS, PCX, BMP, PIXAR,
PixelPaint(TM), MacPaint(R), Raw,
Targa (TGA), CompuServe(R) GIF,
and Amiga IFF/LBM"
I don't know if any of these formats support multiple data types.
If you're looking for a file format that is platform independent,
supports different data types, and is IDL compatible, then I'd choose
netCDF (http://www.unidata.ucar.edu/packages/netcdf/index.html)
Cheers,
Liam.
