Fwd: convert tld to other format

[David Belnap]

The format Liang refers to comes from the Z/I (Zeiss) SCAI scanner 
software called Phodis.  Phodis runs on an SGI and controls the SCAI 
scanner.  As far as I can tell, the TLD format is unique to that 
package.  We usually scan images as TLD (so we can use the Phodis 
display and histogram utility).  For storage, we convert the images to 
TIFF with another Phodis utility.  (One can scan directly to TIFF with 
Phodis but then cannot use the Phodis display/histogram utility unless 
the image is converted to TLD.)

Storing Phodis-scanned images in TLD format brings the risks that Liang 
discovered.  It is better to store as TIFF.
