Brent Dove" To: IT List Subject: Re: tifMessage-ID: <01I30QHQ9PIM00GGO6@uthscsa.edu>Hello Heberto,As a matter of clarification UTHSCSA ImageTool does not support anything less that 8 bit TIF files.  Unfortunately you will need to convert the images to an 8 bit tif and then load them in.  If there is a real need for supporting lower bit images we will consider it in a future release.  Any comments on this subject would be appreciated.S.

I have a problem with"pkunzip"ing the idsdk.zip file (875073 bytes long and dated 3/27/96). I encountered two files (include/ps/piprop~1.h and piutil~1.h) which fail the CRCcheck. They are both empty files. I wonder if any body else experiences thesame problem.
