Possibly.  I realized that this option is not PDF-specific, as I just 
today gave it a try with Postscript input on the tiffg3/tiffg4 device.

However, I haven't yet investigated how long this option has been 
available to Ghostscript, or if it's a relatively new feature that won't 
be available on older systems.

Furthermore (and more importantly), this option has gotten no exposure 
at all with HylaFAX users yet, and so it's hard to say if -dPDFFitPage 
meets users' expectations better or worse than -dFIXEDMEDIA does (or as 
I've been accustomed to doing: code-modifying -dAdjustWidth to work 
"better" for variable-length documents).  I'm completely comfortable 
making a default change when we have these two uncertainties resolved.

Neither -dFIXEDMEDIA nor -dPDFFitPage offer an ideal solution to the 
case where a single multi-page document contains pages of a varied 
length (i.e. mixed letter and legal pages).  That's what my 
-dAdjustWidth patch (that's on the Ghostscript Bugzilla) was intended to 
support.  But like -dFIXEDMEDIA it can also cut-off the right side of 
image data.

And none of this does any good for cases where the page really should be 
rotated before being "fitted" or "trimmed".  That's what the Ghostscript 
option of -dAutoRotatePages=/PageByPage is *supposed* to handle, I 
believe.  And when I last tested that option I didn't see it doing 
anything... but I may have been doing something wrong or I may have been 
using a buggy version of Ghostscript at the time, too.  I'll have to 
revisit -dAutoRotatePages=/PageByPage sometime...

Thanks,

Lee.
