           Summary: Documrntation on banding is unclear.
           Product: Ghostscript
           Version: HEAD
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: normal
          Priority: P4
         Component: Documentation
        AssignedTo: support at artifex.com
        ReportedBy: leonardo at artifex.com

End users want to know about Ghostscript banding methods from Use.htm . However 
this file contains only a misleading information about MaxBitmap. Some 
documentation onm banding parameters appears in Language.htm, but (1) end users 
can't understand this document because it is for Postscript programmers, (2) 
it's unclear how these parameters control the algorithm (3) from parameter 
names they look contradicting one another. For example, what happens if I set 
BandWidth=10, MaxBitmap=10000000 : will it cause vertical bands ???

Also need to explain that default settings are optimal for for 60 dpi A4, and 
they may be very inoptimal for bug pages such as bug 689155. Therefore big 
pages either need an improvement for the default setting code, or a manual 
adjustment for parameters.
