**CIGAL Reference Manual, Chapter 4 (Variables): iflags**
===== Iflags -- Integer variable controlling image processor options =====
**usage:  iflags = value**

IFLAGS is an internally defined integer variable controlling options
related to how image processor operations are executed. IFLAGS values
provide a way to select hardware dependent options and their meanings
will therefore vary for different image processing hardware.  The
value of the IFLAGS parameter can be changed at any time and remains
set until it is explicitly modified again.  The meanings of the IFLAGS
settings are summarized below; levels can be combined by adding values.
         Value
           1        Switch "outmode" to 1 (default 0) for image reading and
                     writing. Mode 0 is faster i/o but display tends to
                     flicker, compared to mode 1.
           2        Use direct memory access (no buffering) for image processor
                     I/O.
