CIGAL Reference Manual, Chapter 2 (Commands): CALL
usage: call PRIMITIVE argument_list
Several low-level device-dependent subroutines are called as “primitive” functions using the CALL command. These primitives include all of the image processor specific routines (if available). To get a complete (but terse) list of all available primitives type:
call help
NOTE: There is no on-line help for the primitive functions except 'call help'. Refer to the appropriate hardware user's manual for more information on these routines.
