Before we show how to call these routines from other command files, we shall write a routine to contour a series of buffers into a single one.
################################################################ # Contour.CMD # # Command sequence for contouring a series of buffers at a # # specific contour level. # # # # Passed: # # !!1 First buffer to be contoured # # !!2 Last buffer to be contoured # # !!3 Buffer to place contours in. Note that this # # should be erase first, if desired. # # !!4 Intensity of contour # # !!5 Minimum contour length # # !!6 Length to smooth contours over # # Local: # # !!0 Used to store contour plot intensity # ################################################################ # Start from main menu ; Return to main menu # If this command file is nested, then assume !!1, !!2 and !!3 # contain required values, otherwise prompt user for buffer range !!L>0 :RangeSpecified !^ First buffer to be contoured ? !!1:=!!B !^ Last buffer to be contoured ? !!2:=!!B !^ Place contours in which buffer ? !!3:=!!B !^ Contour which intensity !!4:=!!K !^ Minimum contour length (shorter contours will not be plotted) !!5:=!!K !^ Smooth contours over what length ? !!6:=!!K !!:RangeSpecified # Enter Contours menu. There may be a delay while DigImage changes # program modules. C: Contours and Edges # Initialise plot intensity !!0:=255 !!:NextSourceBuffer # Contour each buffer in turn, using the current default window C Contours !!1 # Find contours on buffer !!3 # Plot on buffer Window for contours Grab window !!4 # Contour threshold intensity !!0 # Contour plot intensity !!5 # Minimum contour length !!6 # Length to smooth contours over # Increment counters etc. and check for end of loop !!1:=!!1 + 1 # Next source buffer !!0:=!!0 - 8 # Next plot intensity !!1<=!!2 :NextSourceBuffer ; Return to main menu |
