**fScan Reference Manual, Chapter 3 (KeyCmds:ImageKeys): adjust **
===== Adjust -- Generate a series of images by adjusting one display parameter =====
**usage: key,framesize,stepsize,nframes,frame0,flg A**

The ADJUST command generates a new image series data set out of an existing data set, by creating multiple views of the original data set while varying one display parameter. The data set being adjusted can be either an image data set or a 3D surface data set.  If it is an image data set, it must be in the single frame display mode (see [[jvs:fscan:manual:chapter3:imagekeys:config|Config]]) because only one frame can be adjusted at a time.

The arguments to the ADJUST command are:

KEY - which display parameter is to be manipulated 
	
  key=0  The most recent interactive adjustment mode -- move_key()
      1   brightness
      2   threshold
      3   slice
      4   timepoint
      5   offset
      6   scale
      7   rotate
      8   zoom
      9   morph
     10   contrast
     11   color
     12   transparency
   The following values can be added to KEY  
    100   X axis
    200   Y axis
    300   Z axis
   1000   Thumbnail flag -- combined with other modes
		
FRAMESIZE - How big to make the width of new data set images (frame height will be adjusted to have the same aspect ratio as the input images)

  framesize > 10 - desired framewidth in pixels ().
           <= 10 - the ZOOMINDEX factor as:
        Framesize    Scale factor
            0             1
            1            1.5
            2             2
            3             3
            4             4
           ...
           -1            2/3
           -2            1/2
           -3            1/3
           -4            1/4
           ... 

STEPSIZE - how big is each frame adjustment step\\
NFRAMES - how many adjustment images to create\\
FRAME0 - which window frame to use as reference image\\
FLG - option flag (bit flag, combine options by adding values):
   flg: 1 - center adjustment:  1/2 the frames should be down and half up
            (relative to frame0 starting value); frame0 will appear in middle 
            of adjustment list
        2 - animate result

Note: If an image INSET has been specified using the [[jvs:fscan:manual:chapter2:setinset|SET INSET]] command, then an image from the INSET data set will be inserted as an inset into each frame of the image series created by ADJUST.
