Extended IDL Help

view3d_slicer.pro

At present this program is installed in the /usr/local/epics/extensions/idllib directory for EPICS R3.14. This program provides IDL users a widget application VIEW3D_SLICER to flexiblely access the 2D data from the 3D data array. Currently, the 3D data must be automatically saved by the IOC scan software in XDR format.

VIEW3D

 [Next Routine] [List of Routines] 
 NAME:
       VIEW3D 

 PURPOSE:
      This routine cut out a cartesian 2D slice from an arbitrary
      input 3d array. It allows the user view the 2D slice as 
      various 1D/2D plots or ASCII output.

 CATEGORY:
    Widgets.

 CALLING SEQUENCE:
	VIEW3D, Da3D [,Kindex] [,Rank] [,SLICER3=slicer3] [,TITLE=title]
                  [,GROUP=group] [,DATA=data]

 ARGUMENTS:
    Da3D:    Input 3D array to be examined
    Kindex:  Specifies the index number of the slice, zero based number, 
             default 0 
    Rank:    Specifies the viewing direction rank number, 0-X axis, 
             1-Y axis, 2-Z axis, default 2 

 KEYWORDS:
  SLICER3:   Specifies whether slicer3 is called 
  TITLE:     Specifies the tile for 2D plot
  GROUP:     Specifies the widget ID of the parent group
  DATA:      Returns the cut out 2D data array slice

 RESTRICTIONS:
    The environment variables must be set by source in 
    /usr/local/epics/extensions/bin/solaris/setup_ezcaIDL for IDL 5.1
    /usr/local/epics/extensions/bin/solaris/ezcaidl_setup for IDL 5.3
    All required programs will be automatically loaded into IDL by this
    setup.

VIEW3D_SLICER

 [Previous Routine] [List of Routines] 
 NAME: 
    VIEW3D_SLICER
 
 PURPOSE:
    This routine provides a flexible 2D slicer for the 3D scan data 
    automatically saved by the IOC scan software. 
    It provides the option of generating various 2D image plots, 2D
    ASCII report, and a table driven 1D plots of various columns and
    rows of the 2D data.

 CATEGORY
    Widgets.

 CALLING SEQUENCE:
    
    VIEW3D_SLICER, File='filename', GROUP=group

 KEYWORD PARAMETERS:
    FILE:       Specify the input scan filename saved by the IOC scan 
                software, the file name is sequenced by the scanno and
                prefixed with uid and suffixed with '.scan', e.g.
                'uid:_nnnn.scan'

    DMAX:       Specify the maximum number of detectors, 15 for scan 4.1
                85 for newer

    GROUP:      Specify the widget ID of the group leader of the widget.
                The death of the group leader results in the death of the
                VIEW3D_SLICER.

 RESTRICTIONS:
    The input filename must be a 3D scan saved by the IOC.

 EXAMPLES:

       VIEW3D_SLICER, File='cha:_0049.scan'
